Findings Of Fact Savanah McGriff was, until her death, a resident of Gadsden County. The parties have stipulated that on November 1, 1977 she was admitted to the Tallahassee Memorial Hospital in an emergency medical condition, and that the treatment performed by the hospital was of an emergency nature. The parties have further stipulated that the Tallahassee Memorial Hospital is a regional referral hospital within the meaning of 154.304(4), Florida Statutes (1977). Savanah McGriff was admitted to the Tallahassee Memorial Hospital on November 1, 1977. She died on November 3, 1977 while she was still a patient at the hospital. The total bill for services was $683.85. The hospital submitted a bill to Gadsden County in the amount of $253.58 for the services, which is the amount permitted to be billed in accordance with the Florida Health Care Responsibility Act. Gadsden County has refused to pay the bill, contending that the patient was not indigent within the meaning of the Act. The bill has not been otherwise paid. Savanah McGriff was married to Charlie Anderson. During the six months preceding the hospitalization of Savanah McGriff, she and her husband resided together in their home. During that period Mr. Anderson received a monthly disability check of $74.70, and Social Security benefits in the amount of $116.10. Ms. McGriff had received Veterans benefits in the amount of $50.40. They had no other income. Their average monthly income for the six months prior to the hospitalization was thus $241.20.
The Issue Whether the Respondent's policy of requiring justification of a hospital's rate of increase in its GRAA in excess of the National Hospital Input Price Index (hereinafter referred to as the "NHIPI") is an invalidly promulgated rule?
Findings Of Fact The following findings of fact were contained in the Joint Prehearing Stipulation: The Petitioner's name and address are Doctors Memorial Hospital, 401 E. Byrd Avenue, Bonifay, Florida 32425. Doctors Memorial is a 34-bed short-term general acute care hospital located and operating in Holmes County. Doctors Memorial is owned by National Healthcare of Holmes County, Inc. The name and address of the agency affected are the Hospital Cost Containment Board, Executive Office of the Governor, State of Florida, Woodcrest Office Park, Building L, Suite 101, 325 John Knox Road, Tallahassee, Florida 32303. The HCCB I.D. number of Doctors Memorial is 10-0078. On or about March 27, 1986, Doctors Memorial submitted to the HCCB its projected 1987 fiscal year budget. Doctors Memorial's 1987 fiscal year begins on July 1, 1986, and runs through June 30, 1987. On May 16, 1986, Doctors Memorial received the Staff analysis and preliminary findings and recommendations relative to its 1987 fiscal year budget. Doctors Memorial was advised that the Staff would recommend to the HCCB that Doctors Memorial's budgeted gross revenue per adjusted admission and net operating revenue per adjusted admission for fiscal 1987 be adjusted downward for reasons set forth in the Staff analysis. Doctors Memorial timely filed its petition challenging Staff's recommendations on May 30, 1986. Doctors Memorial has standing in these matters based on the facts alleged in its petitions. The Respondent indicated in its preliminary findings and recommendations that the following policy applied to the review of the Petitioner's 1987 budget: Current agency policy states that hospital's [sic] exceeding the MARI can only increase gross revenue per adjusted admission to the National Hospital Input Price Index (NHIPI) of 3.7 percent without further justification. Any increase in excess of the NHIPI must be sufficiently justified and quantified to staff. The NHIPI is an average rate of inflation for hospitals in the United States. It represents the additional costs of providing services by hospitals in the country caused by inflation. The policy contained in the Respondent's preliminary findings and recommendations was developed and imposed upon the Petitioner after the Respondent's analysis, Mr. Lasko, had made an initial draft of his review of the Petitioner's budget for fiscal year 1987. After learning of the policy, Mr. Lasko redrafted his review which was signed on May 15, 1986 and subsequently sent to the Petitioner. The policy contained in the Respondent's preliminary findings and recommendations was contained in a memorandum dated May 16, 1986 (hereinafter referred to as the "May 16 Memorandum"), and signed by Mr. Pattillo, the Chief Financial Analyst of the Respondent, on May 22, 1986. In the May 16 Memorandum it was stated that: Any increase over the previous year's GR/AA inflated by the NHIPI, shall be justified by the hospital to the staff's satisfaction utilizing the statutory review criteria of section 395.509(5), Florida Statutes. The policy contained in the Respondent's preliminary findings and recommendations and its May 16 Memorandum, based upon instructions contained in the May 16 Memorandum, is to apply to all 1987 budgets that are subject to budget review. The policy contained in the May 16 Memorandum was further explained in a memorandum dated June 19, 1986 (hereinafter referred to as the "June 19 Memorandum"). The June 19 Memorandum was signed by Mr. Pattillo. In the June 19 Memorandum it was indicated that hospitals subject to review may even have to justify an amount of increase less than the NHIPI. The policy of the Respondent embodied in its May 16 Memorandum and its June 19 Memorandum has not been adopted as a rule pursuant to Section 120.54, Florida Statutes (1985).
Findings Of Fact The rule at issue has been variously codified, but will be referred to for purposes of the present case as Rule 10C-7.39(6), Florida Administrative Code. The pertinent language, which was first adopted as part of Rule 10C- 7.03(5), Florida Administrative Code, on March 30, 1976, and which was repealed on July 28, 1981, provides: Reimbursement for services provided is in accord with the standards and principles of reasonable cost as defined and applied under the Social Security Act, Title XVIII, Medicare Program. In lieu of retroactive adjustment, 6 percent shall be added to a participating hospital's costs to determine a current reimbursement rate. Respondent adopted this rule on the claimed authority of Section 409.266, Florida Statutes. In its 1969 legislative session, the Florida Legislature enacted Section 409.266, Florida Statutes, entitled "Medical Assistance for the Needy," providing the original State legislative basis and authority for Florida's entry into the Medicaid program. Section 409.266(2), Florida Statutes, as enacted, authorized the Florida Department of Social Services or any other department that the Governor might designate to: Enter into such agreement with other state agencies or any agency of the federal government and accept such duties with respect to social welfare or public aid as may be necessary to implement the provisions of subsection (1) and to qualify for federal aid including compliance with provisions of Public Law 86-778 and the "Social Security Amendments of 1965" [estab- lishing Title XIX of the Social Security Act.] Section 409.266(3), Florida Statutes, as enacted, stated that: The department of social services is authorized and directed to prepare and operate a program and budget in order to implement and comply with the provisions of public law 86-778 and the "Social Secu- rity Amendments of 1965." Chapter 69-265, Laws of Florida (1969). No provisions of Florida law other than Section 409.266, Florida Statutes, as enacted, authorized any agency to perform any function specifically to implement the Medicaid program. The State of Florida formally commenced participation in the Medicaid program effective January 1, 1970. At all times pertinent to this controversy, respondent, Florida Department of Health and Rehabilitative Services or its predecessor agencies (referred to as "HRS") , has been and continues to be the "State Agency" identified in 42 U.S.C. Section 1396a (a) (5), and charged under Section 409.266, Florida Statutes, as amended, with the formulation of a State Plan for Medical Assistance ("State Plan"), 42 U.S.C. Section 1396a, and with the ongoing responsibility for the administration of the Medicaid program in the State of Florida. Since Florida's entry into the Medicaid program in 1970, HRS has been authorized essentially to "[e]nter into such agreements with appropriate agents, other State agencies, or any agency of the Federal Government and accept such duties in respect to social welfare or public aid as may be necessary or needed to implement the provisions of Title XIX of the Social Security Act pertaining to medical assistance." Section 409.266(2)(a), Fla. Stat., as amended. HRS has never been authorized to enter into any agreements, accept any duties, or perform any functions with respect to the Medicaid program that are in contravention of or not authorized by Title XIX of the Social Security Act and implementing Federal regulations and requirements. As a prerequisite for Florida's entry into the Medicaid program, HRS prepared and filed with the United States Department of Health, Education, and Welfare ("HEW") a State Plan, pursuant to Title XIX of the Social Security Act, and pursuant to its delegated legislative authority set forth in Section 409.266(2)(a), Florida Statutes. (In May, 1980, HEW was redesignated the United States Department of Health and Human Services, but for purposes of this action both shall be referred to as HEW.) C.W. Hollingsworth was the HRS official who had the responsibility for supervising the preparation, the filing, and for obtaining the approval of HEW of Florida's initial State Plan Florida's initial State Plan was approved by HEW effective January 1, 1970. At the time that Florida received approval of its initial State Plan, Title XIX of the Social Security Act required state plans to provide for the payment of the reasonable cost of inpatient hospital services. At the time that Florida received approval of its initial State Plan, HEW regulations governing reimbursement for inpatient hospital services under Medicaid required the State Plan to provide for reimbursement of Medicaid inpatient hospital services furnished by those hospitals also participating in the Medicare program, applying the same standards, cost reimbursement principles, and methods of cost apportionment used in computing reimbursement to such hospitals under Medicare. 45 C.F.R. Section 250.30(a) and (b), 34 Fed. Reg. 1244 (January 25, 1969). At the time that Florida entered the Medicaid program, Medicare cost reimbursement principles in effect governing reimbursement for the cost of inpatient hospital services required payment of a participating hospital's actual and reasonable costs of providing such services to Medicare beneficiaries, and, moreover, that such payment be made on the basis of the hospital's current costs rather than upon the costs of a prior period or upon a fixed negotiated rate. 42 U.S.C. Section 1395x (v) (1)(A) 20 C.F.R. Section 405.451(c) (2), 405.402(a) [later renumbered 42 C.F.R. Section 405.451(c)(2) and Section 405.402(a)]. Such Medicare principles and standards also provided for interim payments to be made to the hospital during its fiscal year. At the conclusion of the subject fiscal year, the hospital was required to file a cost report wherein the hospital included all of its costs of providing covered inpatient services to Medicare beneficiaries. A settlement or "retroactive adjustment" process then was required to reconcile the amount of interim payments received by the hospital during the fiscal period with its allowable costs incurred during that period. If the hospital had been overpaid during the year, it was required to refund the amount of that overpayment to the Medicare program. Conversely, if the hospital had been underpaid during the year, the Medicare program was required to make an additional payment to the hospital, retroactively, in the amount of the underpayment. 20 C.F.R. Section 405.402(b)(2), 405.451(b)(2). Essentially the same Medicare principles and standards governing reimbursement of inpatient hospital services described in the two preceding paragraphs have been in effect at all times pertinent to this controversy. 42 C.F.R. Section 405.401, et seq. Florida's approved State Plan as of January 1, 1970, governing reimbursement of inpatient hospital services under the Medicaid program, committed HRS to reimburse hospitals that also participated in the Medicare program for their reasonable costs of providing inpatient hospital services to Medicaid patients, applying Medicare cost reimbursement principles and standards. The only versions of Florida's State Plan provisions that have been approved by HEW and that have governed HRS's reimbursement of inpatient hospital services prior to July 1, 1981, each commit HRS to reimburse hospitals that also participated in the Medicare program for their reasonable costs of providing inpatient hospital services to Medicaid patients, applying Medicare cost reimbursement principles and standards. Attached as an appendix to the final order is the form agreement drafted under the supervision of C.W. Hollingsworth, which has been in use from January 1, 1970, until July 1, 1981. From the inception of the Florida Medicaid program, and as a prerequisite for participation therein, a hospital has been required to execute a copy of the form agreement. A hospital may not participate in the Medicaid program without having executed such an agreement, nor may it propose any amendments thereto. The intent and effect of the form agreement is to require HRS to reimburse hospitals that also participated in the Medicare program for their reasonable costs of providing inpatient hospital services to Medicaid patients, applying Medicare cost reimbursement principles and standards. The form agreement requires HRS to compute a percentage " allowance in lieu of the retroactive adjustments ("percentage allowances") in determining the rates that hospitals will be paid for providing inpatient hospital services to Medicaid patients. The form agreement requires HRS to compute a new percentage allowance each year based on hospital cost trends. The meanings of the terms "allowance in lieu of retroactive adjustments" in all pertinent state plans and "percentage allowance for the year in lieu of retroactive payment adjustment" contained in the form agreement are identical. In drafting the form agreement, HRS intended that the "percentage allowance for the year in lieu of retroactive payment adjustment" be set at a level sufficient to ensure that hospitals participating in the Medicaid program would be reimbursed their "reasonable costs" of providing inpatient hospital services to Medicaid patients, applying Medicare cost reimbursement principles and standards. At all times pertinent to this controversy, participating hospitals, like petitioner, have been reimbursed by HRS for inpatient hospital services provided to Medicaid patients in the following manner: Within ninety (90) days following the close of its fiscal year, the partici- pating hospital files a Form 2551 or 2552 Annual Statement of Reimbursable Costs, as applicable, with both Blue Cross of Florida, Inc., the major fiscal intermediary respon- sible for the administration of Part A of the federal Medicare program in the State of Florida, and with HRS. This document, also referred to as a "cost report" details various hospital and financial statistical data relating to the patient care activities engaged in by the hospital during the sub- ject fiscal period. Upon receipt of the participating hospital's cost report for a fiscal period, HRS makes an initial determination based upon Medicare cost reimbursement principles and standards of the hospital's total allow- able inpatient costs, charges, and total patient days during the subject fiscal period, and then determines an inpatient per diem reimbursement rate for the period. To the inpatient per diem reimburse- ment rate is then added a percentage allow- ance in lieu of making any further retroactive corrective adjustments in reimbursement which. might have been due the hospital applicable to the reporting period. The adjusted in- patient per diem reimbursement rate is applied prospectively, and remains in effect until further adjustments in the rate are required. If HRS determines that total inpa- tient Medicaid reimbursement to a partici- pating hospital during a fiscal period exceeds the hospital's allowable and rea- sonable costs of rendering such covered inpatient services applying Medicare cost reimbursement principles and standards, then the hospital is required to remit to HRS the amount of such overpayment. If, however, HRS determines that the total inpatient Medicaid reimbursement received by a participating hospital is less than the hospital's actual and reason- able costs of rendering such covered inpa- tient services to Medicaid patients during the period applying Medicare cost reimburse- ment principles and standards, no further retroactive corrective adjustments are made; provided, however, that should an overpayment occur in a fiscal period, it may be offset and applied retroactively against an under- payment to the participating hospital which occurred during the next preceding fiscal period only. HRS has used the following "percentage allowances" in determining Medicaid reimbursement rates for inpatient hospital services: January 1, 1970-June 30, 1972 ...12 percent July 1, 1972-approximately March 30, 1976 ... 9 percent Approximately March 31, 1976-June 30, 1981... 6 percent Since at least January 1, 1976, HRS has not recomputed the "percentage allowance" on an annual basis. Since at least January 1, 1976, HRS has not based the "percentage allowance" that it has applied in determining Medicaid inpatient hospital reimbursement rates upon hospital cost trends. HRS has used no technical methodology based upon hospital cost trends to develop any of the "percentage allowances." At least since January 1, 1974, HRS's "percentage allowances" have been less than the corresponding average annual increases in the costs incurred by Florida hospitals of providing inpatient hospital services. Prior to March 30, 1976, all of HRS's published regulations addressing reimbursement of participating hospitals for their costs of providing inpatient hospital services to Medicaid patients required HRS to reimburse such hospitals in accordance with Medicare cost reimbursement principles and standards. In certain internal documents, Petitioner's Exhibits P-44 and P-12, HRS states that the average costs of providing inpatient hospital services in the State of Florida rose at least 18 percent during calendar year 1975. In November, 1975, the Secretary of HRS was informed by HRS officials that HRS faced a projected budgetary deficit for its fiscal year ended June 30, 1976. A decision memorandum presented options to the HRS Secretary for reducing the projected deficit. Among such options presented to and approved by the HRS Secretary was to reduce the "percentage allowance" from 9 percent to 6 percent. The reduction of the "percentage allowance" by HRS from 9 percent to 6 percent was effected in response to HRS's projected deficit, and was not based upon an analysis of hospital cost trends. HRS incorporated the 6 percent "percentage allowance" into its administrative rules which were published on March 30, 1976. In response to objections raised by the Florida Hospital Association to the reduction in the percentage allowance by HRS from 9 percent to 6 percent, HRS officials reexamined that reduction. During HRS's reexamination of its previous "percentage allowance" reduction, HRS was aware of and acknowledged the fact that Florida hospital costs were increasing at an average annual rate in excess of both the earlier 9 percent and the resulting 6 percent "percentage allowance." In a memorandum dated September 13, 1976, from HRS official Charles Hall to the Secretary of HRS, Petitioner's Exhibit P-45, Charles Hall informed the Secretary that the methods and standards then used by HRS to reimburse participating hospitals for their costs of providing inpatient hospital services to Medicaid patients was out of compliance with federal requirements. Charles Hall further informed the Secretary that the reason HRS had not theretofore been cited by HEW for noncompliance was the manner in which the Florida State Plan had been drafted, i.e., that the State Plan required HRS to reimburse hospitals under Medicaid for the reasonable costs that they would have been reimbursed applying Medicare cost reimbursement principles and standards. In a letter dated September 20, 1976, Petitioner's Exhibit P-31, HEW informed HRS that HEW had received a complaint from the Florida Hospital Association that the methods HRS was actually using to reimburse hospitals for the costs of providing inpatient hospital services to Medicaid patients were in violation of federal regulation 45 C.F.R. Section 250.30(a). A proposed amendment to Florida's State Plan submitted by HRS to HEW in November, 1976, Petitioner's Exhibit P-49, if approved, would have allowed HRS to reimburse hospitals for the cost of providing inpatient hospital services to Medicaid patients under methods differing from Medicare cost reimbursement principles and standards (an "alternative plan"). "Alternative plans" have been permitted under applicable federal regulations since October 21, 1974. A state participating in the Medicaid program may elect to establish an "alternative plan," but may not implement such "alternative plan" without the prior written approval of HEW. Florida has not had in effect an "alternative plan" of reimbursing participating hospitals for their costs of providing inpatient hospital services to Medicaid patients that was formally approved by HEW at any time prior to July 1, 1981. By letter dated January 7, 1977, Petitioner's Exhibit P-32, HEW notified HRS that it had formally cited HRS for noncompliance with federal regulations governing reimbursement of inpatient hospital services under Medicaid. HRS acknowledged their noncompliance and between November, 1976, and October 30, 1977, HRS attempted to revise its proposed "alternative plan" on at least two occasions in an attempt to obtain HEW approval. In October, 1977, HRS withdrew its proposed "alternative plan" then pending with HEW. HRS then contracted with an outside consultant, Alexander Grant & Company, to assist in the formulation of a new "alternative plan" proposal. In January, 1978, Alexander Grant & Company delivered its draft of an "alternative plan" to HRS. In October, 1978, HRS submitted a draft "alternative plan" to HEW for review and comment, and HEW expected HRS to submit a formal "alternative plan" proposal to HEW for its approval by November 1, 1978. HRS did not submit the formal "alternative plan" proposal to HEW until August 12, 1980. In a letter dated February 21, 1979, from Richard Morris, HEW Regional Medicaid Director, Region IV, to United States Senator Richard Stone of Florida, Mr. Morris advised Senator Stone: For more than two years the Florida Medicaid Program has not met Federal Requirements for inpatient hospital services reimbursement. Their payment methodology under-reimburses certain hospitals year after year. The pros- pective interim per diem rate paid by Florida to hospitals includes a percentage allowance to cover increased costs during the forthcom- ing year that is consistently less than increased costs in some hospitals. If the payments are less than costs, the difference is not reimbursed. This results in underpay- ments. We have worked closely with Florida to develop an acceptable alternative system that would meet Federal requirements. To date, Florida has not implemented such a system despite having received informal HEW agreement on a draft plan developed more than a year ago. It is our understanding that this alternative plan is not a high priority item at this time. We will con- tinue to work with HRS staff to secure Florida compliance regarding this require- ment. Petitioner's Exhibit P-46. Since August 12, 1980, HRS has submitted to HEW for its approval at least four more versions of an "alternative plan." Petitioner's Exhibits P-120, P-121, P-123, and P-152. Each of these versions were approved by the Secretary of HRS, and HRS believes each to comply with applicable Florida law. Mr. Erwin Bodo, Ph.D., was and is the HRS official responsible for the development and drafting of Exhibits P-120, P-121, P-123, and P-152. In June, 1981, HEW approved an "alternative plan" for the State of Florida (Exhibit P-152) , and such "alternative plan" was implemented effective July 1, 1981. Until July 1, 1981, HRS continued to use the 6 percent percentage allowance" to compute inpatient hospital reimbursement under Medicaid. Even after its repeal, Rule 10C-7.39(6), Florida Administrative Code, is applied by respondent in calculating reimbursement for Medicaid services provided between March 30, 1976, and July 1, 1981. From November 20, 1976, until July 1, 1981 the period in which HRS was attempting to secure HEW approval for an alternative plan--HRS was aware that the costs of inpatient hospital services were increasing at an average annual rate in excess of the 6 percent "percentage allowance." From September 1, 1976, through July 1, 1981, HRS has been out of compliance with its approved State Plan provisions, and HEW regulations governing reimbursement for inpatient hospital services under Medicaid because HRS's methods for reimbursing hospitals for the cost of providing those services to Medicaid patients have resulted in a substantial number of hospitals including petitioner--being reimbursed at a lower rate than the hospitals would have been reimbursed applying Medicare cost reimbursement principles and standards. Since the quarter ending December 31, 1976, until July 1, 1981, HEW has formally cited HRS as being in contravention of its approved State Plan provisions, and HEW (now HHS) regulations, governing reimbursement for inpatient hospital services under Medicaid because HRS's methods for reimbursing hospitals for the cost of providing those services to Medicaid patients have resulted in a substantial number of hospitals--including petitioner--being reimbursed at a lower rate than the hospitals would have been reimbursed applying Medicare cost reimbursement principles and standards. PAN AMERICAN HOSPITAL CORPORATION Petitioner, Pan American Hospital Corporation, is a not-for-profit corporation, duly organized and existing under the laws of the State of Florida. Petitioner is a tax-exempt organization as determined by the Internal Revenue Service pursuant to Section 501(c)(3) of the Internal Revenue Code of 1954, as amended. At all times pertinent to this controversy, petitioner has operated and continues to operate a duly licensed 146-bed, short-term acute care general hospital, located at 5959 Northwest Seventh Street, Miami, Florida 33126. At all times pertinent to this controversy, petitioner has been and continues to be a duly certified provider of inpatient hospital services, eligible to participate in the Florida Medicaid program since January 27, 1974. The Appendix to this Final Order is a true and correct copy of the "Participation Agreement" entered into between petitioner and HRS, whereunder, inter alia, petitioner became eligible to receive payment from HRS for covered inpatient hospital services provided to Medicaid patients. At all times pertinent to this controversy, petitioner has been a certified "provider of services" participating in the Medicare program. During the fiscal periods in dispute in this action, petitioner did provide covered inpatient hospital services to Medicaid patients, and became eligible for payment by HRS of its reasonable costs of providing such services, determined in accor- dance with Medicare cost reimbursement principles and standards. With respect to each of the fiscal periods in dispute in this action, petitioner timely filed all cost reports and other financial data with HRS or its contracting agents, including Blue Cross of Florida, Inc., to enable HRS to determine petitioner's reasonable costs of providing covered inpatient hospital services to Medicaid patients. During each of the fiscal periods in dispute in this action, HRS failed to reimburse petitioner for its reasonable costs of providing covered inpatient hospital services to Medicaid patients, determined in accordance with applicable Medicare cost reimbursement principles and standards. Such costs incurred by petitioner were reasonable, necessary, related to patient care, and less than customary charges within the meaning of those Medicare principles and standards. With respect to each of the fiscal periods in dispute, HRS and/or its contracting agent, Blue Cross of Florida, Inc. , reviewed and audited the cost reports filed by petitioner, and as a result of such review and audits set or adjusted, as applicable, the Medicaid inpatient per diem reimbursement rate at which petitioner would be paid during the next succeeding fiscal period or until that rate was again adjusted. MOTION TO DISMISS RULE CHALLENGE DENIED Respondent sought dismissal of petitioner's challenge to Rule 10C- 7.39(6), Florida Administrative Code, on grounds that the challenged rule provision has now been repealed (effective July 28, 1981). By this motion, respondent raises the question whether petitioner remains "substantially affected" notwithstanding the repeal. The parties are in agreement that respondent still applies Rule 10C-7.39(6) , Florida Administrative Code, in calculating reimbursement for providers like petitioner who furnished Medicaid services during the time between adoption of the rule and its repeal. The present case resembles State Department of Transportation v. Pan American Construction Company, 338 So.2d 1291 (Fla. 1st DCA 1976), app. dism. 345 So.2d 427 (Fla. 1977). The rule challenged in that case had been promulgated pursuant to a statute that was later amended by legislation which took effect after the Section 120.56 hearing, but before entry of a final order invalidating the rule. In response to the statutory amendment, moreover, the agency whose rule was under challenge adopted an emergency rule superseding the challenged rule. On appeal, the agency argued that the rule challenge was moot. The court ruled: While normally the law as it exists at the time of review will be applied to a pending case, in this proceeding, begun under the old law and rules adopted pursuant to it, we consider that respondents are entitled to construction of such law and rules. Their rights under contracts with peti- tioner which were in existence during the life of the former statute and rules may be affected by the construction of that statute and the rules adopted pursuant to it. State Department of Transportation v. Pan American Construction Co., 338 So.2d 1291, 1294 (Fla. 1st DCA 1976) In the present case there has been no statutory amendment, but here as in State Department of Transportation v. Pan American Construction Co., the proceedings pursuant to Section 120.56, Florida Statutes, began before the repeal of the challenged rule; and the parties' "rights under contracts . . . which were in existence during the life of the former . . . [rule] may be affected by the construction of that . . . [rule]." 338 So.2d at 1294. Simultaneously with the present proceedings, petitioner and respondent are litigating the question of what moneys, if any, respondent owes petitioner as reimbursement for Medicaid services furnished during periods which include the entire time that Rule 10C- 7.39(6) was in effect. No. 80-112. Even though Rule 10C-7.39(6), Florida Administrative Code, stands repealed, petitioner remains "substantially affected by" the rule, within the meaning of Section 120.56(1), Florida Statutes (1979). MOTION TO DISMISS DENIED Respondent contends that these proceedings are defective "for failure to join an indispensable party," viz., the federal government, because it "is Respondent's intention, should any liability result from this action, to make a claim for federal financial participation as to approximately fifty-nine percent of such liability [See generally] 42 U.S.C. Section 1320b-2(a)(2)." Motion to Dismiss, p. 2. This motion is also addressed to the petition in the companion substantial interest case, No. 80-112, and discussed in the recommended order in that case. For present purposes, it suffices to state the self-evident: No agency can avoid an administrative challenge to a rule it alone has promulgated on grounds that some other party's interest may be adversely affected by invalidation of the rule. CONSTITUTIONAL GROUNDS Among other things, petitioner contends that Rule 10C-7.39 (6), Florida Administrative Code, should be invalidated as violative of state and federal constitutional prohibitions against impairment of contractual obligations. Article I, Section 10 of the Constitution of the State of Florida proscribes "law[s] impairing the obligation of contracts," and the federal constitution also forbids any "State . . . [to] pass any . . . law impairing the obligation of contracts." Article I, Section 10. See United States Trust Co. v. New Jersey, 431 U.S. 975 (1977). Challenges to administrative rules brought pursuant to Section 120.56, Florida Statutes (1979), cannot, however, be predicated on constitutional grounds. State Department of Administration, Division of Personnel v. State Department of Administration, Division of Administrative Hearings, 326 So.2d 187 (Fla. 1st DCA 1976). See Department of Environmental Regulation v. Leon County, 344 So.2d 290, 295 n. 2 (Fla. 1st DCA 1977). INVALID EXERCISE OF DELEGATED LEGISLATIVE AUTHORITY The main thrust of petitioner's challenge to Rule 10C-7.39 (6), Florida Administrative Code, is its contention that respondent adopted the challenged rule not to implement Section 409.266, Florida Statutes, but in an attempt to avoid obligations imposed by Section 409.266, Florida Statutes, and the provisions of federal law incorporated by reference in that State statute. The challenged rule pertains to agreements made between respondent and providers of medical services in accordance with the provisions of Title XIX of the Social Security Act. The statute authorizes respondent to "[e]nter into . . . agreements as may be necessary or needed to implement the provisions of Title XIX of the Social Security Act pertaining to medical assistance." Section 409.266(2)(a) , Florida Statutes (1979). No party suggests that any other State statutory provision furnishes substantive authority for promulgation of Rule 10C-7.39(6), Florida Administrative Code, and the parties have stipulated that "HRS has never been authorized to . . . perform any functions with respect to the Medicaid program that are in contravention of or not authorized by Title XIX of the Social Security Act and implementing Federal regulations and requirements." Agency rules must conform to enabling statutes and may not repeal, amend, or modify any statute. State Department of Health and Rehabilitative Services v. McTigue, 387 So.2d 454 (Fla. 1st DCA 1980); Department of Health and Rehabilitative Services v. Florida Psychiatric Society, 382 So.2d 1280 (Fla. 1st DCA 1980); State Department of Transportation v. Pan American Construction Co., 338 So.2d 1291 (Fla. 1st DCA 1976) app. dism. 345 So.2d 427 (Fla. 1977) Incorporated by reference into Section 409.266, Florida Statutes, was the federal statutory requirement that hospitals providing Medicaid services be reimbursed by respondent for reasonable costs incurred in accordance with an approved State Plan. 42 U.S.C. Section 1396a (a)(13)(B) , Pub. L. 89-97, Section 121(a), redesiquated 42 U.S.C. Section 1396a (a) (13)(D), Pub. L. 90- 248, Section 224(a). At the time of its incorporation into State law, this federal statute had been definitively explicated by federal regulations requiring that reasonable cost for Medicaid purposes be calculated in accordance with applicable Medicare principles for purposes of reimbursing hospitals like petitioner that furnished both Medicaid and Medicare services. 2/ 42 C.F.R. Section 50.30(b), 34 Fed. Reg. 1244 et seq. (January 25, 1969). In addition, all Florida "State Plan provisions . . . approved by HEW and. . govern[ing] HRS's reimbursement of inpatient hospital services prior to July 1, 1981, . . . commit HRS to reimburse hospitals that also participated in the Medicare program for their reasonable costs of providing inpatient hospital services to Medicaid patients, applying Medicare cost reimbursement principles and standards." Pre-hearing Stipulation, 19. Even before adopting Rule 10C-7.39(6), Florida had begun setting Medicaid reimbursement rates by adjusting the previous year's rates upward to reflect inflation, as a matter of policy. As the parties have stipulated, in November of 1975, a budgetary deficit was projected for HRS; and, even though HRS was aware that inflation was substantially higher than 6 percent, HRS eventually decided to promulgate the rule now under challenge, setting the adjustment at 6 percent. HRS promulgated Rule 10C-7.39(6), Florida Administrative Code, not in furtherance of its statutory charge to reimburse Medicaid providers for costs reasonably incurred, but in order expediently to cut its own costs by disregarding the statutory scheme and reimbursing Medicaid providers less than the costs they had reasonably incurred. Cf. Patricia Godboldt v. David Pingree, Secretary, Department of Health and Rehabilitative Services, State of Florida, No. 81-2862 (2d Cir.; Prelim. Inqy., Nov. 25, 1981). UNCODIFIED POLICY CHALLENGED AS RULE Petitioner challenges not only Rule 10C-7.39(6), Florida Administrative Code, but also, as "an illicit rule," HRS's prior practice of setting reimbursement rates by adjusting the previous year's rates. The percentage allowances under preexisting practice were higher (9 and 12 3/ percent) but the methodology was the same as that codified in Rule 10C-7.39(6), Florida Administrative Code. The parties stipulated to the existence of a practice that reflected a policy that changed over time, see McDonald v. Department of Banking and Finance, 346 So.2d 569 (Fla. 1st DCA 1977) , but did not stipulate that this practice reflected a hard and fast "rule." The parties stipulated that "HRS used [12 percent from January 1, 1970, to June 30, 1972, and 9 percent from July 1, 1972, to approximately March 30, 1976] . . . in determining Medicaid reimbursement rates for inpatient hospital services," but did not prove or stipulate to the existence of any formal document or other written statement "issued by the agency head for implementation by subordinates with little or no room for discretionary modification." State Department of Administration v. Stevens, 344 So.2d 290, 296 (Fla. 1st DCA 1977). In the absence of such a stipulation or proof, the agency's practice of requiring a 9 percent "percentage allowance, has not been shown to amount in itself to an illicit rule. Department of Corrections v. McCain Sales of Florida, Inc., 400 So.2d 1301 (Fla. 1st DCA 1981). ATTACHMENT 4.19A Petitioner's challenge to Attachment 4.19A of the Florida State Plan for Medical Assistance was conditioned by the words "to the extent that Attachment 4.19A . . . Is interpreted in a manner different than that set forth in Paragraph 15" of the petition. Since the parties stipulated, in substance, to the allegations of paragraph 15 of the petition, the condition for the challenge never occurred. In any event, it is very clear that Attachment 4.19A did not have the force of a rule, inasmuch as its key pronouncement, viz., that "retroactive adjustments are prohibited by skate statute" was completely disregarded by respondent. Rule 10C-7.39(6), Florida Administrative Code, the policies which preceded that rule, and every contract respondent entered into with providers of Medicaid services contemplated retroactive adjustments. It is, accordingly, ORDERED: The final sentence of respondent's Rule 10C-7.39(6), Florida Administrative Code, is hereby declared to be an invalid exercise of delegated legislative authority. Petitioner's challenge to the percentage allowance policies that preexisted Rule 10C-7.39(6), Florida Administrative Code, is dismissed. Petitioner's challenge to Attachment 4.19A of the Florida State Plan for Medical Assistance is dismissed. DONE AND ENTERED this 4th day of December, 1981, in Tallahassee, Florida. ROBERT T.

The Issue The issue in this case is whether the methodology for grouping hospitals adopted by the HCCB pursuant to Sections 4D- 1.03, 4D-1.12(1) and 4D-1.12(2), F.A.C., constitutes an invalid exercise of delegated legislative authority as being arbitrary or capricious? Mercy has also raised one issue as to whether the grouping methodology is violative of constitutional guarantees of administrative equal protection and due process. This issue, however, is beyond the jurisdiction of the Division of Administrative Hearings.
Findings Of Fact Introduction. The HCCB and Its Hospital Grouping Function. The HCCB was formed pursuant to Part II of Chapter 395, Florida Statutes (1979). The HCCB was created pursuant to the specific authority of Section 395.503, Florida Statutes (1979), in order to further the accomplishment of legislative intent contained in Section 395.5025, Florida Statutes (1984 Suppl.): It is the intent of the Legislature to assure that adequate health care is affordable and accessible to all the citizens of this state. To further the accomplishment of this goal, the Hospital Cost Containment Board is created to advise the Legislature regarding health care costs; inflationary trends in health care costs; the impact of health care costs on the state budget; the impact of hospital charges and third-party reimbursement mechanisms on health care costs; and the education of consumers and providers of health care services in order to encourage price competition in the health care marketplace. The Legislature finds and declares that rising hospital costs and cost shifting are of vital concern to the people of this state because of the danger that hospital services are becoming unaffordable and thus inaccessible to residents of the state. It is further declared that hospital costs should be contained through improved competition between hospitals and improved competition between insurers, through financial incentives which foster efficiency instead of inefficiency, and through sincere initiatives on behalf of providers, insurers, and consumers to contain costs. As a safety net, it is the intent of the Legislature to establish a program of prospective budget review and approval in the event that competition-oriented methods do not adequately contain costs and the access of Floridians to adequate hospital care becomes jeopardized because of unaffordable costs. As a part of its responsibilities the HCCB is required, "after consulting with appropriate professional and governmental advisory bodies and holding public hearings, and considering existing and proposed systems of accounting and reporting utilized by hospitals," to specify a uniform system of financial reporting for hospitals. Section 395.507(1), Florida Statutes Suppl.) to: In order to allow "meaningful comparisons" of data reported by hospitals under the uniform system of financial reporting, the HCCB is required by Section 395.507(2), Florida Statutes (1984 Suppl.) to group hospitals according to characteristics, including, but not limited to, a measure of the nature and range of services provided, teaching hospital status, number of medical specialties represented on the hospital staff, percentage of Medicare inpatient days, average daily census, geographical differences, and, when available, case mix. In providing for grouping of hospital, the HCCB is required to establish ten general hospital groups and additional speciality groups "as needed." Section 395.507(2), Florida Statutes (1984 Suppl.). No hospital group can contain fewer than five hospitals, however. Id. Grouping is to be provided by rule. Id. Pursuant to Section 395.509(1), Florida Statutes (1984 Suppl.), every Florida hospital is required to file its budget with the HCCB for "approval." The budget is required to be filed on forms adopted by the HCCB and based on the uniform system of financial reporting. Section 395.507(6), Florida Statutes (1984 Suppl.). To determine whether a hospital's budget is to be approved, all hospitals in Florida are to be placed in groups. A hospital's budget is then compared to the budgets of the hospitals assigned to its group. Hospital groups for this purpose are established pursuant to Section 395.509(4)(a), Florida Statutes (1984 Suppl.). The provisions of Section 395.509(4)(a), Florida Statutes (1984 Suppl.), are identical to Section 395.507(2), Florida Statutes (1984 Suppl.). In determining whether a hospital's budget is to be approved, Section 305.509(2), Florida Statutes (1984 Suppl.), establishes two initial "screens" which a hospital must meet based upon the hospital's gross revenue per adjusted admission. The term "gross revenue" is defined as: the sum of daily hospital service charges, ambulatory service charges, ancillary service charges, and other operating revenue. Gross revenues do not include contributions, donations, legacies, or bequests made to a hospital without restriction by the donors. Section 395.502(11), Florida Statutes (1984 Suppl.). "Adjusted admission" is defined by Section 395.502(1), Florida Statutes (1984 Suppl.), as: the sum of acute admissions and intensive care admissions divided by the ratio of inpatient revenues generated from acute, intensive, ambulatory, and ancillary patient services to gross revenues. Gross revenues per adjusted admission (hereinafter referred to as "GRAA") is therefore the total hospital ambulatory and ancillary service charges and other operating revenue for all acute and intensive care admissions divided by the ratio of inpatient revenues from acute, intensive, ambulatory and ancillary patient services to gross revenue; or, stated more simply , inpatient revenue per admission. The "screens" which must be met in order for a hospital's budget to be approved upon initial determination are: (1) the hospital's GRAA must not be in the upper 20th percentile of the hospitals within its group; and (2) the rate of increase in a hospital's GRAA as contained in its current budget compared to the hospital's GRAA as reported in its most recently approved budget must not exceed a "maximum allowable rate of increase" if the hospital's GRAA is in the 50th to 79th percentile of the hospitals in its group. If a hospital's GRAA is in the 49th percentile or less of the hospitals in its group, its budget is automatically approved. In determining whether a hospital's GRAA fails the screens, Section 395.509(2), Florida Statutes (1984 Suppl.), provides: Percentile values for gross operating revenue per adjusted admission shall be determined monthly by the board for each group established pursuant to s. 395.507(2) by ranking projected gross operating revenues per adjusted admission contained in the most recently approved or submitted budgets for the hospitals in each group, including any hospital that is contesting its grouping assignment. In determining the applicability of paragraph (a) or paragraph (b), the board shall consider the basis of the projections by the hospital, including consideration of the following factors: any increase in patient admissions caused by the creation of preferred provider organizations or health maintenance organiza- tions, population increases, changes in the hospital case mix or in services offered, changes in technology, or other similar factors. If a hospital's GRAA fails either of the screens (its GRAA is in the upper 20th percentile of its group or its GRAA rate of increase is excessive and its GRAA is in the 50th to 79th percentile of its group) that hospital's budget must be reviewed by the HCCB "to determine whether the rate of increase contained in the budget is just, reasonable, and not excessive." Section 395.509(5), Florida Statutes (1984 Suppl.). Pursuant to Section 395.509(6), Florida Statutes (1984 Suppl.), the HCCB is authorized, if it first determines under Section 395.509(5), Florida Statutes (1984 Suppl.), that the hospital's rate of increase is not just, reasonable and not excessive, to amend or disapprove any hospital's budget which does not meet the two screens of Section 395.509(2), Florida Statutes (1984 Suppl.), to establish a rate of increase which is "just, reasonable, and not excessive." The HCCB's authority under Section 395.509(6), Florida Statutes (1984 Suppl.), applies only if the HCCB first complies with the following pertinent provisions of Section 395.509(5), Florida Statutes (1984 Suppl.): The board shall disapprove any budget, or part thereof, as excess that contains a rate of increase which is not necessary to maintain the existing level of services of the hospital or, if the hospital increases its existing level of services, any amount not necessary to accomplish that increase. In making such deterioration . . . the board shall consider the following criteria: The efficiency, sufficiency, and adequacy of the services and facilities provided by the hospital. The cost of providing services and the value of the services to the public. The ability of the hospital to improve services and facilities. The ability of the hospital to reduce the cost of services. The ability of the hospital to earn a reasonable rate of return. The accuracy of previous budget submissions by the hospital compared to the actual experience of the hospital the The number of patient days reimbursed by Medicare or Medicaid. The number of patient days attributable to the medically indigent. The research and educational services provided by the hospital if it is a teaching hospital. The projected expenditures or revenues for or from construction of facilities or new services which are subject to regulation under s. 381.494 may not be included in the budget of a hospital until the construction or services are approved or authorized by the state health planning agency. The cost of opening a new hospital, for first 3 years. The Challenged Rules. In carrying out its duty to establish a uniform system of financial reporting, the HCCB adopted Section 4D- 1.03, F.A.C., which provides: The Board, pursuant to Section 395.505, Florida Statutes, hereby adopts and establishes a uniform system for hospitals to file the prior year audited actual data report, the interim report of financial and statistical information. This system is described and the forms, instructions, and definitions therefor are contained in the Board's publication entitled Hospital Uniform Reporting System Manual. The Chart of Accounts adopted pursuant to Section 395.507(1), Florida Statutes, and this Chapter 4D-1, and as hereafter modified, shall be utilized by each hospital for submitting the prior year audited actual data report, the interim report and the budget report. In order to determine whether a hospital's budget should be automatically approved under Section 395.509(2), Florida Statutes (1984 Suppl.), the HCCB adopted Section 4D-1.12, F.A.C. Sections 4D-1.12(1) and (2), F.A.C., provide: The staff shall review the budget report based upon the hospital's ranking for gross revenue per adjusted admission within its group and upon its rate of change in gross revenue per adjusted admission in the proposed budget as required in Section 395.507(6), Florida Statutes, and the most recently Board approved budget. As part of the budget report review process, groupings of hospitals shall be established according to the characteristics and methodology as outlined in Chapter V, Section B, Hospital Unit Uniform Reporting System Manual and as outlined in Section 395.507(2), Florida Statutes. Percentile values for gross revenue per adjusted admission shall be determined monthly for each group by ranking projected gross revenue per adjusted admission contained in the most recently approved or submitted budgets for the hospitals in each group, including any hospital that is contesting its grouping assignment. 12. Sections 4D-1.03 and 4D-1.12(1) and (2), F.A.C., are the rules challenged by Mercy. These rules, as quoted herein, were effective as of November 5, 1984. The rules were originally adopted effective June 30, 1980. The rules were amended to their present wording in response to "major" legislation enacted in 1984 which amended Part II, Chapter 395, Florida Statutes (1983), and granted authority to the HCCB for the first time to approve, disapprove or amend hospital budgets under certain circumstances. Chapter 79-106, Laws of Florida. The challenged rules essentially provide that the HCCB, when grouping of hospitals for purposes of the uniform system of financial reporting and for purposes of reviewing and comparing budgets to determine if they should be automatically approved under Section 395.509(2), Florida Statutes (1984 Suppl.), will apply the grouping methodology outlined in Chapter V, Section B of the Hospital Uniform Reporting System Manual (hereinafter referred to as the "Manual"). Section 4D-1.18, F.A.C., also adopted effective November 5, 1984, incorporates by reference the Manual within each rule in Chapter 4D-1, F.A.C., which references the Manual. This rule has not been challenged in this proceeding. The Hospital Grouping Methodology and Its Development. Generally, Chapter V, Section B of the Manual, sets out the objective of the grouping methodology, the procedure for forming groups, a list of the variables considered in forming groups and the weight to be accorded each variable. The goals of the grouping methodology, as provided in the Manual, are to "facilitate comparison of hospitals with similar patient mix and market conditions" and to "develop groups of sufficient size . . . to assure statistically valid comparisons." Based upon the procedure for forming groups contained in the Manual, hospitals are grouped into nine, non-teaching, short-term hospital groups, one Major teaching hospital group and a number of specialty hospital groups. It is the method of grouping hospitals into nine short-term hospital groups which is at issue in this proceeding. Assignment of hospitals to the nine short-term hospital groups is accomplished through the use of the "McQueen's K-means clustering algorithm included in the cluster analysis t computer program package CLAN developed by T.D. Klastorin and Robert Ledingham (June, 1980 version)." A clustering analysis is a method of grouping a set of objects (in this case, hospitals) into relatively homogeneous groups. The goal of a clustering algorithm is to minimize the differences between the members of the group. The objects are grouped based upon a set of variables which are considered significant for purposes of comparing the objects. In order to account for the significance of each variable, the variables are weighted. The variables have a numerical score and after weighing, the weighted sum of the variables for each object is compared and the objects are grouped based upon their variable scores. There are a number of clustering algorithms which can be used to group hospitals. The HCCB chose to use the "McQueen's K-means" clustering algorithm. The use of McQueens K-means clustering algorithm has not bean challenged in this proceeding. Nor does the evidence establish that the selection of McQueen's K-means clustering algorithm is arbitrary and capricious. The clustering algorithm is performed by computer. The computer program utilized by the HCCB to perform the algorithm is called "CLAN" and was developed by T.D. Klastorin and Robert Ledingham. The evidence at the hearing supports a finding that the selection of this computer program is reasonable. Once hospitals are grouped, they are notified of their group designation and allowed to request reconsideration of their group assignment. The request must made within thirty days after notification. Following the creation of the HCCB in 1979, Price Waterhouse & Company was engaged by the HCCB as a consultant to assist in still establishing an appropriate hospital grouping methodology. The HCCB also created an advisory committee to assist the HCCB and Price Waterhouse & Company in developing the grouping methodology. This committee, designated as the Technical Advisory Committee (hereinafter referred to as the "TAC") was comprised of individuals from the hospital industry and academia and certified public accountants. The TAC worked with Price Waterhouse & Company in developing the grouping methodology and the uniform reporting system. Because of time constraints, the TAC's involvement with evaluating the methodology was limited. The HCCB ultimately decided to pattern the grouping methodology it adopted after the grouping methodology then being used by the State of Washington, as recommended by Price Waterhouse & Company. The Washington system was not adopted exactly; a number of changes to Washington's methodology were made to the grouping methodology adopted by the HCCB. Mercy has proposed several findings of fact beginning on page 35 and ending on page 38 of its proposed order concerning the "Differences in Washington Hospital Characteristics and Grouping Methodology Model." Those proposed findings of fact can be and are hereby disposed of by the following finding of fact: because of differences in the hospital industries of the States of Florida and Washington and other differences between the two States, Florida's grouping methodology cannot be justified solely on the basis that Washington's grouping methodology was used as a starting point in developing Florida's grouping methodology. Those differences, however, do not support a finding of fact that Florida's grouping methodology is arbitrary and capricious since the Washington system was not adopted without substantial modifications, including a reduction of Washington's eighteen variables initially to fourteen and ultimately to seven, and the use of unequal weighting of the variables. The TAC reviewed and discussed the grouping methodology initially approved by the HCCB prior to its approval. Some of Mercy's witnesses, who were members of the TAC, indicated during their testimony that the TAC never decided anything because no "vote" was ever taken of TAC members and that the TAC did not advise the HCCB but instead advised the staff of the HCCB. Their testimony in this regard has been given little weight. The fact that no formal "vote" was taken of TAC members does not mean that the TAC did not take a position on matters it discussed. The consensus of the TAC could be, and was, gleaned from its discussions. The staff of the HCCB in fact reported decisions of the TAC to the HCCB verbally and by minutes of TAC meetings. Although the accuracy of staff's reports was sometimes questioned, no question was raised about whether TAC had taken positions. The fact that the HCCB staff reported TAC actions to the HCCB also disputes the testimony to the effect that TAC did not advise the HCCB but instead advised the staff of the HCCB. While it may be true that TAC did not deal directly with the HCCB, its analysis was reported, to the HCCB. The HCCB ultimately adopted rules effective June 30, 1980, which incorporated by reference to the Manual, the general outline of the grouping methodology adopted by the HCCB. The TAC ceased to exist following adoption of the HCCB's initial rules. Two new advisory committees were formed: a Technical Advisory Panel (hereinafter referred to as "TAP") on grouping and a TAP for financial analysis. The grouping TAP was made up of individuals from the hospital industry. The grouping TAP met in November and December of 1980 and reviewed the results of test runs of the grouping methodology initially adopted by the HCCB. The results of the initial run were described as "bizarre." This run used equal weighting of the variables. Equal weighting was abandoned and three to four more test runs were made and reviewed by the grouping TAP. After each run the variable weights were adjusted until the results appeared to be "reasonable." The HCCB also established a committee consisting of members of the HCCB designated as the Research and Development Committee (hereinafter referred to as the "R & D Committee"). The R & D Committee reviewed the results of test runs and also found the final groups reasonable. The HCCB met in January, 1981, and adopted the grouping methodology with the adjusted variable weights arrived at as a result of the test runs for use in establishing hospital groups for use in 1981. The grouping methodology was reviewed every year after its initial adoption in 1980. The methodology was reviewed by the HCCB, HCCB's staff, the TAP's and the R & D Committee each year. Throughout the period from 1980 to the present, criticisms of the grouping methodology have been made. Some of these criticisms were agreed with and others were rejected by the HCCB or its staff. Following review of the grouping methodology by the TAP's and the R & D Committee in 1981, the original fourteen variables were reduced to eight. In January, 1982, the weight of one of the variables was changed and one variable was replaced by another variable. In December, 1982, a variable was deleted; seven variables remained. In 1983, clustering analysis was limited in its application to the formation of short-term acute care general hospital groups. In 1984, following the significant amendment of Chapter 395, Florida Statutes (1983), the HCCB adopted the present challenged rules. The rules were effective November 5, 1984. The only change in the grouping methodology approved by the HCCB was the substitution of the Florida price level index variable for percent of population over age 65. The weight assigned to the Florida price level index was the same as the weight that had been assigned to the percent of population over age 65. The changes made to the grouping methodology in 1984 were first suggested by the staff of the HCCB to the grouping TAP in June of 1984. The grouping TAP met on July 11, 1984 and considered and discussed the proposed changes. A number of problem areas were discussed. Although no test run results were presented at this TAP meeting, they were provided to TAP members before the HCCB adopted the grouping methodology changes. Concerns about the geographic or exogenous variables expressed at the grouping TAP meeting suggested a belief that too much or too little emphasis was being placed on geographic considerations. Mercy has proposed a number of findings of fact beginning on page 33 and ending on page 35 of its proposed order concerning the significance of the changes made by the Legislature in 1984 to Part II of Chapter 395, Florida Statutes (1983). Those proposed findings of fact essentially deal with the fact that the powers of the HCCB after the 1984 amendments may have a more significant impact on hospitals and that, therefore, the grouping methodology is of greater interest to hospitals. Mercy's proposed findings of fact are not, however, relevant in determining whether the challenged rules are arbitrary and capricious. The fact that the effect of the grouping methodology on a hospital may now be different does not mean that the use of the grouping methodology, as modified after the 1984 legislative changes to the law, which was developed when the purpose of grouping was different, is not an appropriate methodology. The evidence does not support such a conclusion. Therefore, to the extent that Mercy's proposed findings of fact under Section II, A, of its proposed order have not already been made, they are rejected as unnecessary. Mercy and the HCCB have proposed findings of fact as to whether Mercy has ever questioned the HCCB's grouping methodology since it was first adopted prior to instituting this proceeding. Those proposed findings of fact are not deemed relevant in determining whether the grouping methodology is arbitrary and capricious. If the grouping methodology is in fact arbitrary and capricious, the fact that Mercy did not challenge the methodology when it was first adopted will not make it any less arbitrary and capricious today. Mercy's Challenge. A. Introduction. Mercy is a not-for-profit, general acute care hospital with 550 licensed beds located in Dade County, Florida. Mercy has raised a number of points in this proceeding and its proposed order in challenging the rules in question. All of those points, according to Mercy, prove that the rules are an invalid exercise of delegated legislative authority. In determining whether the facts support such a conclusion, the following standard must be kept in mind: [I]n a 120.54 hearing, the hearing officer must look to the legislative authority for the rule and determine whether or not the proposed rule is encompassed within the grant. The burden is upon one who attacks the proposed rule to show that the agency, if it adopts the rule, would exceed its authority; that the requirements of the rule are not appropriate to the ends specified in the legislative act; that the requirements contained in the rule are not reasonably related to the purpose of the enabling legislation or that the proposed rule or the requirements thereof are arbitrary or capricious. A capricious action is one which is taken without thought or reason or irrationally. An arbitrary decision is one not supported by facts or logic or despotic. Administrative discretion must be reasoned and based upon competent substantial evidence. Competent substantial evidence has been described as such evidence as a reasonable person would accept as adequate to support a conclusion. Agrico Chemical Company v. State, Department of Environmental Regulation, 365 So.2d 759, 763 (Fla. 1st DCA 1978), cert. denied, 376 So.2d 74 (1979). Additionally, the following must be kept in mind: The well recognized general rule is that agencies are to be accorded wide discretion in the exercise of their lawful rulemaking authority, clearly conferred or fairly implied and consistent with the agencies' general statutory duties. . . . An agency's construction of the statute it administers is entitled to great weight and is not to be overturned unless clearly erroneous. . . . Where, as here, the agency's interpretation of a statute has been promulgated in rulemaking proceedings, the validity of such rule must be upheld if it is reasonably related to the purposes of the legislation interpreted and it is not arbitrary and capricious. The burden is upon petitioner in a rule challenge to show by a preponderance of the evidence that the rule or its requirements are arbitrary and capricious. . . . Moreover, the agency's interpretation of a statute need not be the sole possible interpretation or even the most desirable one; it need only be within the range of possible interpretations. Department of Professional Regulation v. Durrani, 455 So. 2d 515, 517 (Fla. 1st DCA 1984). The witnesses who testified in this proceeding who were accepted as experts were qualified in a number of different areas. Those witnesses qualified as experts in statistical analysis or related areas and health care finance rendered opinions as to the appropriateness of the HCCB's grouping methodology. The method of grouping hospitals adopted by the HCCB is a statistical method. Therefore, the determination of whether the HCCB's methodology is arbitrary and capricious depends largely upon whether the methodology is statistically sound. Mercy and the HCCB therefore presented the testimony of witnesses qualified in the area of statistics: Rick Zimmerman, Ph.D., an expert in statistical analysis and social science statistics (for Mercy), and Duane Meeter, Ph.D., an expert in economics and applied statistical analysis and Frank Fox, Jr., Ph.D., an expert in applied statistics (for the HCCB). All three witnesses were knowledgeable and credible. Dr. Zimmerman testified that the HCCB's grouping methodology was "clearly inappropriate." Dr. Zimmerman's opinion was based upon a three step analysis in which he determined: (1) whether the variables selected by the HCCB are appropriate; (2) whether the weights assigned to the variables by the HCCB are appropriate; and, (3) the effect changing the variables and/or weights would have on hospital groups. The results of Dr. Zimmerman's analysis, which formed the basis for his opinion that the HCCB's grouping methodology is not appropriate, are discussed, infra. Mercy has proposed a number of findings of fact in its proposed order concerning the credibility of Dr. Meeter's and Dr. Fox's testimony. Some of those proposed findings of fact have been considered in determining the weight given to their testimony. Both Dr. Meeter and Dr. Fox were, however, knowledgeable and credible. In addition to the opinion of its statistical expert, Mercy presented the testimony of three witnesses who were accepted as experts in health care finance: Messrs. Lawrence R. Murray, Jerry A. Mashburn and Anthony Krayer. All three are certified public accountants. All testified that it was his opinion that the HCCB's grouping methodology was arbitrary. The bases for their opinions are discussed, infra. Selection of "Seed" Hospitals. In order to use a clustering algorithm, a starting point is needed; the first object (hospital) to be placed in each group must be selected. The first objects selected are called "seed" objects. Mercy has attached the HCCB's method of selecting the nine "seed" hospitals in initially performing the McQueen's K-means clustering algorithm. Mercy has proposed the following findings of fact with regard to this point: While none of the parties challenged the use of McQueen's and the CLAN program, no support was offered during the hearing for the method by which the HCCB had selected the nine seed hospitals as initial clustering points. The HCCB's own statistician criticized the HCCB's selection method. The Rankis-Zimmerman report indicates that the final groupings based upon the HCCB's seed hospitals were vastly different than groupings based upon the utilization of seed hospitals selected on a statistical basis. Both the HCCB's and Mercy's statisticians proposed statistically sound methods for selecting seed hospitals, which had not been employed by the HCCB in the Grouping Methodology. [Citations omitted] These proposed findings of fact are not relevant to this proceeding. The burden is on Mercy to show that the selection of "seed" hospitals was arbitrary and capricious; the HCCB is not required to show "support" for its method of selecting the seed hospitals. Additionally, whether there are other methods of selecting seed hospitals is not the test. The HCCB's interpretation of the statute need not be the sole interpretation or even the most desirable one; it only needs to be within the range of possible interpretations. Durrani, supra. Therefore, even if the Rankis-Zimmerman report does indicate that the final groupings of hospitals of the HCCB were vastly different than groupings based upon other methods of selecting seed hospitals, it does not automatically follow that the HCCB's method of selecting seed hospitals was not "within the range of possible interpretations. The weight of the evidence does not prove that the HCCB's method of selecting seed hospitals was arbitrary and capricious. Selection of the Variables. In delegating legislative authority to the HCCB to establish a grouping methodology, the Legislature provided that the following relevant characteristics are to be taken into account: A measure of the nature and range of services provided; Number of medical specialties represented on the hospital staff; Percentage of Medicare inpatient days; Average daily census; Geographic differences; and Case mix, "when available." In response to the Legislature's mandate, the HCCB has adopted seven variables or characteristics. The variables selected by the HCCB include five hospital- specific (endogenous) variables and two geographic (exogenous variables). The variables are as follows: Endogenous Variables: Average occupied beds. Available services. Physician mix. Number of residents. Percent Medicare days. Exogenous Variables: Florida price level index. Personal income. The following findings of fact are made with regard to each of the specific characteristics required to be taken into account by the Legislature and the variables adopted by the HCCB: 1. A measure of the nature and range of services provided. The HCCB has provided in the Manual that "available services" or a service index will be considered. The specific services considered are listed on Table B, Chapter V, of the Manual. Table B also weights or provides a score for each of the various services listed. Each hospital gets the specified score if it has a particular service available. The available services listed are based upon a survey of hospital administrators and chief financial officers in New York, New York, made in the 1970's. Problems with the list of available services have been pointed out to the HCCB and its staff. The primary problem is that the volume of services provided is not taken into account. The problems with the service index, however, relate to the fact that the service index is a proxy for case mix. To date, there is no alternative available which would be a better proxy for case mix. The Legislature contemplated this fact by providing that a measure of the services provided by a hospital will be considered and that case mix will be taken into account "when available." Therefore, while there are "problems" with the service index, consideration of available services is mandated by the Legislature and there are no acceptable alternatives available use for by the HCCB. 2. Number of medical specialties represented on the hospital staff. 52. The HCCB has provided that a physician specialties mix be considered in grouping hospitals. This physician specialties mix is based upon a list of twenty- six specialties for which a hospital gets a single credit for each specialty available regardless of the number of physician specialists available in each specialty or the volume of patients admitted by a physician. 52. Like the service index, the physician specialties mix is a proxy for ease mix and has problems associated with its use. Also like the service index, consideration of this factor is mandated and there are no acceptable alternatives available for use by the HCCB. 3. Percentage of Medicare inpatient days. 53. The HCCB has provided that "percentage Medicare days be considered in grouping hospitals. Consideration of this variable has not been shown to be arbitrary and capricious. 4. Average daily census. 53. The HCCB has provided that "average occupied beds" is to be considered in grouping hospitals. It does not appear that this variable's use was proper, as discussed, infra. 5. Geographic differences. The HCCB has provided that geographic differences be considered in grouping hospitals by providing for the inclusion of the Florida price level index, by county, and median income, by county, as variables to be considered. The only thing that the evidence established with regard to these variables was that they are not "very good" predictors, that "if" they are intended as a measure of input prices they are "poor substitutes," and that there may be "better" measures of the cost of doing business. The evidence does not, however, show that the use of these variables is arbitrary and capricious. Mercy has proposed a number of findings of fact concerning geographic influences in part II, H of its proposed order. The proposed findings of fact begin on page 29 and end on page 33. Most of these proposed findings of fact are not made in this Final Order because they are not deemed relevant or material and are unnecessary to the resolution of this proceeding. The proposed findings of fact contained in part II, H of Mercy's proposed order purportedly show that the HCCB has inadequately accounted for geographic influences. The evidence does establish that the financial characteristics of Florida hospitals and GRAA are affected by the geographic location of a hospital. This is especially true in Florida because of the impact on parts of the State from tourism, language barriers, the number of elderly residents, the available labor markets, and competition. It is also true that the combined weights of the two geographic variables the HCCB has selected for consideration in the grouping methodology--the Florida price level index and median income--is only one-seventh of the combined weights of all the HCCB's variables. It is also true that the grouping methodology results in hospitals from different areas of the State being grouped together, i.e., Mercy's hospital group includes twenty- three hospitals, four of which are located in Dade County and three of which are located in Escambia County. It does not necessarily follow, however, that the HCCB has been arbitrary and capricious in designating only two variables to take into account geographic differences between hospitals. The evidence also does not support a conclusion that it was not proper for the HCCB to limit the weight of the geographic variables to one-seventh of the total weight of the variables. Nor does the evidence demonstrate that the inclusion of hospitals from different areas of the State in the same group is not a proper result just because geographic influences are important. The fact that a large percentage of Dade County and south Florida hospitals do not qualify for automatic approval of their budgets under Section 395.509(2), Florida Statutes (1984 Suppl.), because they are in the upper 20th and the upper 50th to 79th percentiles does not necessarily prove that geographic influences have not been adequately accounted for either, as suggested be Mercy on page 30 of its proposed order. The evidence simply does not support such a conclusion. Nor does it necessarily follow that because Dade County hospitals are "efficient" in the minds of some of Mercy's witnesses and yet are unable to achieve automatic approval of their budgets that the grouping methodology does not adequately account for geographic influences, as suggested by Mercy on pages 30 and 31 of its proposed order. First, the Legislature has provided that factors other than geographic differences are to be considered, which the HCCB has provided for. It may therefore be that some Dade County hospitals do not achieve automatic approval of their budgets because of the other variables. The fact that not all Dade County hospitals fail to achieve automatic approval of their budgets supports such a conclusion. Also, even though a hospital's budget is not automatically approved it does not necessarily mean that it is considered inefficient. If that were the case, its budget would probably be subject automatically to amendment or disapproval. That is not the case. If a hospital's budget is not automatically approved its budget is subject to further review under Section 395.509(5), Florida Statutes (1984 Suppl.). It may still be determined that the hospital is "efficient" based upon this review. The Legislature, in enacting Part II of Chapter 395, Florida Statutes, did indicate that it intended to promote competition and efficiency among hospitals in order to contain hospital costs. Section 395.5025, Florida Statutes (1984 Suppl.). The grouping methodology and, in particular, the comparison of hospitals' GRAA under Section 395.509(2), Florida Statutes (1984 Suppl.), does not alone achieve that intent. Therefore the opinion of several of Mercy's witnesses that Dade County hospitals and in particular, Mercy, are efficient does not support a conclusion that the methodology is arbitrary and capricious or that geographic influences are not adequately considered. On pages 31 and 32 of its proposed order, Mercy suggests that Dade County hospitals only compete with other Dade County hospitals and therefore grouping hospitals from all sections of the State is illogical. In support of this suggestion, Mercy proposes findings of fact to the effect that the HCCB has recognized that consumers are interested in comparing hospital charges on a regional basis and has provided information about hospital cost on a county-by- county basis in the past. Mercy's proposed findings of fact are not accepted for essentially the same reasons that its proposed findings of fact with regard to the efficiency of hospitals were rejected. These proposed findings of fact do not support a finding that the HCCB's grouping methodology is arbitrary and capricious or that geographic differences have not been adequately taken into account. Mercy's has also proposed findings of fact with regard to geographic differences to the effect that after the Legislature specifically required that "geographic differences" be considered in an amendment to Chapter 395, Florida Statutes (1981), in 1982, the HCCB has not added any additional geographic factors to be considered. Although no additional geographic variables have been added, geographic variables have been reviewed and have been changed since 1982. More importantly, these proposed findings of fact do not prove that the existing variables are not adequate. 6. Case Mix. 66. Case mix is to be taken into account "when available." The evidence does not establish that case mix is available at this time. 7. Other variables. The HCCB is not limited to a consideration of the factors which the Legislature specifically provided are to be considered. Sections 395.507(2) and 395.509(4)(a), Florida Statutes (1984 Suppl.). The only other variable the HCCB has provided for consideration is "number of residents." No evidence of significance concerning this variable was presented at the hearing. There was testimony at the hearing that there are other variables which would be appropriate for consideration in grouping hospitals. The evidence does not, however, establish that failure to consider other variables means that the grouping methodology adopted by the HCCB is arbitrary and capricious. Dr. Zimmerman opined that he had determined that the variables selected by the HCCB were not appropriate. Dr. Zimmerman based his opinion upon the fact that he had conducted a "multiple regression analysis." According to Dr. Zimmerman, a "multiple regression analysis is a statistical procedure used to evaluate the relationship of a given set of independent, predictor variables (the HCCB's seven variables) to a single dependent variable (GRAA)." Based upon his application of multiple regression analysis, Dr. Zimmerman concluded that three of the variables used in the HCCB's grouping methodology are not statistically significant predictors of GRAA: available services, average occupied beds and median income. Two of these variables (available services and average occupied beds) are required by Sections 395.507(2) and 395.509(4)(a), Florida Statutes (1984 Suppl.), to be taken into account in the grouping methodology. These Sections also require that geographic factors, which median income is, be taken into account. This does not, however, mean that median income must be included as a variable by the HCCB. Dr. Meeter testified that the statistical significance of the HCCB's variables can be determined by the use of "log transformation." Based upon Dr. Meeter's use of log transformation, median income and available services are statistically significant variables; average occupied beds is not statistically significant. Although the HCCB was required to include "average daily census" as a factor in grouping hospitals, the HCCB was not required to use "average occupied beds." Based upon Dr. Zimmerman's and Dr. Meeter's testimony, the use of average occupied beds as a variable was not proper. Whether the use of available services and median income as variables was proper depends upon whether log transformation is a proper method of determining the statistical significance of variables. Although the evidence on this question was in conflict, it appears that the use of log transformation was proper. The inclusion of available services and median income is therefore not arbitrary and capricious. A second problem with the variables used by the HCCB suggested by Dr. Zimmerman involves the correlation between the seven predictor variables or "multicollinearity." The existence of multicollinearity can invalidate a clustering program. Dr. Zimmerman determined that the correlation between the physician mix, available services and average occupied beds variables and between the Florida price level index and median income variables is large enough that there is a "potential" problem. Dr. Zimmerman's determination that there is a "potential" problem was made through two techniques. He first used "paired correlation." Based upon paired correlation, Dr. Zimmerman used a "rule of thumb" that a paired correlation of 0.7 or higher should be looked at closer. Finding a paired correlation between physician mix, available services and average occupied beds of .74 and between the Florida price level index and median income of .71, Dr. Zimmerman then calculated "R squared" to determine if a potential problem did in fact exist. Dr. Zimmerman indicated that the calculation of R squared is the most highly recommended method of determining if multicollinearity is a problem but agreed there are other methods of making such a determination. Dr. Meeter indicated that Dr. Zimmerman's rule of thumb that based upon paired correlations of 0.7 or higher indicates the problem should be looked at more closely is too strict. Other than Dr. Zimmerman's "experience" (which according to Dr. Zimmerman, consisted of a class he took), Dr. Zimmerman did not cite any authority which supported his rule of thumb. The only other source Dr. Zimmerman referred to--the "SPSS" manual--only indicates that the .82-1.0 range indicates that extreme collinearity exists. Another problem raised by Dr. Meeter with Dr. Zimmerman's conclusions as to multicollinearity, involves the use of "variance inflation factors" (hereinafter referred to as VIF is another technique used by statisticians to determine if multicollinearity is a problem. Dr. Zimmerman did not look at VIF. VIF can be determined by transforming R squared: VIF 1/1- R2. A VIF in excess of 5 or 10 is an indication that multicollinearity exists. One source quoted by Dr. Meeter even indicates that a much higher VIF is necessary to conclude that multicollinerity exists. Transforming Dr. Zimmerman's R squared calculations indicates that VIF is in excess of 5 in only one instance. As discussed more fully, infra, Dr. Zimmerman used a number of alternative methods of grouping hospitals which he designated as "Schemes." Based upon Dr. Zimmerman's "Scheme 3," Dr. Zimmerman found an R squared value of .819. The VIF for an R squared value of .819 is in excess of 5. Scheme 3, however, is not an application of the HCCB's grouping methodology; it is a grouping methodology in which the variables are assigned different weights. As indicated by Dr. Meeter, the weights used in grouping can effect the correlation of the variables. Therefore, the fact that Scheme 3 indicates a possible multicollinearity problem does not prove that multicollinearity is in fact a problem with the HCCB's grouping methodology. Based upon the foregoing it is found that multicollinearity does not exist sufficiently to conclude that the variables used by the HCCB are arbitrary and capricious. Dr. Zimmerman only testified that there was a "potential" problem. Additionally, although multicollinearity may invalidate a clustering program, the evidence does not prove that the HCCB's clustering program is in fact invalid because of any existing "potential" problem. In light of the foregoing findings of fact, it is clear that the HCCB's variables are appropriate with the exception of average occupied beds. The fact that this one variable is not statistically significant, however, does not by itself support a finding that the grouping methodology is inappropriate. The Lack of Testing of the Grouping Methodology. A third point raised by Mercy is entitled "Lack of Testing" in its proposed order and includes several proposed findings of fact on pages 17 and 18 of Mercy's proposed order. Mercy has essentially proposed findings of fact that: (1) it had been recommended to the HCCB when it originally adopted its grouping methodology in 1980 that a statistician be hired to test the grouping methodology; (2) that the failure to do so had been criticized in the past; that it had been recommended that the HCCB obtain assistance of individuals knowledgeable in Florida hospital characteristics to evaluate the grouping process but had failed to do so; (4) that the HCCB had not, until just prior to the hearing of this case, hired a statistician; (5) that the HCCB has not used multiple regression analysis or within-cluster co- variance weighting; and, (6) that the State of Washington's State Hospital Commission has employed a statistician to test its methodology and has effectively been advised by individuals knowledgeable with Washington's hospital characteristics. These proposed findings of fact do not establish that the grouping methodology adopted by the HCCB is arbitrary and capricious even if they were all correct findings of fact. All that these proposed findings of fact show is that the HCCB may not have gone about the adoption of its grouping methodology in the most appropriate manner. Any such shortcomings, based upon 20/20 hindsight, in the manner in which the methodology was adopted do not prove that the grouping methodology itself is not appropriate. Additionally, the evidence does not support all of these proposed findings. In particular, as was discussed, supra, the HCCB did in fact look to individuals knowledgeable in Florida hospital characteristics to evaluate its grouping methodology. The Weight of the Variables. The most significant and troublesome challenge made by Mercy to the HCCB's grouping methodology involves the weights assigned to the variables considered in grouping hospitals. The weights assigned by the HCCB to the seven HCCB variables are: Variable Weight Endogenous: Average occupied beds. 1.0 Available services. 2.0 Physician mix. 0.5 Number of residents. 0.5 Percent Medicare days. 2.0 Exogenous: Florida price level index. 0.5 Personal income. 0.5 The determination of whether the weights selected by the HCCB are arbitrary and capricious depends largely upon the evidence presented at the hearing by those witnesses knowledgeable in the field of statistics. Three witnesses were qualified as experts in statistically related fields. All three were well qualified in their fields and were credible and persuasive. According to Dr. Zimmerman, "the weights used currently by the HCCB are clearly inappropriate." In Mercy exhibit 17, Dr. Zimmerman reaches the following conclusion with regard to the HCCB's variable weights: These weights clearly do not reflect the relationship of the various variables to GRAA and thus appear as arbitrary and inappropriate for use in clustering hospitals on the basis of cost-related variables. Dr. Zimmerman's opinion is based upon the use of "multiple regression analysis," which, according to Mercy exhibit 17, "assesses the relationship of each of the predictor variables to the dependent measure (GRAA)." The evidence, however, does not support a finding of fact that multiple regression analysis is the only statistically valid method of establishing weights to be used in clustering analysis. In fact, there are a number of statistically valid methods of establishing variable weights. One of those acceptable methods is the "subjective" method which was used by the HCCB. Doctors Meeter and Fox substantiated this finding of fact. The use of the subjective method involves the participation of individuals knowledgable in the Florida hospital industry in reviewing and commenting on the weights used. The evidence clearly supports a finding that individuals with such knowledge participated in the process of developing the HCCB's grouping methodology including the selection of variable weights. Even one of Mercy's witnesses provided testimony which supports this conclusion: Mr. Kenneth G. McGee testified that "[i] t was just a trial and error process of changing weights until we ended up with something that people considered more reasonable than what had been produced in the past." Mercy has questioned Dr. Meeter's testimony with regard to the use of the subjective method of weighting variables based upon a number of proposed findings of fact. First, Mercy has proposed findings of fact to the effect that Dr. Meeter indicated that the subjective method is "bad" if not carefully applied. What Dr. Meeter actually said was that any method should be applied carefully. Secondly, Mercy has proposed a finding of fact that in a book relied upon by Dr. Meeter in rendering his opinion about the subjective method--John Hardigan's 1975 book, Clustering Algorithms--the author describes the subjective method as an "unsatisfactory" one. What Dr. Meeter's testimony proves is that Hardigan's comment was a tongue- in-cheek comment that there are several appropriate methods of weighting variables all of which are unsatisfactory, including regression analysis (used by Dr. Zimmerman) and the subjective method (use by the HCCB). Dr. Meeter also relied upon other statistical literature in rendering his opinion as to the use of the subjective method in determining variable weights. Finally, Mercy has suggested that Dr. Meeter did not undertake any independent "statistical" analysis which would support his opinions. Based upon the nature of Dr. Meeter's testimony, it does not appear that such a statistical analysis is a prerequisite to concluding that the use of the subjective method is an acceptable method of determining variable weights. Mercy has proposed a finding that the subjective method of weighting is inappropriate based upon Dr. Zimmerman's testimony. Dr. Zimmerman was asked the following questions and gave the following responses concerning the subjective method: Q Now, in your understanding of how the Board arrived at its weights, is it your opinion that that is totally inappropriate methodology for clustering? Yes or no or maybe? A I am looking to counsel for counsel here. MR. PARKER: Do you understand the questions? THE WITNESS: I do understand the question. And let me give you my full answer as I best understand it. The weights -- and I think what I have commented on at great length -- the weights used by the Hospital Cost Containment Board are clearly on statistical grounds inappropriate. There's no question about that. BY MR. COLLETTE: Now, on these clustering grounds, you testified as to your familiarity with clustering grounds, on clustering grounds, are they totally inappropriate? A If the question is -- I wouldn't say that. Hearing that there is no objection, I will continue. I would rule out the use of a purely subjective weighting scheme as a final solution for cluster analysis. I think it might be one that would be considered at a very early step, but never used, as kind of a preliminary idea. However, I would clearly rule out the use of a purely subjective weighting scheme as something to be proud of and actually put into application. So, if that means yes to your question, I guess yes in that specific way. Dr. Zimmerman's responses are not totally clear with regard to whether the subjective method is, in his opinion, an acceptable method of determining variable weights. Nor would his response, if totally clear, overcome the weight of the evidence in support of a conclusion that the HCCB's method of determining variable weights is not arbitrary and capricious. Alternative Methods of Grouping Hospitals. Mercy has proposed a number of findings of fact under a section of its proposed order entitled "Alternative Variables and Weights Indicated by Statistical Analyses." Pages 22 to 29 of Mercy's proposed order. Some of the proposed findings included therein have been dealt with in other portions of this Final Order, including those findings of fact dealing with the use of multiple regression analysis and multicollinearity. In Dr. Zimmerman's report (Mercy exhibit 17) and during his testimony a number of alternative methods of grouping hospitals were tested and evaluated. Dr. Zimmerman concluded that a number of these alternative methods would be preferable to the methodology adopted by the HCCB. Dr. Zimmerman tested twelve different methods (referred to as "Schemes" by Dr. Zimmerman): the HCCB's, the State of Washington's and ten other methods which used some or all of the seven variables designated by the HCCB. Scheme 3 used all seven variables selected by the HCCB but with different weights. Dr. Zimmerman rejected this scheme because of multicollinearity. In Scheme 4, Dr. Zimmerman used only the four variables which he found to be statistically significant: physician specialties mix, number of residents, percent Medicare days and the Florida price level index. Dr. Zimmerman recognized that this Scheme was not acceptable because of the statutory mandate as to the types of factors which must be taken into account. In order to recognize the requirement of Sections 395.507(2) and 395.509(4)(a), Florida Statutes (1984 Suppl.), that certain variables be taken into account and to alleviate the purported multicollinearity problem, Dr. Zimmerman combined the variables he considered highly correlated into two "scales." "Scale 1" combined physician specialties mix, available services and average occupied beds and "Scale 2" combined the Florida price level index and median income. The weights assigned to these scale were based upon the weights Dr. Zimmerman felt were more appropriate as discussed, supra. Dr. Zimmerman then used multiple regression analysis and a variety of combinations of variables and Scales in Schemes 6-12. Of these Schemes, Dr. Zimmerman testified that Schemes 6 and 10 were preferable, if Scheme 4 could not be used. Scheme 6 involved the use of all of the variables: percent Medicare days, number of residents and Scales 1 and 2. Scheme 10 involved the use of all of the variables except median income: percent Medicare days, number of residents, the Florida price level index and Scale 1. Dr. Zimmerman compared the results of using the HCCB's grouping methodology to the results from using Schemes 3,4,6 and 10. The results showed that more Dade County hospitals had GRAA's, in comparison to the hospitals in the resulting groups under Schemes 3,4,6 and 10, which would result in automatic approval of their budgets than under the HCCB's methodology. Mercy's position within its group also improved as a result of using Schemes 3,4,6 and 10. These proposed findings of and Mercy's proposed findings of fact concerning alternatives considered by Dr. Meeter do not prove that the HCCB's grouping methodology is arbitrary and capricious. As found, supra, six of the seven variables selected by the HCCB are reasonable. The weights assigned to those variables have also been found to be reasonable and Mercy's suggested findings of fact with regard to multicollinearity have been rejected. Mercy has failed to prove that the HCCB's grouping methodology is arbitrary and capricious. Therefore, any alternative methods or Schemes and the results of using such methods cannot and do not overcome such findings. Conclusions. Based upon the foregoing, it is clear that the bases for the opinions that the HCCB's grouping methodology is inappropriate are not supported by a preponderance of the evidence. Dr. Zimmerman's opinion, which was based upon a number of conclusions, was only supported by the fact that one of the variables selected by the HCCB is not proper. The evidence, however, does not support a finding that this fact alone means that the grouping methodology adopted by the HCCB is inappropriate. The facts do not support a conclusion that the grouping methodology adopted by the HCCB is arbitrary and capricious.
Findings Of Fact The PROVIDER received the Final Audit Report that gave notice of PROVIDER'S right to an administrative hearing regarding the alleged Medicaid overpayment. The PROVIDER filed a petition requesting an administrative hearing, and then caused that petition to be WITHDRAWN and the administrative hearing case to be CLOSED.
