The Issue The issue for determination is whether Respondent must repay Petitioner an amount of up to $144,471.25 in alleged Medicaid overpayments, for paid claims covering the period from January 1, 2010, to December 31, 2012.
Findings Of Fact AHCA is the agency responsible for administering Medicaid in the state of Florida. VMC was, at all relevant times, an enrolled Medicaid provider authorized to receive reimbursement for covered goods and services rendered to Medicaid beneficiaries. Exercising its statutory authority to oversee the integrity of Medicaid, the Agency conducted a review of VMC's medical records to verify that claims paid by Medicaid during the period from January 1, 2010, to December 31, 2012 (the "Audit Period"), had not exceeded authorized amounts. During the Audit Period, VMC had submitted claims for 9,783 discrete billable goods or services ("BGOSs") rendered to 1,313 patients (or recipients), on which Medicaid had paid a total of $459,572.82. Rather than examine the records of all 1,313 recipients served, the Agency selected a sample of 35 patients, whose records were reviewed first by a nurse consultant, and then by a physician "peer reviewer." VMC had submitted claims for 302 BGOSs during the Audit Period in connection with the 35 patients in the sample population. Medicaid had paid a total of $13,909.94 on these claims. The Agency's reviewers determined that, for various reasons, VMC had received a total of $6,901.64 in reimbursement of claims in the sample for services not covered by Medicaid, in whole or in part. Having discovered this alleged "empirical overpayment" of $6,901.64, the Agency employed a statistical formula for cluster sampling——for purposes of which a "cluster" comprises all claims relating to an individual patient in the sample population——to ascertain the alleged "probable total overpayment" that VMC had received from Medicaid for the 9,783 BGOSs presented in the totality of claims submitted during the Audit Period.1/ The statistical analysis revealed a probable total overpayment of $179,660.46, with a 95 percent probability that the actual overpayment is equal to or greater than such amount. (As discussed below, VMC disputes the cluster sampling methodology that AHCA used in determining the probable total overpayment based on the empirical overpayment associated with the sample population.) Shortly before the final hearing, based on documents which VMC belatedly produced, the Agency revised its preliminary adjudication of certain claims associated with four of the patients in the sample population, resulting in a reduction of the alleged empirical overpayment to $5,976.00. AHCA's statistical formula extended this figure to VMC's entire patient population for the Audit Period, calculating a total probable overpayment of $144,471.25. VMC does not dispute every one of AHCA's preliminary adjudications. To begin, for five recipients (Patient Nos. 15, 17, 19, 21, and 28) AHCA found no overpayments. Thus, none of the claims presented for BGOSs furnished to these patients is in dispute. In many additional instances, VMC agrees not only with the Agency's determination that Medicaid paid too much for a particular BGOS (or "encounter" as VMC refers to an individual good or service for which a claim was submitted), but also with the amount of the alleged overpayment. As a result of these admissions, none of the claims presented for BGOSs furnished to Patient Nos. 2, 9, 11, 13, 16, 25, and 34 is in dispute. In some instances, VMC suggests that the empirical overpayment for a particular BGOS should be more than the amount that AHCA has alleged. The sum of these suggested additional overpayments ("SAOs") is $303.19. Owing to VMC's inculpatory suggestions of insufficiently aggressive recoupment, it is undisputed that all of the overpayments AHCA has alleged in connection with the claims submitted for the treatment of Patient Nos. 3, 10, 23, 24, 26, and 32 are, in fact, overpayments. In sum, out of 35 patients in the sample population, only 17 involve one or more disputed encounters, where the existence of an overpayment must be decided. As for the 18 patients listed in the two preceding paragraphs, all of the overpayments alleged in those clusters are accepted as such based on the evidence presented, including the Agency's work papers and VMC's admissions, leaving only the question of what to do about the SAOs. All told, VMC admits having received an empirical overpayment of at least $2,488.50. VMC contends, however, that it was underpaid a total of $27.76 in connection with two BGOSs provided to Patient No. 18. VMC asserts that this alleged underpayment offsets the admitted overpayment by an equal amount, so that, in VMC's eyes, the net admitted empirical overpayment (taking into account the SAOs totaling $303.19) is $2,763.93.2/ VMC disputes the Agency's determinations regarding 55 specific BGOSs. Of these, AHCA found in 48 instances that the particular service which VMC had provided was not medically necessary. These 48 determinations relate to ten separate diagnostic procedures. AHCA further found a single instance of incomplete documentation in connection with one of those same ten procedures, bringing to 49 the total number of disputed adjudications pertaining to ten different procedures. Four disputed Agency determinations relate to what are known as "evaluation and management services" ("E/M services") provided (a) in the doctor's office or other outpatient setting to new or established patients or (b) to patients in hospitals. E/M services are billed to Medicaid using codes that reflect the intensity level of service provided. The codes are called "CPT codes"——"CPT" being short for Current Procedural Terminology®, a registered trademark of the American Medical Association, which developed and keeps up-to-date this widely used system for reporting medical procedures and services. Medicaid reimburses providers for E/M services pursuant to fee schedules that specify the amount payable for each level of service according to the CPT codes. It is the provider's responsibility, in presenting a claim to Medicaid for payment, to determine the appropriate CPT code for the service provided. Medicaid generally pays claims upon receipt, without second-guessing the provider's judgment regarding the level of care. When the Agency conducts an investigation to determine possible overpayment to a provider, however, one thing it might review is whether the provider's claims were properly "coded"—— that is, whether the CPT codes on the bills accurately reflected the level of service provided to the patients, as documented in the medical records. If the Agency determines that the level of service provided was lower than that claimed, then it will "downcode" the claim to the proper level and seek to recoup from the provider, as an overpayment, the difference between what Medicaid paid on the claim as originally coded and what it would have paid on the claim as downcoded. In this case, four of the 55 disputed claim determinations involve a downcode. Collectively, these four disputed items total $13.55. In two instances involving Patient No. 18, VMC agrees with AHCA's determination that there was no overpayment for the BGOS in question, but it asserts that Medicaid paid too little on the claims, which could have been billed under higher paying codes. As mentioned above, these alleged underpayments ("UPs") total $27.76.

First, the undersigned has decided that each of the 21 separate SAOs should be treated as no more or less than corroboration that the alleged overpayment is correct——not used as a basis for increasing the amount AHCA alleges is due. Thus, for example, if AHCA alleged that the overpayment for a particular encounter was $36.14 and VMC offered evidence that the overpayment for that encounter was actually $37.64, the undersigned will find that the undisputed overpayment is $36.14. As a result, nothing else needs to be decided in regard to any of the claims presented for BGOSs furnished to Patient Nos. 3, 10, 23, 24, 26, and 32. Second, the undersigned rejects VMC's assertion that the empirical overpayment should be reduced by a total of $27.76 because it provided BGOSs to Patient No. 18 for which it did not bill Medicaid enough.3/ This reduces the number of disputed encounters from 55 to 53. The table below summarizes the disputed overpayments after taking account of the foregoing determinations, sorted by disputed overpayment amount per patient (largest to smallest): Pt. # Disputed OP Admitted OP Alleged OP Number of Disputed BGOSs 22 545.00 401.83 946.83 8 7 523.79 57.75 581.54 5 35 466.10 112.83 578.93 7 6 392.63 75.91 468.54 5 20 253.18 95.77 348.95 6 31 209.73 58.36 268.09 3 27 157.73 479.12 636.85 2 8 157.73 12.85 170.58 2 5 153.54 16.61 170.15 4 18 150.97 280.56 431.53 3 14 110.54 99.77 210.31 1 4 106.29 38.85 145.14 1 33 105.44 182.80 288.24 2 29 51.44 35.01 86.45 1 12 51.09 0 51.09 1 30 47.53 0 47.53 1 1 4.77 0 4.77 1 Subtotal 3,487.50 1,948.02 5,435.52 53 2 0 23.32 23.32 0 3 0 22.08 22.08 0 9 0 23.32 23.32 0 10 0 15.09 15.09 0 11 0 37.58 37.58 0 13 0 32.57 32.57 0 16 0 33.10 33.10 0 23 0 15.09 15.09 0 24 0 18.16 18.16 0 25 0 46.85 46.85 0 Pt. # Disputed OP Admitted OP Alleged OP Number of Disputed BGOSs 26 0 201.04 201.04 0 32 0 36.14 36.14 0 34 0 36.14 36.14 0 Subtotal 0 540.48 540.48 0 15 n/a 0 n/a 17 n/a 0 n/a 19 n/a 0 n/a 21 n/a 0 n/a 28 n/a 0 n/a TOTAL 3,487.50 2,488.50 5,976.00 53 Each side presented opinion testimony regarding the compensability of the disputed BGOSs under Medicaid. On the question of medical necessity, AHCA's medical expert was Ronald Machado, M.D., upon whose testimony, together with the notations of the Agency's nurse reviewer appearing in the audit worksheets, AHCA relies in support of its overpayment allegations. VMC's medical expert was Dr. Michael Sterns, whose written opinions were presented through the report of L. Lamar Blount, a health-care consultant who, at VMC's request, conducted a shadow audit of the claims AHCA had examined. To assist in his review, Mr. Blount engaged the services of a coding specialist (Rae Freeman) and a statistician (Frank Collins) in addition to Dr. Sterns. The undersigned has considered all of the opinion testimony presented, together with the medical records and other evidence received. Each of the findings that follow is based upon a preponderance of the evidence which the undersigned deemed credible and persuasive, and each constitutes a rejection of other evidence to the extent of any conflict between the finding and such evidence. In determining whether a particular claim should be allowed or disallowed, the undersigned considered, as necessary, the relevant provisions of the pertinent statutes, rules, and Medicaid handbooks, the operative terms of which are identified in the Conclusions of Law following these Findings of Fact. The undersigned's determinations as to each of the disputed BGOSs are set forth below in summary fashion, using abbreviations where possible. This is consistent with the manner in which the parties' respective experts addressed the individual claims. The brevity of the discrete rulings is not a reflection of the attention that has been given each item, all of which were carefully and thoroughly examined. For analytical efficiency, the undersigned sorted the disputed claims by procedure, from highest to lowest overpayment subtotal. The claim-specific findings are presented below in that fashion. The descriptions of the procedures are adapted from the American Medical Association's Physician's Current Procedural Terminology® Handbook. Each disputed claim is identified by Patient Number – Encounter Number ("Pt. # - Enc. #"), using the recipient numbers assigned by AHCA. The Encounter Numbers correspond to the identically designated numbers in column C of Appendix D to Respondent's Exhibit JJ, which in turn match the claim numbers appearing in AHCA's "Listing of All Claims in Sample by recip name" worksheet, a 73- page document attached to the FAR, Petitioner's Exhibit 4.

To be clear, each of the numbers in the "ALJ Disallow" column above is based on findings supported by a preponderance of the evidence. The figure of $1,457.15 is not supported, however, by clear and convincing evidence. The grand total of $3,945.65 is, more likely than not, the correct empirical overpayment for the claims in the sample population. The figure of $3,945.65 is not supported, however, by clear and convincing evidence. As mentioned above, AHCA determines the probable total overpayment based upon the empirical overpayment observed in the sample population, using a statistical formula for cluster sampling to extend the empirical data to the provider's entire patient population. AHCA is statutorily authorized to use generally accepted statistical methods in making a determination of overpayment to a provider, and to offer the results of such statistical methods as proof of overpayment.4/ The formula that AHCA uses is reproduced below: VMC contends that the statistical formula upon which AHCA has relied produces less accurate results than other methods that could have been used, and that AHCA made mistakes when it employed the formula in this case. The latter argument is rejected as contrary to the persuasive evidence, which shows that AHCA correctly performed the calculations required to implement the statistical formula for cluster sampling. As for the efficacy of the Agency's formula, the undersigned accepts that there are other statistical methodologies that AHCA could use, and that it would be possible to obtain a more accurate result using other methods. The Agency does not dispute this. But, according to AHCA's expert witness, Dr. Fred Huffer, a statistician whose testimony the undersigned credits with qualifications as explained below, increasing the accuracy of the statistical methodology most likely would result in a higher probable total overpayment because there is supposed to be only a five percent chance that the figure AHCA's formula produces is too high. The undersigned determines that the statistical formula for cluster sampling that AHCA uses is a generally accepted, valid, and reliable method of extending the overpayment observed in a sample population to the entire relevant population. That said, there is less to the relative persuasiveness of the number produced by the Agency's formula than meets the eye. The confidence level of 95 percent assumes that every numerical value going in to the formula is absolutely (not just probably) true. For some of the values, i.e., F, Bi, U, and N, this degree of confidence (namely, 100 percent) is justified. For others, i.e., Ai, it clearly is not. The total overpayment in the sample cluster is not an objective truth, such as the number of clusters in the random sample, or a mathematical constant such as pi. Rather, each alleged overpaid claim in the sample reflects a judgment by AHCA (or more precisely its medical reviewers) founded on findings of historical fact, legal conclusions, and determinations of ultimate fact. Indeed, each figure contributing to the total empirical overpayment numerically represents an ultimate factual determination based upon the application (and interpretation when necessary) of Medicaid rules to a limited body of evidence——mostly medical records——of past events. Of none (or very few) of those figures can it be said with 100 percent certainty that the number is absolutely (not just probably) true. No one involved in the decision making process is omniscient or infallible. As here, the provider may dispute some or all of AHCA's preliminary adjudications of the claims behind the total alleged overpayment in the sample cluster and demand a hearing, at which each (disputed) individual overpayment in the sample cluster must be proved by a preponderance of the evidence. The standard of proof being what it is, the Agency does not need to prove each of the disputed overpayments to an absolute certainty. To recoup an overpayment, it is sufficient for AHCA to show with a 51 percent probability that the amount alleged to have been overpaid for a given claim is, in fact, the amount overpaid. In the paragraphs above, the undersigned has set forth his findings regarding the disputed claims. Each individual finding of an overpayment reflects the undersigned's determination that the disallowed amount is, more likely than not, the correct adjudication of the disputed claim. There is, in the undersigned's estimation, approximately a 60 percent probability that the sum of all adjudicated overpayments ($1,457.15) is the correct figure, which satisfies the preponderance of evidence standard. In contrast, the undersigned estimates that there is approximately an 80 percent probability that the sum of all admitted overpayments ($2,488.50) is the correct figure, meaning that this portion of the empirical overpayment was established by clear and convincing evidence. This discussion of the undersigned's relative confidence in the overpayment findings made in this Recommended Order is meant to demonstrate that using the figure $3,945.65 as the value Ai in the Agency's formula for cluster sampling, while consistent with the standard of proof for an action to recoup an overpayment, nevertheless injects uncertainty into the equation, which logically must reduce the confidence level in the formula's outcome from 95 percent to something less than that.5/ Based on the instant record, the undersigned cannot quantify the probable accuracy of the formula's output, as applied to the facts found here. The bottom line is that although the undersigned finds AHCA's statistical formula to be a sufficiently reliable method of calculating, to the degree of certainty required under the preponderance of evidence standard of proof, the total probable overpayment to VMC, the formula's output (in this instance) does not satisfy the stricter clear and convincing standard.6/
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that AHCA: Recalculate the probable total overpayment using the statistical formula for cluster sampling to extend the empirical overpayment of $3,945.65 in the sample population to the entire population during the Audit Period. Make a preliminary determination of the amount of costs that may be recovered from VMC, taking into consideration the financial resources, earning ability, and needs of VMC to the extent VMC demonstrates such factors. Remand the matter to DOAH for an evidentiary hearing on recovery of costs if necessary. Enter a final order directing VMC to repay the Agency the total probable overpayment as recalculated using the findings herein, plus statutory interest, for paid claims covering the period from January 1, 2010, to December 31, 2012; imposing an administrative fine against VMC in the amount of $5,000; and taxing recoverable costs, full payment of these monies to be due within 30 days after the rendition of the final order and payable on the Agency's instructions.

The Issue Whether the Petitioner should reimburse the Respondent for alleged Medicaid overpayments in the amount of $44,581.50.
Findings Of Fact At all times material to the allegations of this case, the Petitioner, Roosevelt T. Jackson, Jr., M.D., has been a Medicaid provider authorized to receive reimbursement for Medicaid services provided to Medicaid recipients. Dr. Jackson is an ophthalmologist. All services in this cause related to Medicaid claims for procedures performed between January 1, 1998, and December 31, 1999. The Respondent is the state agency responsible for the administration of the Medicaid program within the State of Florida. Medicaid Program Integrity is the arm of the Agency that oversees the activity of the Florida Medicaid providers and recipients to ensure that they are in compliance with the Medicaid program. As part of its duties, the Agency audits the records of providers to verify compliance with all Medicaid rules. In this case the audit of Petitioner's records was triggered by a computer program that reviews data from similar Medicaid providers. The Surveillance Utilization Review Section (SURS) of the Medicaid Program Integrity office found that the Petitioner had exceeded the norm in Medicaid billings when compared to his peers. When the SURS kicked back the Petitioner's name, it represented that the Petitioner had exceeded his peers in the total number of Medicaid recipients serviced, total number of evaluation and management procedures, average number of evaluation and management procedures per recipient, number of office visits, average number of office visits per recipient, and average number of services per recipient. Based upon the SURS responses, the Agency elected to conduct a sample audit of the Petitioner's records. Records for 30 Medicaid recipients were requested and obtained from the Petitioner. The results of that sample audit were then extended to calculate the overpayment for which the Respondent currently seeks reimbursement. The Respondent's audit established that the Petitioner had failed to comply with Medicaid provisions in three specific areas. First, based upon the records submitted to the Agency, the Petitioner billed for services at a higher level than actually performed. Second, the audit established that the Petitioner billed for services that were "medically unnecessary" as that term is utilized by Medicaid. And third, the audit found that the Petitioner billed for services that were not properly documented by the records maintained. Such records were created, maintained and produced to the Agency by the Petitioner. The results of the audit were set forth in the Final Agency Audit Report and were provided to the Petitioner. The report requested reimbursement from the Petitioner in the amount of $44,581.50. The report was completed on or about June 27, 2001. Thereafter, the Petitioner timely challenged the results of the audit, and requested a formal administrative hearing to dispute the amounts set forth in the report. As to all amounts claimed in the report, the evidence presented in this cause supports the Agency's conclusions as to the overpayment. Prior to January of 1999, the Petitioner was not authorized to bill for a level 4 visit. Thus all services billed at that rate prior to January 1999 should be reduced. Secondly, none of the records supplied by the Petitioner supported the complexity required for a level 4 billing. Therefore, services billed at the level 4 rate should be reduced to the appropriate level. The Petitioner also billed for services that were not medically necessary. A normal examination (with no retinal problem identified in the record) would not warrant additional retinal examinations. Therefore, billings for additional procedures would not be warranted in such cases. Finally, Medicaid rules require that a physician maintain records in compliance with documentation guidelines. The Petitioner's records did not comply with such guidelines. Accordingly, Medicaid payments for services that lack the required documentation may be recouped. After a full review of the records submitted, the Agency used a standard formula to extend the sample data throughout the population from which the sample was taken. That is, from the 30 patient records reviewed, the results were applied by statistical formula to the entire Medicaid patient population served by the Petitioner. This computation resulted in the amount of the overpayment currently sought. The statistical formula used by the Agency to compute the overpayment was reasonable and within the guidelines of the law.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Agency for Health Care Administration enter a Final Order confirming the Medicaid overpayment in the amount of $44,581.50.

The Issue Whether the Petitioner, Cesare Raoli, M.D., must reimburse the Respondent, Agency for Health Care Administration, for an alleged overpayment of Medicaid funds for the audit period February 22, 1997 through February 22, 1999.
Findings Of Fact At all times material to the allegations of this case, the Respondent is the state agency charged with the responsibility of administering the Florida Medicaid Program. At all times material to the allegations of this matter the Petitioner was a Medicaid provider. It is undisputed the Petitioner received payments for services rendered to Medicaid recipients during the period of time covered by the audit at issue in this proceeding. The audit period for purposes of this case was February 22, 1997 through February 22, 1999. As a Medicaid provider the Petitioner is required to comply with a Medicaid Provider Agreement. Additionally, all services provided by the Petitioner must be fully and completely documented by records maintained by the provider. Such records must comply with the Physicians Coverage and Limitations Handbook, and the Florida Medicaid Provider Reimbursement Handbook. In performing an audit such as the one at issue, the Respondent reviews the provider's records to verify that the appropriate documentation supports the amount paid to the provider for the service rendered. In this case the parties have not challenged the authenticity of the patient records. The parties stipulated to the use of all patient records addressed in this order. In this case, the Respondent claims the psychiatric codes billed by the Petitioner (and paid by the Agency) are not supported by the documentation submitted by the Petitioner. In many instances the billing code was "down graded" to a lesser amount. As a result the difference between that paid and the amount documented is the amount of the overpayment sought. In other instances the documentation did not support any charge and the entire amount is claimed for reimbursement. When a provider signs on to the Medicaid program the Respondent provides copies of the handbooks identified in paragraph 3. Additionally, although supplied at the time of enrollment in the program, the handbooks are also available thereafter. When an audit is performed of a provider's records, the handbooks, billing codes, and types of services applicable for the type of provider are reviewed. In this case the Petitioner is a psychiatrist. The Agency reviewed Petitioner's records to determine if the service provided was medically necessary and properly documented. For billing purposes when psychiatric codes 90805, 90806, 90807, 90808, 90809, 90812, 90813, 90815, or G0078 were used, the Petitioner was required to document the specific time spent providing the service to the recipient. In many instances the Petitioner's records did not include a specific time. The Petitioner conceded that he did not note the length of the time spent with the patient and that the specific time is required by the billing guidelines. Similarly, when the records were reviewed at hearing, the Respondent conceded (and therefore eliminated) some of the disputed charges paid to the Petitioner. Consequently, the reimbursement amount now claimed by the Respondent is less than the amount previously sought. In performing an audit such as the one at issue, the Respondent took a random sample of all claims filed by the Petitioner for the audit period. After the computer program generated and identified 41 claims randomly selected, the individual records were fully reviewed. The use of a random sample of 41 (from 376) is statistically valid for purposes of extrapolating the results of the sample and applying it to the whole claims for the period of the audit. In fact, within a statistical certainty, the amount claimed in this cause based on the 41 records used is lower than the reimbursement amount actually owed by the Petitioner if all records were reviewed. The Respondent established that its methodology in computing the overpayment was statistically valid. The Petitioner did not document or refute with any statistical or actual analysis that the methodology could not be accepted. Moreover, the Petitioner did not produce records to support an argument that the extrapolation is factually unreliable. To fully review the 41 claims, the patient records associated with the claims were introduced at hearing. On a claim-by-claim basis each individual document was reviewed to determine if it was accurately billed to Medicaid. Listed by recipient number the claims totaled 218 entries. The Respondent has acknowledged that there is no overpayment claimed for recipient numbers 5, 17, 20, 22, 30, and 34. As to recipient number 1, the Petitioner withdrew his challenge to the overpayment as to all claims submitted for April 7, 1998. As to recipient number 2, the Petitioner withdrew his challenge to the overpayment as to the claim dated August 12, 1997. As to recipient number 3, the Petitioner did not either submit documentation to support the claims or specify the time spent with the patient. Accordingly, the Respondent has established the overpayment for this recipient. As to recipient number 4, the Petitioner did not specify the time spent with the patient. Accordingly, the Respondent has established the overpayment for this recipient. As to recipient number 6, the Petitioner did not either submit documentation to support the claims or specify the time spent with the patient. Accordingly, the Respondent has established the overpayment for this recipient. As to recipient number 7, the Petitioner withdrew his challenge to the claim overpayment for December 6, 1997. The Respondent withdrew its overpayment claim for two of the codes for May 4, 1998, however the third claim for that date had no documentation and should be reimbursed. As to recipient number 8, the Petitioner conceded the overpayment amount. As to recipient number 9, there was no documentation to support the claim billed therefore the overpayment is established. As to recipient number 10, the Petitioner either withdrew his challenge to the overpayment or presented no documentation to support the claim as billed. Therefore, the overpayment is established as to this recipient. As to recipient number 11, the Respondent conceded the claim for June 30, 1998, therefore this overpayment must be eliminated. As to the other two dates of services, the Petitioner did not provide a specific time in the record. Accordingly the overpayment has been established for December 18, 1998 and January 25, 1999. As to recipient number 12, either the Petitioner failed to document a specific time in the record, did not document the examination claimed, or withdrew his challenge to the overpayment. Therefore, the overpayment as to this recipient has been established. As to recipient number 13, the Petitioner failed to document the service. Therefore, the overpayment as to this recipient has been established. As to recipient number 14, the Petitioner failed to document the specific time spent with the recipient. Therefore, the overpayment as to this recipient has been established. As to recipients numbered 15, 16, 18, 19, 21, 23, 24, 28, 29, 32, 33, 36, 37, 38, 39, and 41, either the Petitioner withdrew his challenge to the amount of overpayment claimed, supplied no documentation to support the claim, or the Respondent conceded the original claim amount. Accordingly, while not in the amount originally claimed by the Agency, an overpayment for these recipients has been established. As to recipient number 25, the Respondent has conceded the claims dated July 8 and July 10, 1998. As to the other claims for this recipient, the Petitioner either provided no documentation to support the amount of the claim or failed to document the specific time spent with the recipient. Therefore, the Respondent has established an overpayment as to this recipient. As to recipient number 27, the Petitioner has conceded the correct billing code for the date of service April 19, 1998, should have been 99215, thereby supporting the overpayment claim. The Respondent conceded the code billing for the second service of that date. As to recipient number 31, either the Respondent conceded the billed amount, or the Petitioner agreed to a reduced code billing, or no time was specified, or the Petitioner withdrew his challenge to the overpayment. Therefore, although not in the amount of its original overpayment claim, the Agency has established an overpayment as to this recipient. As to recipient numbers 35 and 40, either the Petitioner withdrew his challenge to the overpayment claim, did not perform the service billed, or provided no documentation to support the service billed. Therefore, the overpayment as to this recipient has been established. As to every instance where the specific time spent with the recipient was not documented, the medical records provided by the Petitioner were the sole source of information available to the Respondent. No medical expertise is necessary to determine whether or not the specific time was posted on the records. Similarly, where no document was provided to support a claim, medical expertise is not required to disallow such claim. It is undisputed that the Petitioner served Medicaid- eligible recipients. Additionally, there is no claim that the recipients served (and whose records were reviewed) were not eligible for the service provided. The Petitioner did not willfully or fraudulently overstate the claims. In order to perform a "peer review of records," the Respondent's agent does not have to directly interview the recipient regarding the services rendered.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that the Agency for Health Care Administration enter a Final Order requiring the Petitioner to reimburse the state for an overpayment of Medicaid funds. Such overpayment must be calculated using the revised amounts for each of the recipients identified in this record and extrapolating the total to claims for the entire audit period.
