MELLOY, Circuit Judge.

       Key Medical Supply, Inc. ("Key Medical"), a medical equipment provider in
the Minneapolis-St. Paul area, alleges that the Department of Health and Human
Services' Centers for Medicare and Medicaid Services ("CMS" or "the Agency")
exceeded its statutory authority when implementing a competitive-bidding system for
Medicare's pricing of medical equipment and supplies. Key Medical acknowledges
that the governing statute contains a strongly worded ban on administrative and
judicial review. Key Medical argues, however, that review should be available
because the Agency acted in an ultra vires manner by: (1) imposing arbitrary and
non-competitively-derived maximum bid caps for certain products; (2) grouping
inexpensive commodity products with more expensive custom-fit products for
bidding purposes; and (3) applying the competitive bidding program in a manner that
interferes with the separate state/federal Medicaid system. Key Medical also argues
that review should be available for constitutional claims asserting that the Agency's
actions deprived Key Medical of due process and effected an unconstitutional taking
of Key Medical's "business." The district court3 rejected Key Medical's arguments
and determined that the statutory bar on review precluded jurisdiction. We affirm.

I.    Background

      A.     General Background: 42 U.S.C. § 1395w-3 Medicare Competitive
             Bidding System for Certain Items and Services

       In 2003, Congress amended Medicare to control costs for durable medical
equipment, prosthetics, orthotics, and supplies, based in part on a conclusion that
Medicare and beneficiaries were overpaying substantially for such items. H.R. Rep.
No. 108-178, pt. II, at 144 (2003) ("The Office of Inspector General has documented
that taxpayers and Medicare beneficiaries are paying millions more for durable
medical equipment than other programs, such as the Federal Employees Health
Benefit Program (FEHBP)."). The amendments required the Agency to phase in a
competitive bidding system to replace an existing government-defined price schedule.
Medicare Prescription Drug, Improvement, and Modernization Act, Pub. L. No. 108-
173, title III, § 302(b)(1) (2003) (codified in part at 42 U.S.C. § 1395w-3). This
change followed successful pilot studies in two cities and began with a first round of
competitive bidding in ten large metropolitan areas. Balanced Budget Act of 1997,
Pub. L. No. 105-33, § 4319 (authorizing pilot studies); 42 U.S.C. § 1395w-
3(a)(1)(B)(i)(I) (requiring a limited area, first-round program in 2007). Congress then
received feedback, issued further amendments, and provided by statute that the first
round contracts were to be re-bid in a second round. Medicare Improvements for
Patients and Providers Act of 2008, Pub. L. No. 110-275; see generally Texas
Alliance for Home Care Servs. v. Sebelius, 

, 405–06 (D.C. Cir. 2012)
(discussing the genesis and evolution of the durable medical equipment competitive
pricing program). Later, the second round took place and included many additional
geographic bidding areas. The Minneapolis-St. Paul area is a second-round bidding
area.

      Because Key Medical primarily advances an ultra vires argument, it is
important to note the plain text and overall structure of the amendments which show


                                         -3-
the extent and nature of authority granted to the agency. Congress tasked the Agency
with a broad and general mandate to "establish and implement programs under which
competitive acquisition areas are established throughout the United States for . . . the
furnishing under this part of competitively priced items and services." 42 U.S.C.
§ 1395w-3(a)(1)(A). In doing so, Congress granted relatively unconstrained authority
to the Agency as to many issues, while narrowly defining and limiting authority as
to other issues. This is evident in the statute's use of the terms "may" to identify
factors for the Agency's discretionary consideration; "shall" to identify mandatory
tasks; and "may not" or "shall not" to identify prohibited actions.

       For example, 42 U.S.C. § 1395w-3 sub-parts (b)(4)(A) and (b)(4)(B), read
together, show that the Secretary "may" limit the number of contractors awarded
contracts for a bidding area, but "shall" grant contracts to multiple entities (i.e., the
number of contractors may be reduced, but must be kept greater than one). Also,
Congress gave the Agency discretion to choose products for inclusion in the
competitive bidding system and expressly authorized—but did not require—the
Agency to evaluate the relative medical efficacy of different items for inclusion,
exclusion, or grouping purposes. See 42 U.S.C. § 1395w-3(b)(7) ("The Secretary
may consider the clinical efficiency and value of specific items within codes,
including whether some items have a greater therapeutic advantage to individuals.")
(emphases added). Similarly, Congress granted the Agency the authority ("may
establish") but not the obligation to specify certain items for exemption from
competitive bidding and also to leave the use and "mode of delivery" of such items
to physician discretion. See 

As these last two citations
illustrate, Congress empowered the Agency to exercise its judgment and discretion
in choosing the items that would be subjected to competitive bidding (and what items,
due to perceived medical necessity, would not). Further, Congress prohibited
payments to vendors who had not submitted bids for items and services and who had
not been awarded contracts by the Agency. 

("payment shall
not be made . . .").

                                          -4-
       Several sub-parts of the statute illustrate that Congress made timely
implementation a priority. For example, Congress gave the Secretary discretion to
waive more generally applicable acquisition regulations and provided that
implementation was to move forward even if various quality-standard regulations
were not complete. 42 U.S.C. § 1395w-3(a)(1)(C). Importantly for the present case,
Congress also provided that seven broad types or categories of administrative actions
in the process of creating and implementing these changes would be immune from
judicial and administrative review:

      (b)(11)       There shall be no administrative or judicial review under
                    section 1395ff of this title, section 1395oo of this title, or
                    otherwise, of–

             (A)    the establishment of payment amounts under paragraph (5);
             (B)    the awarding of contracts under this section;
             (C)    the designation of competitive acquisition areas under
                    subsection (a)(1)(A) of this section and the identification
                    of areas under subsection (a)(1)(D)(iii) of this section;
             (D)    the phased-in implementation . . . of this section...;
             (E)    the selection of items and services for competitive
                    acquisition under subsection (a)(2) of this section;
             (F)    the bidding structure and number of contractors selected
                    under this section; or
             (G)    the implementation of the special rule [concerning diabetic
                    supplies].

42 U.S.C. § 1395w-3 (emphasis added). It is noteworthy that this ban on review is
broad. Sub-part (b)(11) states that there "shall be no administrative or judicial review
. . . or otherwise." And, the seven enumerated areas listed in the ban are categorical;
the statute does not carve out reviewable and non-reviewable aspects of these seven
categories. Sub-parts (b)(11)(A), (B), (E), and (F) are material to the present
case—review is expressly barred as to "the establishment of payment amounts," "the



                                          -5-
awarding of contracts," "the selection of items . . . for competitive acquisition," and
"the bidding structure[.]"

      B.     Implementation of the Competitive Bidding System and Its Impact on
             Key Medical

       Because the district court dismissed this case pursuant to Federal Rule of Civil
Procedure 12(b)(1), we present the facts as asserted in Key Medical's complaint and
in the light most favorable to Key Medical. See Great Rivers Habitat Alliance v.
F.E.M.A., 

, 988 (8th Cir. 2010). Enteral nutrition supplies, including
low-profile, custom-fit feeding tubes are an important product for Key Medical's
business.4 Key Medical provided such feeding tubes to many customers, including
some customers with developmental disabilities who were "dually eligible" for
assistance from Medicare and also from Minnesota's Medicaid system. Key Medical
explains that the interplay between these two medical payment programs requires that
providers be eligible to receive payment from Medicare before they are allowed to


      4
        In its initial complaint, Key Medical provides a helpful description of regular
and low-profile feeding tubes. Both types of tubes are for use with patients who have
a stoma (an opening or portal) in their abdominal and stomach walls. The regular
tubes are a much less expensive commodity that may extend for many inches outside
the stoma. The low-profile tubes similarly enter through a stoma, but are custom
fitted to end at skin level with a sealable port. Key Medical describes such ports as
being roughly similar to the extendable inflation valves on beach balls. Key Medical
argues low-profile tubes are medically superior if not necessary for some patients
(e.g. infants, mentally diminished persons, persons subject to seizures or thrashing)
because such patients cannot be stopped from pulling out normal tubes. Neither party
discusses the means through which regular tubes might be secured to allow use with
such special-needs patients, but it appears undisputed that regular tubes are not ideal
for such patients. It also appears undisputed that special needs patients can,
ultimately, receive nutrition with regular tubes, albeit with complications, additional
labor, additional risks, inconvenience for the patients and caregivers, and added
discomfort for the patients.

                                          -6-
receive payment from Medicaid. For dually eligible patients, Medicaid is the payor
of last resort and reimbursement requests must first be submitted to and denied by
Medicare before Medicaid will reimburse providers.

       Key Medical described differences and relationships between these two
programs and explained how its own business coordinated with these programs prior
to implementation of competitive bidding. First, Medicare would reimburse
providers for low-profile tubes at a scheduled rate of approximately $40 per tube and
would allow replacement of a patient's tube once every 3 months. Medicaid, on the
other hand would reimburse providers at a rate from $140–$530 per tube (depending
on the particular tube) and allow replacements up to twice per month. For dually
eligible patients, Key Medical would provide a first tube, billed to Medicare for
approximately $40 (at a substantial loss—Key Medical alleges the wholesale
acquisition cost of such tubes ranges from $100 to $330). Key Medical would then
sell additional tubes, Medicare would deny payment, and Medicaid, as the payor of
last resort, would reimburse Key Medical at the higher and profitable price of
$140–$530. Under this dual system, which Key Medical described as "far from
perfect" and "convoluted," the Medicare-provided tubes were essentially loss leaders
that Key Medical sold to be eligible to provide tubes later, at a profit, through the
state Medicaid system.

     Key Medical's primary grievance in this matter and the primary source of Key
Medical's asserted financial harm stems from its de facto exclusion from Minnesota's
Medicaid system. To understand this potential consequence of the Medicare
competitive bidding system, we now turn to the competitive bidding system and its
implementation process.

       Key Medical explains that the Medicare competitive bidding process required
entities to submit information demonstrating their financial health, explaining the
quantity of product they could provide, and identifying a bid price at which the entity

                                         -7-
could provide products. See 42 C.F.R. § 414.414(b). The Agency would then
determine the quantity of product it anticipated would be needed in a geographic
bidding area and set a single reimbursement price for all providers in that area. 

The single reimbursement price was based on the bid price at which
the necessary quantity could be provided by the several providers whose bids were
at or below that bid price. 

providers who submitted bids were
eligible to receive contracts, and providers could only receive a contract for a
category of goods if they submitted bids for the items in that category. 42 U.S.C.
§ 1395w-3(b)(6)(A).

      Key Medical's arguments in this case focus on the fact that the Agency did not
allow providers free reign in constructing their own bids. Rather, in implementing
the competitive bidding system, the Agency borrowed the pre-existing government-
schedule prices as maximum bids that it would accept from bidders. In addition, the
Agency required that parties' bids be sufficient to cover the providers' acquisition
(wholesale) cost for the item plus some amounts for overhead and a reasonable profit.
The parties refer to these requirements as the requirement that bids be "bona fide
bids." The statute does not employ the term "bona fide bids." Agency regulations
employ the term with reference to the requirements of applicable requests for bids.
See 42 C.F.R. § 414.414(b)(4).

       According to Key Medical, the pre-existing government-scheduled price for
general feeding tubes is below Key Medical's acquisition cost for custom-fit, low-
profile feeding tubes. Also according to Key Medical, the Agency established a
website for vendors to use when submitting bids, but the site would not allow users
to differentiate between types of feeding tubes or allow feedback to address such
issues. Key Medical alleges this system prevented Key Medical from submitting a
bona fide bid because Key Medical's acquisition cost for custom-fitted, low-profile
tubes (more than $100 per tube) exceeded by far the permissible bid cap for general



                                         -8-
feeding tubes (approximately $40), even without adding amounts for profit and
overhead.

       Key Medical also describes how the failure to submit a bona fide bid for an
item or category carries severe consequences. Namely, the failure to submit a bid for
a category of products (or the submission of a bid too low to cover the bidder's
acquisition costs, some profits, and some overhead) results in that vendor's exclusion
from receiving a contract for the entire associated category of products. Key Medical
also asserts that, due to the interplay between the Medicare and Medicaid systems,
Key Medical cannot serve as a Minnesota Medicaid provider unless it is eligible for
payment from Medicare. In this regard, it appears uncontested that the Minnesota
Medicaid system only allows payments to vendors who are also eligible for Medicare
reimbursement because claims must be submitted first to Medicare and only
secondarily to Medicaid (with Medicaid being the payor of last resort). According
to Key Medical, this de facto exclusion from the Minnesota Medicaid regime for
providing custom-fitted, low-profile feeding tubes causes Key Medical substantial
profit loss and removes at least some choice of equipment provider from Key
Medical's clients and former clients.

      Implementation of the competitive bidding system resulted in a single
competitive-bid price for feeding tubes in the Minneapolis-St. Paul area of less than
$40 and resulted in an award of contracts to 8 providers who listed local addresses
and 14 mail-order or out-of-area providers to supply such tubes for Medicare (22
providers or vendors overall). Notwithstanding the awarding of contracts to 8 local
bidders and 22 bidders overall, Key Medical argues that implementation has
impermissibly reduced patient choice of provider. Key Medical also argues that many
high-need patients may not have adequate access to low-profile feeding tubes.




                                         -9-
      C.     Procedural History

       Key Medical brought the present action in the District of Minnesota, asserting
a claim under the Administrative Procedures Act (APA) and also asserting
constitutional violations. The APA claim alleged arbitrary and capricious agency
action related to the use of the old price-schedule amounts as bid caps, the grouping
together of regular and low-profile feeding tubes, and the bona fide bid requirement
and its impact on vendors' ability to continuing participating in the separate Medicaid
system. As relief, Key Medical sought to enjoin the Agency from: (1) implementing
competitive bidding for "all Enteral Nutrients, Equipment, and Supplies," (2) utilizing
a web-based bidding system "which rejects submissions of the actual and truthful
acquisition costs," and (3) including in the competitive bidding program the provision
of supplies to dually eligible patients.

       The district court expressed substantial concern at the impact the Agency's
competitive bidding regime would have upon dually eligible patients with
developmental disabilities who use custom-fitted low-profile feeding tubes. The
court, however, applied the bar on review and dismissed the APA claim for lack of
jurisdiction. The court also held the constitutional claims were substantively
insufficient to create jurisdiction under a constitutional-question exception to the
statutory bar on review. Key Medical appeals.

II.   DISCUSSION

      A.     General Applicability of the Bar on Review

       We review a Rule 12(b)(1) dismissal de novo. Longaker v. Bos. Scientific
Corp., 

, 661 (8th Cir. 2013). In the absence of a viable ultra vires
argument or constitutional claim, the § 1395w-3(b)(11) statutory bar applies to the



                                         -10-
present facts.5 The bar is clear on its face and broad in its listing of protected actions.
See Texas Alliance for Home Care 

("The presumption of
reviewability here is overcome by the specific and emphatic statutory language
prohibiting judicial review of the competitive bidding procedure."); see also 

combined with the broad range of subjects expressly immunized from
review, manifest the Congress's intent to proceed with these initial administrative
processes without risk of litigation blocking the execution of the program.") (internal
quotation marks and citation omitted). As already noted, the several sub-parts of the
bar define types of actions or decisions that are shielded from review, and the
challenged actions fall within several of these categories: "(A) the establishment of
payment amounts," "(B) the awarding of contracts," "(E) the selection of items and
services for competitive acquisition," and "(F) the bidding structure and number of
contractors selected[.]" 42 U.S.C. § 1395w-3(b)(11). Like the D.C. Circuit, we find
no basis in the statute or otherwise to adopt a narrow construction of the facially
broad and emphatic bar. See Amgen, Inc. v. Smith, 

, 113 (D.C. Cir.
2004) ("If a no-review provision shields particular types of administrative action, a
court may not inquire whether a challenged agency decision is arbitrary, capricious,
or procedurally defective, but it must determine whether the challenged agency action
is of the sort shielded from review.").

       B.     Ultra Vires Agency Action

     Turning, then, to the possibility of review under an ultra vires theory, we reject
Key Medical's characterization of the agency actions at issue as ultra vires. Although


      5
       The only opinion to construe the bar on review narrowly (and therefore in a
manner potentially helpful to Key Medical) is a district court order from California
that was subsequently vacated at the parties' request pursuant to a settlement
agreement. See Sharp Healthcare v. Leavitt, 

(S.D. Cal. 2008),
vacated by Order Granting Joint Motion to Vacate Court's Interlocutory Orders, Case
No. 08–Civ.–170, Doc. Entry 53 (S.D. Cal. July 22, 2010).
                                           -11-
an ultra vires action may be reviewed even in the face of statutory bar on review, our
court has expressed a clear disinclination to accept plaintiffs' characterization of
agency actions as ultra vires where is it possible to characterize a dispute merely as
one of statutory interpretation concerning the scope of agency authority. See, e.g,,
Neb. State Legis. Bd., United Transp. Union v. Slater, 

, 659–60 (8th Cir.
2001). Rather, in order for an agency action to be ultra vires, there must be a "plain
violation of an unambiguous and mandatory provision of the statute." 

(citation and internal quotation marks omitted). There is no such plain violation here.



     In Nebraska State Legislative Board, our court rejected an ultra vires type
argument in the face of a jurisdictional statute-of-limitations bar, stating:

      As a general rule, courts "have interpreted [the ultra vires exception] as
      sanctioning [review] in a very narrow situation in which there is a 'plain'
      violation of an unambiguous and mandatory provision of the statute."
      American Airlines, Inc. v. Herman, 

, 293 (5th Cir. 1999).
      Thus . . . "review of an 'agency action allegedly in excess of authority
      must not simply involve a dispute over statutory interpretation.'" 

Corp. v. Pena, 

, 269 (5th Cir. 1997)). Nor
      will a mere allegation of ultra vires action suffice. West v. Bergland,
      

, 717, 720 (8th Cir. 1979) ("Bergland"), cert. denied, 

(1980). In Bergland, although an appellant had characterized
      his challenge to a regulation as an ultra vires one, we disagreed, holding
      it was merely one of statutory construction. 

Such is also the
      case here. FRA's decision to exempt certain employees from
      certification "is by no means a clear departure from [the] statutory
      mandate or an abridgment of [UTU's] statutory right." 

      (internal quotations omitted).

–60; see also Am. Soc'y of Cataract and Refractive Surgery v. Thompson,

, 456 (7th Cir. 2002) (rejecting an ultra vires argument in the context of
a different Medicare provision and stating, "petitioners argue . . . the Secretary


                                         -12-
violated a clear statutory mandate and exceeded the scope of her delegated authority
[but] we . . . . find the . . . regulation to be a reasonable interpretation of an unclear
statutory mandate . . . .") (internal citations omitted).

       While Nebraska State Legislative Board involved a slightly different context
than the present case, its discussion of what it means for an action to be ultra
vires still applies. There, rather than a bar on judicial or administrative review, the
issue was whether a request for review under the Hobbs Act could be entertained
even though the request for review was filed after a 60-day jurisdictional limitations
period had 

. Even though the context was different, the
impact was the same: a broad and general bar on jurisdiction cannot be avoided by
characterizing mere fights over statutory interpretation as ultra vires claims.

       In contrast, an example of a clearly ultra vires action and the violation of an
unambiguous statutory mandate can be found in Leedom v. Kyne, 

(1958). There, the Supreme Court held that the National Labor Relations Board had
taken an ultra vires action when, without the consent of professional workers, it
approved a collective bargaining unit that included both professional and non-
professional 

–89. The action was deemed ultra vires
because the authorizing statute, section 9(b)(1) of the National Labor Relations Act,
expressly prohibited the inclusion of professional employees within such units
without the consent of the professional employees. 

action in
that case—agency action in direct contravention of an express and narrowly defined
limit on agency authority—was deemed ultra vires. 

have suggested a greater willingness to accept arguments
characterizing agency action as ultra vires where the potentially applicable statutory
bar is ambiguous or narrow. For example, the D.C. Circuit noted that review under
a theory of ultra vires agency action "is favored . . . 'if the wording of a preclusion
clause is less than absolute.'" 

(quoting Dart v. United States,

                                          -13-


, 221 (D.C. Cir. 1988)). The court concluded, however, that the
language at issue in Amgen—language almost identical to the bar on the present
case— was clear and barred review. 

articulated as a multi-factored test, these cases collectively
illustrate the need to examine (1) the clarity and specificity of the bar on review; (2)
the breadth of the Agency's statutory authorization; (3) the scope of any express
statutory limits on the Agency's authority; and (4) the relationship between the action
taken and these other three factors. In the present case, the bar on review is not only
broad but lists in detail several aspects of the competitive bidding system using
categorical language ("awarding of contracts," "selection of items," "the bidding
structure") rather than targeting only small or specific aspects of the system. In
addition, the statutory authority for the Agency's action is broad and relatively
unconstrained: Congress made timely implementation a priority and gave the agency
broad license to build a competitive-bidding system free of most judicial oversight.
And, importantly, the actual detailed and specific actions that Key Medical complains
about (the lumping together of regular and low-profile feedings tubes and the use of
maximum bid caps), are within broad statutory authority and not contrary to any
specific limits on authority.

       Key Medical attempts to identify clear violations of statutory authority, but we
conclude that, in each instance, Key Medical has identified mere issues of statutory
interpretation. For example, 42 U.S.C. § 1395w-3(b)(2)(A)(iii) requires that
competitive bidding for a category of products in a given bidding area only be
adopted if overall cost savings are realized for the category. Key Medical argues that
adoption of the pre-existing, government-defined scheduled price as the maximum
bid cap effectively imposes a requirement of item-by-item cost savings rather than
category-based cost savings. While this may be true, it does not make the Agency's
action ultra vires. This argument presents only a question of statutory interpretation
because Congress did not instruct the Agency as to how to ensure or achieve

                                         -14-
category-wide cost savings. And, the use of pre-existing scheduled prices as
maximum bid caps is not "a clear departure from [the] statutory mandate," 

(internal quotation marks omitted), of ensuring category-wide cost
savings.

       Still focusing on the maximum bid cap, Key Medical argues that such caps are
inherently non-competitive, are not bid-based, and, as such, are in conflict with a
statutory mandate to establish a system of competitive pricing under which payments
"shall be based on bids submitted and accepted . . . ." 42 U.S.C. § 1395w-3(b)(5)(A).
Again, we conclude this argument presents a mere question of statutory interpretation
rather than a clear and unambiguous statutory violation. Congress did not instruct the
Agency as to how to design a competitive bidding system, and Congress did not
expressly preclude the use of non-competitively derived elements within such a
system. Simply put, Congress instructed to the Agency to design a system under
which payments would be "based on bids submitted and accepted," but Congress did
not exclude the consideration or reliance on other, additional factors when
establishing payment amounts.

       Also, it is a matter of statutory interpretation whether the term "bid" must be
viewed as inherently limited to unconstrained bids by market participants or whether
the Agency may impose limitations on permissible bids. Congress defined the term
bid to mean "an offer to furnish an item or services for a particular price and time
period that includes, where appropriate, any services that are attendant to the
furnishing of the item or service." 42 U.S.C. § 1395w-3(b)(6)(B). This definition
does not necessarily preclude the Agency from imposing a price ceiling or from
imposing requirements as reflected in the Agency's requirement for "bona fide bids."
Because this issue, like all ultra vires arguments Key Medical raises in this case,
presents a matter of statutory interpretation rather than a clear statutory violation, we
must reject Key Medical's attempt to avoid the bar on review under an ultra vires

(finding no "'plain' violation of an
unambiguous and mandatory provision of the statute") (citation omitted).6

       Finally, Key Medical argues that implementation of the competitive bidding
regime impermissibly infringes on patients' protected choice of provider. This
argument is without merit as the statute implicitly anticipates a reduction in patient
choice by expressly granting the Agency authority to "limit the number of contractors
in a competitive acquisition area, 42 U.S.C. § 1395w-3(b)(4)(A), while requiring only
that the Agency "award contracts to multiple entities," 

    Constitutional-Claim Exception

       Regarding the constitutional claims, Key Medical argues that implementation
of the competitive bidding regime amounted to an unconstitutional taking of its
business. Key Medical also argues it was deprived of a valuable property interest in
its business without due process.7 Key Medical advances these arguments in an effort
to obtain review under a constitutional-claim exception to the statutory bar on review.
  See, e.g., McNary v. Haitian Refugee Ctr., Inc., 

, 495 (1991)

        Key Medical's arguments concerning the interplay of the competitive bidding
system with the separate Minnesota Medicaid system are similarly without merit. In
this regard, Key Medical identifies a consequence of the competitive bidding system
rather than a clearly ultra vires aspect of the system or its implementation. Congress
did not mandate that the Agency avoid or even consider the impact upon state
Medicaid systems in design and implementation of the competitive bidding system.
We therefore make no comment as to the merit of Key Medical's claims of unfairness
and unintended consequences. We note merely that our inquiry is limited to whether
the Agency acted in such derogation of its authority as to act in an ultra vires matter
that might permit our Court to exercise jurisdiction notwithstanding the bar on
review.

      Key Medical does not fully articulate distinct arguments, instead blending the
concepts of due process rights and protections against takings into one.

of federal jurisdiction is "patently meritless" however, a plaintiff cannot avoid
application of a bar on review. See Biscann v. Merrill Lynch & Co.,

        Here, Key Medical possesses no protected interest that can serve as the basis
for a takings claim, nor a property interest that may serve as the basis of a due process
violation. In Minnesota Association of Health Care Facilities, Inc. v. Minnesota
Department of Public Welfare, 

, 446 (8th Cir. 1984), the Eighth Circuit
rejected a plaintiff's attempt to characterize a loss of business associated with a
condition on Medicaid participation as a taking. There, the court stated, "[d]espite
the strong financial inducement to participate in Medicaid," the care provider's choice
to participate in Medicaid was "nonetheless voluntary."

establishing new reimbursement payment regime and as such no "substantial

Because the constitutional claim lacks merit due to the absence of a protected
property or liberty interest, it is not "a substantial constitutional challenge" capable
of overcoming the bar on review. Am. Soc'y of Cataract & Refractive
