    Opinion for the Court filed by Circuit Judge WILKINS.
    WILKINS, Circuit Judge: Appellants are four long-term
    care hospitals located in North Carolina, Pennsylvania, Texas,
    and Louisiana. The hospitals treat patients who are dually
    eligible for the Medicare and Medicaid programs. In 2008, the
    hospitals were denied reimbursement by the Secretary of
    Health and Human Services for “bad debts”—i.e., unpaid
    coinsurances and deductibles owed by patients. The Secretary
    denied reimbursement on the grounds that the hospitals failed
    to comply with the “must-bill” policy, which requires providers
    to first seek payment from Medicaid before seeking
    reimbursement from Medicare for the bad debts of patients
    covered by both programs. The hospitals sought judicial
    review of the reimbursement denial, and the District Court
    granted summary judgment to the Secretary. For the reasons
    explained below, we affirm the District Court.
    I
    A
    Medicare is a federally funded program that reimburses
    healthcare providers for delivering medical care to qualifying
    elderly and disabled individuals. See 42 U.S.C. § 1395 et seq.
    Medicaid is a cooperative federal-state program—administered
    by states, and subject to federal guidelines—that pays for
    medical care provided to eligible low-income individuals. See
    42 U.S.C. § 1396 et seq. Medicare is administered by the
    Centers for Medicare and Medicaid Services (“CMS”) on
    behalf of the Secretary of Health and Human Services.
    Notably, because Medicare does not cover the full cost of care,
    patients are responsible for paying deductible and coinsurance
    fees for inpatient hospital services received. See 42 U.S.C. §
    1395e; 42 C.F.R. §§ 409.82, 409.83.
    3
    This case concerns several hospitals that treat “dual-
    eligible” patients—i.e., individuals who qualify for both
    Medicare and Medicaid. Often, these patients are unable to
    afford the coinsurances and deductibles required of them under
    Medicare. When that happens, state Medicaid programs may
    fill the gap by requiring the state Medicaid agency to cover the
    unpaid fees. Grossmont Hosp. Corp. v. Burwell, 
    797 F.3d 1079
    , 1081 (D.C. Cir. 2015). The Medicaid statute requires
    states to determine what cost-sharing liability they bear for
    dual-eligible patients. See 42 U.S.C. § 1396a(a)(10)(E)(i).
    If the state does not cover the deductibles and coinsurances
    of dual-eligible patients through Medicaid, then those missing
    payments can be designated as “bad debts,” and healthcare
    providers can seek reimbursement through Medicare. See 42
    C.F.R. § 413.89; see also CMS Provider Reimbursement
    Manual Part 1, § 322, https://www.cms.gov/Regulations-and-
    Guidance/Guidance/Manuals/Paper-Based-Manuals-
    Items/CMS021929. Medicare reimburses bad debts to prevent
    hospitals from shifting the cost of Medicare-related services
    onto non-Medicare patients. See 42 U.S.C. § 1395x(v)(1)(A)
    (requiring the Secretary to regulate in such a way that “the
    necessary costs of efficiently delivering covered services to
    individuals covered by the insurance programs established by
    this subchapter will not be borne by individuals not so
    covered”).
    Before a provider can seek reimbursement of bad debt
    from Medicare, CMS requires the provider to demonstrate that
    “reasonable . . . efforts were made” to collect payment from the
    party responsible for the bill. 42 C.F.R. § 413.89(e)(2). In its
    Provider Reimbursement Manual (“PRM”), CMS explains
    what a “reasonable collection effort” means. See Provider
    Reimbursement Manual § 310. Section 310 of the PRM
    explains that providers must “issu[e] . . . a bill . . . to the party
    responsible” for the patient’s payments. CMS Provider
    4
    Reimbursement Manual § 310. Section 322 of the PRM further
    explains that when a state Medicaid program is “obligated
    either by statute or under the terms of its plan to pay all, or any
    part, of the Medicare deductible or coinsurance amounts, those
    amounts are not allowable as bad debts under Medicare.” Id.
    § 322 (emphasis added). Medicare thus allows “[a]ny portion
    of such deductible or coinsurance amounts that the State is not
    obligated to pay [to] be included as a bad debt[.]” Id.
    (emphasis added).
    CMS addressed the bad debt reimbursement policy in a
    joint memorandum (“JSM”) issued to all fiscal intermediaries
    in 2004. At that time, CMS explained that:
    In order to fulfill the requirement that a provider
    make a “reasonable” collection effort with
    respect to the deductibles and co-insurance
    amounts owed by dual-eligible patients, our bad
    debt policy requires the provider to bill the
    patient or entity legally responsible for the
    patient’s bill before the provider can be
    reimbursed for uncollectible amounts.
    J.A. 238. The 2004 memorandum referred to this pre-
    reimbursement requirement as the “must-bill” policy, and it
    outlined the steps a provider must take to comply with the
    policy before seeking bad debt reimbursement for dual-eligible
    patients:
    [I]n those instances where the state owes none
    or only a portion of the dual-eligible patient’s
    deductible or co-pay, the unpaid liability for the
    bad debt is not reimbursable to the provider by
    Medicare until the provider bills the State, and
    the State refuses payment (with a State
    Remittance Advice).
    5
    Id. In short, CMS’s must-bill policy requires hospitals to: (1)
    bill the state Medicaid program to determine whether Medicaid
    will cover the bad debts first, and (2) obtain a document known
    as a “remittance advice” (“RA”) indicating whether the state
    “refuses payment,” before seeking reimbursement under
    Medicare. Id.; see also Grossmont, 797 F.3d at 1086.
    Bad debt reimbursement claims are ultimately processed
    by private insurance companies (fiscal intermediaries) serving
    as contractors for CMS. See 42 U.S.C. §§ 1395h(a), 1395u(a),
    1395kk-1. Healthcare providers file annual cost reports with
    these contractors, 42 C.F.R. § 413.20(b), and the contractors
    issue notices indicating which payments Medicare will cover,
    id. § 405.1803(a). Providers can then appeal reimbursement
    decisions from the contractors to the Provider Reimbursement
    Review Board (“Board”), an administrative tribunal within
    HHS. 42 U.S.C. § 1395oo(a). The Board’s decision is final
    unless     the    Secretary—acting      through     the   CMS
    Administrator—“reverses, affirms, or modifies” the Board. Id.
    § 1395oo(f)(1); see also 42 C.F.R. § 405.1875(a). From there,
    a provider may seek judicial review by filing a civil action in
    district court. 42 U.S.C. § 1395oo(f); 42 C.F.R. § 405.1877(b).
    Relevant here, Congress froze any changes to CMS’s bad
    debt reimbursement policy in 1987. Grossmont, 797 F.3d at
    1083; see also Omnibus Budget Reconciliation Act of 1987,
    Pub. L. No. 100-203, § 4008(c), 101 Stat. 1330–55. This
    freeze, known as the “Bad Debt Moratorium,” prevents CMS
    from making “any change in the policy in effect on August 1,
    1987, with respect to payment” for “unpaid deductible and
    coinsurance amounts.” Pub. L. No. 100-203, § 4008(c).
    B
    Appellants (“the hospitals”) are long-term care facilities in
    North Carolina, Pennsylvania, Texas, and Louisiana. In April
    2008, the hospitals were denied over $3 million in bad debt
    6
    reimbursement claims they submitted to CMS contractors. The
    contractors denied the claims on the grounds that the hospitals
    failed to comply with the must-bill policy. During the relevant
    time period, the hospitals were not enrolled in Medicaid and
    were thus unable to bill their respective state Medicaid
    programs. Central to this appeal, the hospitals claim that CMS
    contractors previously reimbursed bad debt claims without
    requiring proof that the hospital followed the must-bill policy.
    According to the hospitals, contractors only began enforcing
    the policy against them in April 2008.
    The hospitals appealed the denial of reimbursement to the
    Board. The Board upheld the contractors’ decisions for half of
    the hospitals, but reversed as to the other half. With respect to
    the hospitals in Louisiana and Texas, the Board found that they
    had “made a business decision” not to enroll in Medicaid, and
    that nothing prevented them from complying with the must-bill
    policy except for their own decision not to enroll in Medicaid.
    As to the hospitals in North Carolina and Pennsylvania, the
    Board found that those hospitals were not permitted to enroll
    in their state Medicaid programs during the relevant period, and
    were thus unable to bill Medicaid through no fault of their own.
    As a result, the Board ordered the contractors to accept an
    alternative form of documentation (something other than the
    RA) and reconsider the reimbursement claims.
    The CMS Administrator took up review of the Board’s
    decision. The parties filed comments for the Administrator, see
    42 C.F.R. § 405.1875, but the hospitals failed to raise one
    argument at issue in this appeal—namely, that CMS violated
    Congress’s 1987 Bad Debt Moratorium by suddenly enforcing
    the must-bill policy in 2008.
    The Administrator partially reversed the Board and denied
    all of the hospitals’ reimbursement claims. The Administrator
    reasoned that the must-bill policy applies to all hospitals,
    regardless of Medicaid enrollment status, because state
    7
    Medicaid programs are required to allow limited enrollment for
    the purpose of complying with the must-bill policy. J.A. 729–
    30. The Administrator also noted that if a state refuses to allow
    a hospital to enroll and thereby comply with the must-bill
    policy, then the hospital’s recourse is to “take legal action with
    the[] state[].” J.A. 730.
    The hospitals filed suit in the District Court, raising several
    challenges to CMS’s application of the must-bill policy. The
    hospitals did not challenge the must-bill policy per se. J.A.
    109. Rather, they challenged CMS’s sudden enforcement of
    the policy in April 2008—an enforcement which they claim
    violated the Medicare Act, the Administrative Procedure Act,
    and the Bad Debt Moratorium. J.A. 30–32.
    The parties cross-moved for summary judgment. The
    District Court granted summary judgment to the Secretary,
    finding that most of the hospitals’ challenges failed because the
    hospitals did not prove CMS changed its application of the
    must-bill policy. The District Court also declined to reach the
    hospitals’ argument that CMS violated the Bad Debt
    Moratorium, because the hospitals did not raise it before the
    Administrator.       The hospitals filed a motion for
    reconsideration, arguing that it was both clear error and
    fundamentally unfair to preclude judicial review of a claim not
    presented to the Administrator so long as the claim was
    developed before the Board. After a hearing, the District Court
    denied the motion, holding again that the hospitals waived the
    Bad Debt Moratorium argument by failing to present it at all
    stages of administrative review. The hospitals timely appealed.
    II
    The hospitals argue that the Administrator’s decision was
    unlawful for several reasons, and they ask us to reverse the
    District Court’s grant of summary judgment to the Secretary.
    We review de novo the District Court’s summary judgment
    8
    decision. Grossmont, 797 F.3d at 1082. But because the
    District Court reviewed an administrative decision, “our task is
    the same as that performed by the district judge. In other words,
    we review the administrative record to determine whether the
    agency’s decision was arbitrary and capricious, and whether its
    findings were based on substantial evidence.” Forsyth Mem’l
    Hosp., Inc. v. Sebelius, 
    639 F.3d 534
    , 537 (D.C. Cir. 2011)
    (citing Troy Corp. v. Browner, 
    120 F.3d 277
    , 281 (D.C. Cir.
    1997)). We ask whether the agency “examine[d] the relevant
    data and articulate[d] a satisfactory explanation for its action
    including a rational connection between the facts found and the
    choice made.” Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. State
    Farm Mut. Auto. Ins. Co., 
    463 U.S. 29
    , 43 (1983) (internal
    quotation marks omitted).
    According to the hospitals, CMS abruptly changed its
    policy and began enforcing the must-bill requirement against
    the hospitals in April 2008, resulting in the denial of $3 million
    in reimbursement claims. The hospitals contend that this
    sudden enforcement violated the Medicare Act and the APA.
    We address each argument in turn.
    A
    The hospitals first argue that the Administrator’s decision
    violated the Medicare Act, 42 U.S.C. § 1395hh(a)(2). They
    reason that the sudden enforcement of the must-bill policy in
    April 2008 amounted to an interpretive rule, and the Medicare
    Act requires notice-and-comment rulemaking for changes in
    interpretive rules. See Azar v. Allina Health Servs., 
    139 S. Ct. 1804
    , 1814 (2019) (holding that the Medicare Act does not
    incorporate the APA’s exception to notice-and-comment
    rulemaking for interpretive rules).1 The hospitals also argue
    1
    The Medicare Act, 42 U.S.C. § 1395oo(f)(1), incorporates the
    APA’s standard of review. See Thomas Jefferson Univ. v. Shalala,
    
    512 U.S. 504
    , 512 (1994).
    9
    that this interpretive rule was arbitrary and capricious under the
    APA, because it represented an abrupt change in policy with
    no reasoned explanation. See FCC v. Fox Television Stations,
    Inc., 
    556 U.S. 502
    , 515 (2009).
    The problem for the hospitals is that they identify no
    change in CMS policy taking place in 2008. As noted above,
    CMS outlined its must-bill policy in a 2004 joint memorandum
    (“JSM”) sent to all intermediary contractors. The hospitals do
    not challenge that memorandum; at oral argument, counsel for
    the hospitals explained that the only challenge here is to CMS’s
    “decision to impose the remittance advice requirement on [the
    hospitals] beginning in April 2008.” Oral Arg. Recording
    5:45–6:05. The hospitals presume that CMS somehow altered
    the must-bill policy in 2008 or issued a new interpretive rule
    suddenly enforcing the policy against them, but the
    Administrator determined otherwise based on the record.
    First, the Administrator found that there was no evidence
    of a change in agency policy in 2008: Prior to 2008, “no
    statement in the JSM, related PRM sections, or prior
    Administrator decisions” exempted the hospitals from the
    must-bill policy. J.A. 731. Second, the Administrator found
    that intermediary contractors may have reimbursed bad debts
    in the past without enforcing the must-bill policy (“without
    [requiring] appropriate documentation”), but even so, the
    actions of contractors did not set agency policy. 
    Id.
     In other
    words, a failure by contractors to properly enforce the must-bill
    policy against the hospitals in years past did “not constitute an
    explicit or affirmative agency action on policy.” 
    Id.
     The
    Administrator found that even if the hospitals were previously
    reimbursed without adhering to the must-bill policy, evidence
    of those reimbursements was consistent with the conclusion
    that the contractors must have erred when reviewing and
    auditing previous claims. See 
    id.
     As the Administrator
    explained: “[I]t is not always possible to review every item of
    10
    the cost report every year . . . . Such an error also does not
    demonstrate that CMS has abandoned or changed a policy.” 
    Id.
    The Administrator concluded that prior failures of contractors
    did not “relieve [a hospital] of its responsibility to follow the
    rules and regulations of CMS.” 
    Id.
    On appeal, the hospitals point to nothing in the record to
    undermine the Administrator’s determination. Instead, the
    hospitals assume that the actions of contractors signaled a
    change in agency policy in 2008. See Appellants’ Br. at 15
    (referring to “CMS’s change in interpretation of the must-bill
    policy”); 
    id. at 16
    –19 ( “CMS changed a substantive legal
    standard . . . .”); 
    id. at 23
     (“CMS abruptly changed its policy
    . . . .”). Here, as in the District Court, the hospitals rely
    primarily upon a set of statements from their Vice President for
    Reimbursement, who testified that “[p]rior to the years at issue,
    the intermediaries did not require . . . an RA,” and “that was
    the audit treatment up until April of 2008.” J.A. 616. The Vice
    President also stated that contractors “started requiring a valid
    . . . RA with a valid denial code” in April 2008, 
    id.,
     and even
    though CMS issued a joint memorandum outlining the must-
    bill policy in 2004, the contractors “accepted documentation
    just supporting Medicaid eligibility” between 2004 and 2008,
    
    id. at 618
    . The hospitals also cite a letter sent by the hospitals
    to an auditor in March 2008 with alternative documentation
    (not an RA), along with redacted copies of forms showing
    patient Medicaid eligibility. See Appellants’ Br. at 21; J.A.
    298. None of this evidence undermines the Administrator’s
    finding: While contractors may have failed to properly audit
    the hospitals’ must-bill compliance before April 2008, those
    errors do not amount to a change in CMS policy.
    In addition, the hospitals argue that the District Court
    should have followed Select Specialty Hospital-Denver, Inc. v.
    Azar, 
    391 F. Supp. 3d 53
     (D.D.C. 2019). In Select, the district
    court held that CMS was “required, under the Medicare Act . .
    11
    . to conduct notice-and-comment rulemaking” before imposing
    the “must-bill policy and the RA requirement” on a group of
    “non-Medicaid-participating providers.” 391 F. Supp. 3d at 67.
    There, as here, a group of hospitals that participated in
    Medicare but not Medicaid challenged the denial of their
    reimbursement claims for dual-eligible bad debts. Id. at 55. On
    cross-motions for summary judgment, the district court held for
    the hospitals. Id. at 56. But Select involved a different
    administrative record. As the District Court correctly noted
    here, its review of the Administrator’s decision is “limited [to]
    and confined by the record in front of it.” New LifeCare Hosps.
    of N. Carolina LLC v. Azar, 
    416 F. Supp. 3d 11
    , 22 (D.D.C.
    2019), reconsideration denied, 
    466 F. Supp. 3d 124
     (D.D.C.
    2020). “It is black-letter administrative law that in an
    Administrative Procedure Act case, a reviewing court should
    have before it neither more nor less information than did the
    agency when it made its decision.” CTS Corp. v. EPA, 
    759 F.3d 52
    , 64 (D.C. Cir. 2014) (internal quotation marks and brackets
    removed). The record before us does not indicate a change in
    agency policy in 2008.
    Because we conclude that the Administrator’s finding of
    no change in CMS policy was supported by substantial
    evidence, we reject the hospitals’ arguments that CMS violated
    the Medicare Act or the APA by changing an interpretive rule
    in 2008.
    B
    The hospitals next argue that the District Court should
    have considered whether the Administrator’s decision violated
    the Bad Debt Moratorium. The District Court held that this
    issue was waived by the hospitals’ failure to exhaust it at the
    administrative level, because the hospitals did not raise the
    argument to the Administrator despite raising it before the
    Board.
    12
    As noted above, the must-bill policy has two requirements:
    1) a requirement to bill the state Medicaid agency, and 2) a
    requirement to obtain an RA. Here, the Board found that the
    first requirement predates the Bad Debt Moratorium, and the
    Board declined to reach whether the second requirement
    violates the Moratorium. See J.A. 707 (“[T]he Board finds that
    pre-1987 bad debt policy in the PRM clearly established that
    providers have an obligation to bill ‘the responsible party.’”);
    J.A. 709 n.49 (citing “examples of pre-1987 agency statements
    and Board cases applying CMS’ bad debt policy”); J.A. 709
    n.48 (“[T]he Board need not address . . . whether the CMS’
    position that the ‘must bill’ policy necessarily includes
    obtaining an RA from a state even when that state has no
    responsibility violates the Bad Debt Moratorium.”). The
    Board’s finding was not disturbed by the Administrator.
    Although the Administrator provided several reasons for
    denying the hospitals’ claims, at least one of the reasons was
    the hospitals’ “failure to timely bill the State.” J.A. 729; see
    also J.A. 728 (“[T]here are two types of situation[s] under
    which the Providers did not bill and receive a remittance advice
    from the respective State in which they were located in this
    case.” (emphasis added)); see also J.A. 726 (citing Cmty. Hosp.
    of Monterey Peninsula v. Thompson, 
    323 F.3d 782
     (9th Cir.
    2003), and noting that “unpaid liability for the bad debt is not
    reimbursable until the provider bills the State and the State
    refuses payment, all of which is demonstrated through a
    Remittance Advice”).
    On appeal, the hospitals do not argue that the billing
    requirement in fact violates the Moratorium. Rather, they
    argue that the RA requirement—the second half of the must-
    bill policy—violates the Moratorium, and that the District
    Court should have addressed this issue. See Appellants’ Br. at
    28. But the Government points out that we need not reach this
    issue, because the hospitals never complied with the billing
    requirement which the Board found predates 1987. Gov’t Br.
    13
    at 24–26. In their reply brief, the hospitals argue they did
    properly comply with the billing requirement. See Appellants’
    Reply Br. at 17, 23. This argument is not timely, not only
    because it first appears in the reply brief, but also because it
    was not raised in the District Court, as it is not our role to
    resolve a factual dispute on appeal. “[W]e are a court of
    review, not of first view.” Capitol Servs. Mgmt., Inc. v. Vesta
    Corp., 
    933 F.3d 784
    , 789 (D.C. Cir. 2019) (internal quotation
    marks and brackets omitted).
    The hospitals correctly note that other district courts have
    found the RA requirement violates the Bad Debt Moratorium
    based on different administrative records. See Kindred
    Healthcare, Inc. v. Azar, No. 1:18-cv-650, 
    2020 WL 3574614
    ,
    at *8 (D.D.C. July 1, 2020); Select, 391 F. Supp. 3d at 59,
    reconsideration denied, No. 1:10-cv-1356, 
    2019 WL 5697076
    (D.D.C. Nov. 4, 2019), appeal dismissed, No. 20-5004, 
    2020 WL 768266
     (D.C. Cir. Jan. 28, 2020) (“The Secretary cites
    nothing in the record articulating an absolute RA requirement
    before the issuance of JSM-370 . . . .”); Mercy Gen. Hosp. v.
    Azar, 
    410 F. Supp. 3d 63
    , 77 (D.D.C. 2019). But we agree with
    the Government that these cases are inapplicable given the
    record before us. Here, the Board found that the hospitals did
    not comply with the billing requirement that predates the
    Moratorium, and the hospitals have not pointed to anywhere in
    the record where they challenged these findings for lack of
    substantial evidence. Under the circumstances of this case, the
    District Court did not need to address whether the RA
    requirement violates the Bad Debt Moratorium.2

    The hospitals also argue that the District Court made this Bad Debt
    Moratorium argument reviewable by ordering the hospitals to
    address, in a sur-reply, “whether the must-bill policy, both generally
    and as applied to non-Medicaid-participating providers, violates the
    Bad Debt Moratorium.” Minute Order, New LifeCare Hosps. Of N.
    Carolina LLC v. Cochran, No. 1:17-cv-237 (D.D.C. July 26, 2019)

    C
    The hospitals’ remaining arguments fare no better. First,
    the hospitals contend that the Administrator’s decision violated
    Medicare’s prohibition against cost-shifting. As noted above,
    the Medicare Act prohibits shifting costs of Medicare services
    onto non-Medicare patients. It also prohibits shifting costs
    from non-Medicare services onto the Medicare program. See
    42 U.S.C. § 1395x(v)(1)(A) (“[T]he necessary costs of
    efficiently delivering covered services to individuals covered
    by the insurance programs established by this subchapter will
    not be borne by individuals not so covered, and the costs with
    respect to individuals not so covered will not be borne by such
    insurance programs[.]”).       The hospitals argue that the
    Administrator’s decision to deny them over $3 million in
    reimbursement for Medicare patients violates this anti-cost-
    shifting provision.
    We agree with the District Court that this argument
    amounts to a claim that “the Administrator [cannot] deny any
    bad debt reimbursement claims—no matter how frivolous.”
    New LifeCare Hosps., 416 F. Supp. 3d at 18. And we decline
    to adopt that reading of the anti-cost-shifting provision. While
    the Medicare Act prohibits shifting costs onto non-Medicare
    patients, it also “authoriz[es] the Secretary to refuse to
    reimburse costs when the provider has failed to ‘furnish such
    information as the Secretary may request in order to determine
    the amounts due such provider.’” Id. (citing 42 U.S.C. §
    1395g(a) (emphasis added)).
    (emphasis added). It is unclear why the District Court ordered the
    sur-reply, but the hospitals do not challenge the “must-bill policy
    . . . generally,” and the District Court ultimately noted that in its
    opinion. See New LifeCare Hosps., 416 F. Supp. 3d at 18. The
    hospitals challenge only the April 2008 decision on their
    reimbursement claims.
    15
    Second, the hospitals argue that the Administrator’s
    decision impermissibly requires them to enroll in Medicaid,
    despite the fact that Medicaid participation is voluntary. But,
    as the Government notes, Medicare participation is also
    voluntary. Here, the Administrator explained that the decision
    of a provider not to enroll in Medicaid does not relieve a state
    of its responsibility to share the costs of dual-eligible patients’
    bad debts. See J.A. 729 (“The non-Medicaid enrollment status
    of a provider does not change the legal responsibilities that
    result from the dual eligible status of a Medicare beneficiary
    for which a State may be liable for cost sharing[.]”). If a
    hospital treats dual-eligible patients, incurs bad debts, and
    seeks reimbursement of those debts from Medicare, then the
    hospital must contend with the statutory and regulatory
    requirements for obtaining reimbursement. See, e.g., 42 U.S.C.
    § 1396a(a)(10)(E)(i) (requiring a state Medicaid plan to
    provide “for making medical assistance available for
    [M]edicare cost-sharing (as defined in section 1396d(p)(3) of
    this title) for qualified [M]edicare beneficiaries”). We do not
    mean to understate the practical burden on the hospitals here,
    but as the Administrator’s decision explained, these
    requirements stand apart from—and do not dictate—a
    provider’s decision to participate in Medicaid.
    Third, the hospitals contend that the Administrator’s
    decision was arbitrary and capricious or unsupported by
    substantial evidence for a few reasons. They argue that the
    Administrator failed to consider that the hospitals had “no way
    to comply with CMS’s new interpretation of the must-bill
    policy” because they were prevented from enrolling in
    Medicaid by certain states. Appellants’ Br. at 47–48. But the
    Administrator considered this argument and reasonably
    explained its reasons for rejecting it. J.A. 728 (“[N]one of the
    Providers were enrolled in Medicaid. The Providers alleged
    they could not conform to the [m]ust bill policy . . . .”).
    Specifically, the Administrator noted that states are obligated
    16
    by the Medicaid statute to process claims for dual-eligible
    patients and to determine their cost-sharing liability for those
    patients. J.A. 730. As a result, the Administrator concluded
    that providers should “take legal action with their states” if a
    state prohibits enrollment for the purpose of dual-eligible
    billing. Id. Most importantly, the Administrator found that
    even in the two states where the hospitals were previously
    excluded from Medicaid enrollment, those states permitted
    enrollment “in order to bill and receive RAs” after the hospitals
    “reach[ed] out and explain[ed] the circumstances to NC and PA
    State officials.” J.A. 730. Thus, while it was “no doubt
    frustrating” for the hospitals to enroll in Medicaid, it was not
    impossible. New LifeCare Hosps., 416 F. Supp. 3d. at 23.
    Next, the hospitals claim it was arbitrary and capricious
    for the Administrator to require compliance with the must-bill
    policy by some providers while certain other providers are
    exempt from the policy. Specifically, the hospitals point to
    community mental health centers in California which are
    exempt from bad debt billing because the state does not license
    them, and they are thus unable to enroll in Medicaid. The
    hospitals also point to institutions for mental disease (“IMDs”),
    which receive an exemption from the bad debt policy. See id.
    at 23–24. But the Administrator reasonably explained why
    these exemptions differ from the hospitals’ case. Unlike the
    California community mental health centers, the hospitals are
    licensed by their states. J.A. 732. Also unlike the hospitals,
    the IMDs serve patients who, due to age, are excluded from
    Medicaid payments by statute and regulation. Id.; see also 42
    U.S.C. § 1396d(a)(14); 42 C.F.R. §§ 435.1009(a)(2),
    441.13(a)(2). The hospitals, in contrast, are capable of
    enrolling in Medicaid and obtaining reimbursement for their
    patients’ bad debts under the terms of the must-bill policy.
    The hospitals’ final arbitrary-and-capricious claims fail for
    the same reasons addressed above. They contend that the
    17
    Administrator’s decision was arbitrary and capricious because
    it departed from how CMS treated reimbursement requests
    before April 2008. But again, the hospitals cite only to their
    own Vice President’s testimony about reimbursements
    received before 2008—and as the Administrator found, this
    evidence did not establish that CMS changed policy in 2008.
    The hospitals’ final argument, relying on FCC v. Fox
    Television, is that CMS changed a policy or past practice on
    which the hospitals had relied, because CMS “consistently
    exempted Hospitals from its must-bill policy” in years past.
    Appellants’ Br. at 54; see also Fox Television, 
    556 U.S. at 515
    .
    The Administrator found no such exemption in the record, and
    as explained above, the hospitals have pointed to nothing to
    undermine the Administrator’s determination. See J.A. 731.
    We therefore conclude that the Administrator’s decision was
    not arbitrary and capricious.
    III
    For the foregoing reasons, we affirm the judgment of the
    District Court.
    So ordered.
