    OPINION OF THE COURT
    GREENBERG, Circuit Judge.
    I.   INTRODUCTION
    This matter comes on before this Court on an appeal by Mercy
    Home Health (“MHH”) from an order of the district court entered
    March 18, 2005, granting summary judgment in favor of the Secretary
    of Health and Human Services (the “Secretary”). MHH sought
    review in the district court of the Secretary’s final decision denying
    certain Medicare reimbursements for home office costs that MHH
    claimed pursuant to an alternative cost allocation method previously
    approved by the Medicare fiscal intermediary. For the reasons set
    forth below, we will affirm.
    II.   FACTUAL AND PROCEDURAL HISTORY
    A. Medicare Reimbursement
    Under Title XVII of the Social Security Act (the “Medicare
    Act”), 42 U.S.C. § 1395 et seq., the Secretary administers the
    2
    Medicare program through the Centers for Medicare and Medicaid
    Services (“CMS”).1 Most Medicare providers receive reimbursement
    through fiscal intermediaries (“intermediaries”) for services provided
    to Medicare beneficiaries. Intermediaries contract with the Secretary
    to determine the amounts due and are bound by the Secretary's
    regulations and interpretive rules. See 42 U.S.C. §§ 1395h, 1395kk-
    1; 42 C.F.R. § 421.100.
    Congress authorized the Secretary “to promulgate regulations
    ‘establishing the method or methods to be used’ for determining
    reasonable costs.” Shalala v. Guernsey Mem’l Hosp., 
    514 U.S. 87
    ,
    91-92, 
    115 S. Ct. 1232
    , 1235 (1995) (citing 42 U.S.C. §
    1395x(v)(1)(A)). The Secretary’s implementing regulations define
    “reasonable cost” as including reimbursement of only “necessary and
    proper” costs for furnishing covered services related to beneficiary
    care. 42 C.F.R. § 413.9(a). During the time period at issue,
    Medicare reimbursed home health agencies based on their “cost
    actually incurred,” less any costs “unnecessary in the efficient
    delivery of needed health services.” 42 U.S.C. § 1395x(v)(1)(A).
    1. Prohibition on Cross-Subsidization
    The Medicare Act requires the Secretary’s regulations to “take
    into account both direct and indirect costs of providers of services,”
    and to ensure that Medicare does not pay costs of non-Medicare
    patients, and that other insurance programs do not pay the costs of
    Medicare patients. 
    Id. To prevent
    cross-subsidization, the act further
    directs the Secretary to “provide for the making of suitable retroactive
    corrective adjustments where . . . the aggregate reimbursement
    produced by the methods of determining costs proves to be either
    inadequate or excessive.” 
    Id. 2. Record
    Keeping Requirements
    Because the Secretary must verify the provider’s actual costs
    to ensure proper payment, “[i]t is hardly surprising that the
    reimbursement process begins with certain record keeping
    requirements.” Guernsey Mem’l 
    Hosp., 514 U.S. at 94
    , 115 S.Ct. at
    1236. To this end, the Medicare Act provides that “no such payments
    shall be made to any provider unless it has furnished such information
    1
    CMS formerly was known as the Health Care Financing
    Administration (“HCFA”).
    3
    as the Secretary may request in order to determine the amounts due
    such provider” for the cost period at issue. 42 U.S.C. § 1395g(a).
    The implementing regulations further state that “[p]roviders receiving
    payment on the basis of reimbursable cost must provide adequate cost
    data.” 42 C.F.R. § 413.24(a). According to the regulations, the data
    must be “accurate and in sufficient detail to accomplish the purposes
    for which it was intended,” and the data must be auditable. 
    Id. at §
    413.24(c).
    3. Cost Allocation
    The home office of a chain of commonly-owned health care
    providers is not a Medicare provider and cannot directly receive
    Medicare reimbursement. See 42 U.S.C. § 1395cc. Nevertheless,
    inasmuch as home offices may perform certain centralized services
    for a provider subsidiary, Medicare treats those support services as
    though “obtained from [the provider] itself.” 42 C.F.R. §
    413.17(c)(2). The Secretary’s interpretive rules, found in the
    Provider Reimbursement Manual, CMS Pub. 15-1 (“PRM”), address
    how a provider may obtain reimbursement for home office support
    functions.
    To obtain reimbursement for home office support functions
    related to the care of Medicare patients, the provider’s home office
    files a cost statement, which identifies the allowable home office
    costs and how they are allocated among each of its subsidiary
    companies (also called “components”). See PRM § 2150.3. First, the
    home office totals all of its own costs, including those that it incurred
    on behalf of its subsidiary companies, and deletes from that total all
    unallowable costs. See 
    id. at §
    2150.3(A). Second, the home office
    uses “direct allocation” to allocate as many of its costs as possible.
    Direct allocation accounts for home office costs that are for the
    benefit of, or directly attributable to, its Medicare subsidiary or its
    other subsidiaries. See 
    id. at §
    2150.3(B). Third, the home office
    must allocate as many of the remaining costs as possible on a
    “functional basis.” See 
    id. at §
    2150.3(C).
    After the home office allocates as many home office costs as
    possible to its subsidiaries by direct and functional allocation, a
    “pool” of allowable costs for general management or administrative
    services remains (“pooled costs”). See 
    id. at §
    2150.3(D). If the
    chain consists of companies providing health care services and other
    types of companies, all the companies “share in the pooled home
    office costs in the same proportion that the total costs of each
    4
    component (excluding home office costs) bear to the total costs of all
    components in the chain.” 
    Id. at §
    2150.3(D)(2)(b). Thus, the CMS-
    prescribed default methodology for allocating pooled costs is a cost-
    to-total cost allocation methodology.
    If a home office has higher costs for one of its non-Medicare
    providers, but performs few services for that company, the home
    office may use a more sophisticated alternative allocation method to
    allocate the pooled costs more precisely. See 
    id. at §
    2150.3(D)(2)(b).
    The PRM specifies the procedure the home office should follow if it
    wants to use an alternative allocation method:
    If evidence indicates that the use of a more
    sophisticated allocation basis would provide a more
    precise allocation of pooled home office costs to the
    chain components, such basis can be used in lieu of
    allocating on the basis of either inpatient days or total
    costs. However, intermediary approval must be
    obtained before any substitute basis can be used. The
    home office must make a written request with its
    justification to the intermediary responsible for
    auditing the home office cost for approval of the
    change . . . .
    Where the intermediary approves the home office
    request, the change must be applied to the accounting
    period for which the request was made, and to all
    subsequent home office accounting periods, unless the
    intermediary approves a subsequent change for the
    home office.
    
    Id. 4. Cost
    Reconciliation and Review
    The Medicare Act requires payments to providers, at least
    monthly, based on estimated costs. See 42 U.S.C. § 1395g(a). The
    act also requires the Secretary to establish a process to reconcile
    estimated payments made with the actual amount due and requires
    that regulations create a reconciliation process. See 
    id. at §
    1395x(v)(1)(A).
    The provider initiates the cost reconciliation process by filing
    an annual cost report with the intermediary. See 42 C.F.R. §
    5
    413.20(b). The intermediary audits the cost report, see 
    id. at §
    421.100(c), and issues a notice of program reimbursement (“NPR”),
    which informs the provider of the amount of reimbursement due for
    Medicare services during that fiscal year, 
    id. at §
    405.1803. The
    intermediary then adjusts ongoing payments to account for
    overpayments or underpayments. See 42 U.S.C. § 1395g(a). To
    further ensure that intermediaries correctly reimburse Medicare
    providers, the Secretary’s regulations allow intermediaries to reopen
    cost determinations within three years of the date of the NPR. See 42
    C.F.R. § 405.1885(a). Intermediaries must reopen a determination if
    CMS notifies them that an NPR is inconsistent with applicable law,
    regulations, or CMS general instructions. See 
    id. at §
    405.1885(b)(1)(i); see also PRM § 2931.2.
    If the provider is dissatisfied with the intermediary’s
    determination and meets the amount in controversy requirement, the
    provider may appeal to the Secretary’s Provider Reimbursement
    Review Board (“PRRB”). See 42 U.S.C. § 1395oo(a); 42 C.F.R. §
    405.1835; see also 42 C.F.R. § 405.1889 (providing that intermediary
    determinations after reopening are subject to appeal). The PRRB may
    hold a hearing and issue a decision that is subject to further review by
    the Secretary’s delegate, the CMS Administrator. See 42 U.S.C. §
    1395oo(f)(1); 42 C.F.R. § 405.1875. The CMS Administrator may
    decline to review or may, affirm, reverse, modify or remand a PRRB
    decision. See 42 C.F.R. § 405.1875(d)(2), (g)(1). The final decision
    of the Secretary (issued by the PRRB or the CMS Administrator), is
    subject to judicial review. See 42 U.S.C. § 1395oo(f)(1).
    B. Factual Background
    MHH is Mercy Home Health Services’ (the “Home Office”)
    only Medicare provider subsidiary.2 On July 12, 1993, the Home
    Office sent a letter to its fiscal intermediary, Independence Blue
    Cross, requesting permission to use an alternative allocation method
    for the pooled home office costs of its various chain components. The
    letter stated, “[s]ince the majority of our business is service oriented,
    the costs in the [H]ome [O]ffice should be largely allocated to those
    2
    During the period at issue, the Home Office had four
    subsidiaries: (1) MHH, the sole Medicare provider; (2) a private duty
    home nursing agency; (3) a home health care staffing agency; and (4) a
    durable medical equipment supplier.
    6
    subsidiaries with high personnel costs, [such as MHH].”3 App. at 32.
    The Home Office claimed in a letter dated November 15, 1993, that
    there would be a distorted allocation to its durable medical equipment
    subsidiary under the CMS-prescribed default method due to that
    subsidiary’s high cost of goods sold.
    On August 4, 1993, Independence Blue Cross responded by
    letter requesting “additional information,” including a more detailed
    justification for the change. App. at 33-34. Independence Blue Cross
    indicated that it would make a final determination after reviewing the
    additional information and noted that “all methodologies that we
    approve are subject to verification during audit.” 
    Id. at 34.
    In
    response the Home Office provided a more detailed description of its
    proposed alternative allocation method and referred Independence
    Blue Cross to other data it previously had supplied in connection with
    quarterly reports. Specifically, the Home Office explained that it
    believed an allocation of costs to all subsidiaries on a cost-to-total
    cost basis (the CMS-prescribed default method) would result in an
    inappropriately large allocation of Home Office costs to its durable
    medical equipment subsidiary.4 On February 11, 1994, Independence
    Blue Cross approved the request.
    3
    Liberty Health System, later renamed Mercy Home Health
    Services after Mercy Health System acquired Liberty in 1995, sent the
    letter, but we refer to the parent company of MHH, now Mercy Home
    Health Services, as the Home Office and to the provider component as
    MHH.
    4
    Specifically, the letter stated, in part:
    In July of 1993, [the Home Office] purchased a
    [durable medical equipment] company. The
    nature of this business’s expenses are highly
    weighted towards Cost of Goods Sold and
    Depreciation. Under our current cost to cost
    allocation methodology, home office cost would
    be unfairly allocated based on total costs of each
    subsidiary. This would then include [the Cost of
    Goods Sold and Depreciation for the durable
    medical equipment subsidiary,] for which the
    home office provides little support.
    App. at 35.
    7
    The Home Office used this alternative allocation method
    through fiscal year 1996. On June 26, 1996, Independence Blue
    Cross, without elaborating on the basis for its decision, notified the
    Home Office that as of January 1, 1997, it no longer would accept the
    Home Office’s alternative cost allocation method. In response, MHH
    unilaterally implemented a second alternative allocation method,
    effective January 1, 1997, but Independence Blue Cross never
    approved this method.
    In 1997, Independence Blue Cross voluntarily terminated its
    contract as a Medicare fiscal intermediary.5 By notice dated
    September 30, 1998, the successor intermediary reopened and
    adjusted MHH’s and the Home Office’s cost reports for fiscal year
    1995 to substitute the CMS-prescribed default method for the first
    alternative method approved by Independence Blue Cross. This
    adjustment decreased MHH’s allowable costs by $272,000. The
    successor intermediary similarly reopened and adjusted the cost
    reports for fiscal year 1996, reducing Medicare reimbursement by
    $495,868. The successor intermediary also adjusted all costs reports
    for 1997-1999 based on the default method, thereby rejecting MHH’s
    second alternative allocation methodology, which MHH had adopted
    unilaterally.
    C. Procedural History
    1. Decision of the PRRB
    MHH separately appealed to the PRRB from the successor
    intermediary’s adjustments to fiscal years 1995-1996 and 1997-1999.
    After a consolidated hearing, the PRRB reversed the disallowance for
    fiscal years 1995-1996 but affirmed the disallowance arising out of
    MHH’s unapproved use of the second alternative allocation method
    during fiscal years 1997-1999. In reversing the disallowance for
    fiscal years 1995-1996, the PRRB held that MHH’s reliance on the
    intermediary’s written instruction should be protected even if the
    successor intermediary subsequently changes its position.
    5
    Wellmark, Inc. succeeded Independence Blue Cross as the fiscal
    intermediary on August 4, 1997, and Cahaba Government Benefit
    Administrators succeeded Wellmark on June 1, 2000. Because the
    events at issue include actions taken by both Wellmark and Cahaba, we
    will refer to them singularly as the “successor intermediary” to
    Independence Blue Cross.
    8
    2. Decision of the Secretary
    The parties sought review of the PRRB decision by the Acting
    Deputy Administrator (“Administrator”) of the CMS, who granted
    review and partially reversed by reinstating the successor
    intermediary’s adjustments to fiscal years 1995-1996.6 The
    Administrator concluded that the first alternative allocation method
    used in 1995-1996 was similar to and based on the same rationale as
    the second alternative allocation method that the PRRB examined and
    disapproved for use in 1997-1999. Upon a review of the entire
    record, the Administrator determined that MHH “failed to
    demonstrate that the prior approved methodology for allocating
    [1995-1996] home office costs is, in fact, a more accurate and
    sophisticated method.” App. at 29.
    Notably, the Administrator rejected MHH’s reliance argument:
    The Administrator does not agree that the
    methodology for the FYs 1995 and 1996 can be
    allowed only on the basis that it was approved by the
    prior intermediary. This basis for such an allowance
    ignores the dictates of the Medicare program set forth
    in § 1861(v)(1)(A) of the Act and elevates the PRM
    prior approval provisions above the requirements of
    the statute. A general principle under Medicare set
    forth at § 1861(v)(1)(A) of the Act is that to be
    reimbursable, the cost must be related to patient care
    and that Medicare shall not pay for costs incurred by
    non-Medicare beneficiaries, and vice-versa, that is,
    Medicare prohibits cross-subsidization of costs.
    Moreover, the documentation requirements of the
    statute and the regulation places the burden of
    demonstrating that costs are to be paid by Medicare on
    the provider.
    App. at 28-29. The Administrator reiterated that “regardless of the
    prior approval (which is subject to audit),” the successor intermediary
    properly disallowed MHH’s cost allocation methodology because
    MHH “failed to articulate a valid rationale” supporting its
    methodology. App. at 29. Above all, the Administrator stressed that
    6
    The Deputy Administrator signed the Secretary’s final decision,
    but we will refer to the “Administrator” as having made the decision.
    9
    prior approval, or the lack thereof, cannot negate “the Medicare cost
    principle prohibiting cost shifting.” App. at 29.
    3. Decision of the District Court
    MHH sought review of the Secretary’s final decision in the
    district court. The parties filed cross-motions for summary judgment,
    and the district court denied MHH’s motion and granted summary
    judgment in favor of the Secretary. The district court based its
    decision primarily on 42 C.F.R. § 405.1885(b)(1), which follows the
    congressional directive of 42 U.S.C. § 1395x(v)(1)(A) to provide for
    retroactive corrective adjustments of prior costs reports, even after a
    provider has submitted its fiscal and statistical reports. The court
    rejected MHH’s claim that it reasonably relied on the intermediary’s
    prior approval of its cost allocation methodology, and the court
    concluded that the Administrator’s rejection of the alternative
    allocation methodology for fiscal years 1995-1996 was supported by
    substantial evidence. On April 6, 2005, MHH timely filed its notice
    of appeal.
    III.   JURISDICTION AND STANDARDS OF REVIEW
    The district court exercised jurisdiction pursuant to 42 U.S.C.
    § 1395oo(f)(1), and we have jurisdiction under 28 U.S.C. § 1291 over
    MHH’s appeal. We can set aside the Administrator’s decision only if
    it is “unsupported by substantial evidence,” is “arbitrary, capricious,
    an abuse of discretion, or [is] otherwise not in accordance with law.”
    5 U.S.C. § 706(2)(A), (E); see also 42 U.S.C. § 1395oo(f)(1)
    (providing that judicial review of reimbursement decisions shall be
    made under the Administrative Procedures Act, 5 U.S.C. § 706).
    Because we apply the same standard of review as the district court,
    we will proceed de novo with respect to our review of the district
    court disposition. See Mercy Catholic Med. Ctr. v. Thompson, 
    380 F.3d 142
    , 151 (3d Cir. 2004); see also Robert Wood Johnson Univ.
    Hosp. v. Thompson, 
    297 F.3d 273
    , 280 (3d Cir. 2002).
    The decision of the agency is entitled to deference as
    articulated in Chevron U.S.A. v. Natural Resources Defense Council,
    Inc., 
    467 U.S. 837
    , 842-43, 
    104 S. Ct. 2778
    , 2781-82 (1984). See
    Robert Wood Johnson 
    Hosp., 297 F.3d at 281
    . Under Chevron, we
    first must determine if Congress has spoken directly to the question at
    issue, and if Congress’ intent is clear, our inquiry ends as we “must
    10
    give effect to the unambiguously expressed intent of Congress.”
    
    Chevron, 467 U.S. at 843
    , 104 S.Ct. at 2781. If we decide that
    Congress has not spoken directly to the issue and “the statute is silent
    or ambiguous with respect to the specific issue,” we must ask whether
    the agency’s interpretation is based on a “permissible construction of
    the statute.” 
    Id. If we
    find that it is, we afford deference to that
    interpretation. 
    Id. If Congress
    “explicitly left a gap for an agency to
    fill . . . a court may not substitute its own construction of a statutory
    provision for a reasonable interpretation made by the administrator of
    an agency.” 
    Id. at 843-44,
    104 S.Ct. at 2782.
    It is well settled that a court must afford substantial deference
    to an agency’s interpretation of its own regulations. Thomas
    Jefferson Univ. Hosp. v. Shalala, 
    512 U.S. 504
    , 512, 
    114 S. Ct. 2381
    ,
    2386 (1994). This broad deference is particularly appropriate in
    contexts that involve a “complex and highly technical regulatory
    program, such as Medicare, which requires significant expertise and
    entail[s] the exercise of judgment grounded in policy concerns.” 
    Id. (citation and
    internal quotation marks omitted); see also Wisconsin
    Dept. of Health and Family Serv. v. Blumer, 
    534 U.S. 473
    , 497, 
    122 S. Ct. 962
    , 976-77 (2002). Thus, a court does not have the “task . . . to
    decide which among several competing interpretations best serves the
    regulatory purpose.” Thomas Jefferson Univ. 
    Hosp., 512 U.S. at 512
    ,
    114 S.Ct. at 2386. Instead, “the agency’s interpretation must be given
    controlling weight unless it is plainly erroneous or inconsistent with
    the regulation.” 
    Id. IV. DISCUSSION
    MHH asserts that we do not owe deference to the
    Administrator’s decision allowing the successor intermediary to
    reopen cost reports for fiscal years 1995 and 1996 and disallowing the
    alternative cost allocation method approved by the prior intermediary
    because it contradicted the controlling rules and prior administrative
    decisions applying them. In addition, MHH submits that the
    Administrator’s decision was not supported by substantial evidence.
    A. Reopening and Disallowance of Alternative Allocation
    Method
    MHH contends that the Administrator erred in concluding that
    the “dictates of the Medicare program set forth in § 1861(v)(1)(A) of
    11
    the Act,” app. at 28, must be elevated above the PRM prior approval
    provisions. To this end, MHH submits that the Administrator’s
    decision runs afoul of the “plain terms of the agency’s own
    longstanding rules,” and that consequently we owe it no deference.
    See appellant’s br. at 22-27. Specifically, MHH argues that the
    Administrator contravened the plain language of the PRM §
    2150.3(D)(2)(b), a “binding interpretative rule.” See 
    id. at 24-25.
    The “plain language” to which MHH refers is, of course, the
    requirement in PRM § 2150.3(D)(2)(b) that a provider must apply an
    approved alternative allocation method to all subsequent accounting
    periods, “unless the intermediary approves a subsequent change for
    the home office.” Nothing in the Administrator’s decision, however,
    contravenes PRM § 2150.3(D)(2)(b), let alone its plain language.
    There is notably absent from section 2150.3(D)(2)(b) any language
    indicating that the intermediary’s approval binds the Secretary or that
    the approval insulates a provider from the reopening and retroactive
    corrective adjustment provisions designed to prevent cross-
    subsidization. As an analytical matter, it seems entirely possible that
    a provider may be required to implement an approved alternative
    allocation method, yet nonetheless remain subject to reopening and
    audit with an obligation to furnish sufficient, accurate and auditable
    data supporting its alternative method and claims for reimbursement.
    According to MHH, prior approval by an intermediary
    effectively renders the provider’s alternative allocation method
    binding upon all future cost reports and unreviewable until the
    intermediary prospectively approves a change. See, e.g., reply br. at 9
    (invoking a purported “unbroken series of final agency decisions that
    recognize the binding effect of an Intermediary’s prior approval until
    after that approval is withdrawn by the Intermediary”) (first emphasis
    added). But PRM § 2150.3(D)(2)(b) does not exist in a vacuum;
    rather, it is part of the overall Medicare reimbursement scheme, see
    Guernsey Mem’l 
    Hosp., 514 U.S. at 94
    , 115 S.Ct. at 1236, which
    includes the “dictates of the Medicare program set forth in § 1861
    (v)(1)(A) of the Act,” app. at 28, cited by the Administrator. The
    question before us is not whether we believe that the Administrator’s
    decision represents the best interpretation of the Medicare statute and
    regulations but rather whether it is reasonable. See Smiley v.
    Citibank, N.A., 
    517 U.S. 735
    , 744-45, 
    116 S. Ct. 1730
    , 1735 (1996).
    This is particularly so given the scope and complexity of the
    Medicare statute and regulations, see, e.g., 
    Blumer, 534 U.S. at 497
    ,
    122 S.Ct. at 976-77, and the clear congressional directive to the
    Secretary to promulgate regulations to “provide for the making of
    suitable retroactive corrective adjustments,” see 42 U.S.C. §
    12
    1395x(v)(1)(A). Given that the plain language of PRM §
    2150.3(D)(2)(b) does not bind the Secretary, and in light of the clear
    congressional prohibition on cross-subsidization and the regulatory
    machinery in place to achieve compliance with this mandate, we
    conclude that the Administrator’s interpretation is based on a
    permissible construction of the Medicare statute and regulations.
    Furthermore, we reject MHH’s argument that we do not owe
    deference to the Administrator’s decision because the decision
    “suddenly veers from its long established and more contemporaneous
    interpretation.” Appellant’s br. at 26; see also reply br. at 2 (“The
    agency’s prior decisional law is uniformly consistent with MHH’s
    position as well.”). On the contrary, some cases suggest that a
    provider remains on notice of an intermediary’s authority to reopen
    and perform retroactive corrective adjustments notwithstanding the
    intermediary’s prior advice. See, e.g., St. Joseph Med. Ctr. v. Blue
    Cross Blue Shield Ass’n, HCFA Adm’r Dec. No. 94-D76, Medicare
    and Medicaid Guide (CCH) P 42, 957 (Nov. 14, 1994) (“[W]hile the
    Provider may have initially relied on incorrect information conveyed
    by its Intermediary . . . the Provider remained on notice that the
    Intermediary retained the authority to reopen the determinations in the
    event that they reflected payment owed in contravention of the
    governing statutes and regulations[.]”).
    We recognize that the PRRB suggested in its decision in
    Extendicare v. BCBSA in 2000 that a provider ought to be able to rely
    on advice of its fiscal intermediary, but that suggestion is mere dicta
    supported only by a single agency decision that predated the Supreme
    Court’s decision in Office of Personnel Management v. Richmond,
    
    496 U.S. 414
    , 420-22, 
    110 S. Ct. 2465
    , 2469-70 (1990), abjuring
    application of equitable estoppel against the government by a party
    seeking public funds. See Extendicare 1996 Ins. Allocation Group v.
    BCBSA/United Gov’t Serv., PRRB Dec. No. 2000-D88, Medicare &
    Medicaid Guide (CCH) P 80, 573 (Sept. 26, 2000) (citing Chicago
    Lakeside Hosp. v. Aetna Life Ins. Co., PRRB Dec. No. 89-D66,
    Medicare and Medicaid Guide (CCH) P 38, 208 (Sept. 27, 1989),
    aff’d with modifications, HCFA Adm’r Dec., Medicare and Medicaid
    Guide (CCH) P 38, 260 (Nov. 20, 1989)). Our result that the prior
    approval by an intermediary is not binding is consistent with
    Monongahela Valley Hosp., Inc. v. Sullivan, 
    945 F.2d 576
    , 588-89
    (3d Cir. 1991), in which we held that OPM v. Richmond foreclosed a
    Medicare provider’s estoppel claim against the Secretary in asserting
    its claim to additional Medicare reimbursement and that reliance upon
    intermediary approval as “binding” would not have been reasonable
    13
    in light of the reopening provisions.
    Overall, we are satisfied that contrary to MHH’s claim, the
    agency’s prior decisions hardly constitute “an unbroken series” of
    final decisions “uniformly consistent with MHH’s position.” Reply
    br. at 2. If anything, the prior decisions can be characterized as
    elevating Medicare cost principles above the prior approval
    provisions found in the PRM. As noted by the Administrator, it is
    significant that prior agency decisions have held that “the lack of
    prior approval is secondary to the Medicare cost principle prohibiting
    cost shifting and [to] the accurate payment of costs.” See app. at 29
    (citing Sunbelt Health Care Ctrs. Group Appeal v. Aetna Life Ins.
    Co., PRRB Dec. No. 97-D13, Medicare and Medicaid Guide (CCH) P
    44, 923, (Dec. 3, 1996)). It was reasonable for the Administrator to
    conclude that, just as Medicare cost principles take priority over the
    absence of prior approval, so, too, do the same cost principles take
    priority over the presence of prior approval. App. at 29 (“[T]he
    existence of prior approval in this case does not negate those same
    Medicare principles and permit the payment of costs not otherwise
    allowable.”).
    B. Substantial Evidence
    1. Burden of Producing Adequate Cost Data
    As a threshold matter on the substantial evidence issue, the
    parties disagree about allocating the burden of proof, an inquiry
    separate from, albeit related to, the sufficiency of the evidence. MHH
    argues that it was “saddled with the affirmative burden of reproving
    the accuracy of [the first alternative allocation] method based on data
    that it was not required to have.” Appellant’s br. at 38-39. MHH
    claims the Administrator thus contravened “the broader principle that
    an agency bears the affirmative burden of justifying a change from a
    position previously taken.” Appellant’s br. at 38 (citing Motor Veh.
    Mfrs. Ass’n v. State Farm Mut. Ins. Co., 
    463 U.S. 29
    , 46-47, 
    103 S. Ct. 2856
    , 2868-69 (1983); Atchison, Topeka & Santa Fe R.R. v.
    Wichita Bd. of Trade, 
    412 U.S. 800
    , 808, 
    93 S. Ct. 2367
    , 2375
    (1973)). The cases cited by MHH stand for the principle that an
    agency must justify a departure from past practice that results in
    reversal of agency policy. See Motor Veh. Mfrs. 
    Ass’n, 463 U.S. at 41-42
    , 103 S.Ct. at 2865-66; 
    Atchison, 412 U.S. at 807-808
    , 93 S.Ct.
    at 2375-76. As explained above, however, here there was no such
    reversal in agency policy.
    14
    Furthermore, contrary to MHH’s contention, none of the cases
    it cites establish a rule whereby the approval of an intermediary shifts
    the burden of proof on the sufficiency of the evidence to the
    Secretary. Rather, in both of the cases cited, the PRRB based its
    decisions, in part, on findings that the providers proffered adequate
    costs data capable of verification. See VNA of Dallas v. BC/BS
    Group Hosp. Servs., Inc., PRRB Dec. No. 87-D100, Medicare and
    Medicaid Guide (CCH) P 36, 647 (Sept. 3, 1987) (“Rarely has the
    Board seen either the extent or the quality of documentary evidence
    as that presented by the provider in this case to support the Board’s
    conclusion [that the provider’s time studies were auditable].”)
    (emphasis added), aff’d, HCFA Adm’r Dec., Medicare and Medicaid
    Guide (CCH) P 36, 751 (Nov. 4, 1987); Rhode Island Hosp. v. Blue
    Cross and Blue Shield Ass’n, HCFA Adm’r Dec., Medicare and
    Medicaid Guide (CCH) P 34, 968 (Aug. 26, 1985) (“The Board
    reviewed the evidence presented in this case, and found that the
    records and statistical data maintained and furnished by the provider
    were sufficient to support [its cost method].”) (emphasis added).
    The governing statutes and regulations indicate that the
    burden of proof remains on the provider. The PRM provision upon
    which MHH primarily relies places the burden upon providers to
    make a “written request with its justification to the intermediary”
    when seeking to utilize an alternative allocation method. See PRM §
    2150.3(D)(2)(b). With regard to reimbursement generally, the statute
    itself prohibits payment “unless [the provider] has furnished such
    information as the Secretary may request in order to determine the
    amounts due such provider” for the particular cost period at issue. 42
    U.S.C. § 1395g(a). Similarly, the Secretary’s implementing
    regulation requires that “[p]roviders receiving payment on the basis of
    reimbursable cost must provide adequate cost data.” 42 C.F.R. §
    413.24(a). As noted above, the data must be “capable of being
    audited,” and be “accurate and in sufficient detail to accomplish the
    purposes for which it is intended.” 42 C.F.R. § 413.24(c).
    Accordingly, the Administrator did not err in requiring MHH to
    produce adequate cost data to support its alternative allocation
    method and claim for reimbursement.
    2. Sufficiency of Evidence
    Substantial evidence is “more than a mere scintilla. It means
    such relevant evidence as a reasonable mind might accept as adequate
    to support a conclusion.” Richardson v. Perales, 
    402 U.S. 389
    , 401,
    
    91 S. Ct. 1420
    , 1427 (1971) (quoting Consol. Edison Co. v. NLRB,
    15
    
    305 U.S. 197
    , 229, 
    59 S. Ct. 206
    , 217 (1938)). In our review, we do
    not consider the case de novo with respect to the Administrator,
    resolve conflicts in the evidence, or decide questions of credibility.
    Myers v. Sec’y of Health & Human Servs., 
    893 F.2d 840
    , 842 (6th
    Cir. 1990).
    MHH asserts that the Administrator’s decision was not
    supported by substantial evidence. In particular, MHH argues that
    “[m]ost significantly, [the Administrator] rendered no independent
    findings relating to the allocations in FY ‘95 & ‘96, but relied entirely
    on the PRRB’s findings relating to FY ‘97-‘99[,]” thereby rejecting
    the first alternative allocation method (1995-1996) based on findings
    related to the second alternative allocation method (1997-1999).
    Reply br. at 22-23. We acknowledge that this argument appears
    persuasive on its face, but it is critical to understand that it is
    premised on the first alternative allocation method at issue being
    materially different from the second alternative method, the rejection
    of which MHH does not challenge. That premise, however, is belied
    by the Administrator’s stated justifications:
    With respect to FYs 1997 through 1999, the
    Administrator agrees with the Board’s determination
    that the Intermediary’s adjustments to the Provider’s
    home office cost statements were proper. As the
    Provider set forth, its rationale for the methodology used for the FYs
    1995 and 1996 period is also its rationale for the FYs 1997 through
    1999 period methodology. The record shows that the Provider failed
    to collect data or provide any specific computations or reasonable
    justification to support their contention that the alternative method in
    fact resulted in more equitable and accurate allocation of costs. The
    record also shows, as the Board agreed, that the Provider did not offer
    a valid rationale for excluding the cost of goods sold from the CMS-
    prescribed allocation method.
    App. at 29-30 (footnotes omitted) (emphasis added).
    Thus, the Administrator explained the reason for rejecting the
    first alternative allocation method based on findings related to the
    second alternative method: the two methodologies were “very
    similar,” in that “[t]he Provider sets forth [the] same unsupportable
    rationale for the very similar methodology used for FYs 1995 through
    1999.” App. at 30 n.7. This finding that the two allocation methods
    were based on the same rationale is bolstered by MHH’s own
    consolidated post-hearing brief, see app. at 29 n.6, in which MHH
    16
    explained that its rationale for excluding certain cost of goods sold
    was “equally applicable” to both methodologies. See provider’s
    consol. post-hr’g br. at 17, n.9.
    Notably, the PRRB rejected the “equally applicable” rationale
    as applied to the 1997-1999 methodology:
    The Board is persuaded by the Intermediary’s
    argument that the cost of labor in the service-oriented
    affiliates could just as well be equated to the ‘cost of
    goods sold’ in the [durable medical equipment]
    affiliate. Thus, there is no valid rationale for excluding
    the cost of goods sold from the CMS-prescribed
    allocation methodology.
    App. at 20. Accordingly, on this record substantial evidence
    supports the Administrator’s decision that the flawed, rejected
    rationale underlying the 1997-1999 methodology was “equally
    applicable” to the 1995-1996 methodology, thus warranting rejection
    of the 1995-1996 methodology.
    V.    CONCLUSION
    For the foregoing reasons, we will affirm the order of the
    district court entered March 18, 2005.
