This case concerns what recourse is available to a provider hospital that, although eligible to receive Medicare reimbursement for certain expenses, mistakenly fails to ask for that reimbursement in a timely manner. The Secretary of Health and Human Services reimburses hospitals and other organizations for services they provide to beneficiaries of the Medicare program, 42 U.S’.C. § 1395 et seq. After the end of each fiscal year, a hospital must submit a cost report to a “fiscal intermediary,” a private firm that processes claims for the Secretary. The intermediary reviews the cost report and issues a Notice of Provider Reimbursement (NPR), which indicates the reimbursement to which the provider is entitled. If a provider is dissatisfied with an NPR, it can appeal to the Provider Reimbursement Review Board (the Board). See 42 U.S.C. § 1395oo(a).
In its cost reports for 1993 and 1994, Kennebec Valley Medical Center (Kenne-bec), a hospital in Augusta, Maine, listed zero as its claim for bad debts reimbursable by Medicare. Reimbursable bad debts are uncollectible debts resulting from the failure of Medicare beneficiaries to pay deductible or coinsurance amounts. See 42 C.F.R. § 413.80(d). Mid-Maine Medical Center (Mid-Maine), a hospital in Wa-terville, Maine, similarly listed zero for reimbursable bad debts in its 1994 cost report. After the intermediary, Blue *495Cross and Blue Shield of Maine, issued NPRs for these three cost reports in July and September 1996, both Kennebec and Mid-Maine appealed to the Board. In their appeals, Kennebec and Mid-Maine raised several objections to the NPRs, including claims that they were entitled to reimbursement for Medicare-related bad debts despite having listed zero for them in their cost reports. Kennebec and Mid-Maine asserted that the claims for zero reimbursement were mistakes that they had discovered only after the NPRs had been issued.
The Board dismissed the bad debts issue from all three appeals for lack of statutory jurisdiction. The Board noted that Kenne-bec and Mid-Maine had not included the bad debts in the cost reports they had submitted to the intermediary. Therefore, the Board reasoned, the debts were not “matter[s] covered by [a] cost report as required by 42 U.S.C. § 1395oo(a), and the Board does not have jurisdiction.” Because the Secretary declined to review the Board’s decision, it became a final decision of the agency. See 42 U.S.C. § 1395oo(f)(l).
I
While their appeals were pending before the Board, Kennebec and Mid-Maine merged to form MaineGeneral Medical Center (MaineGeneral). After the Board dismissed the bad debts issue from the appeals, MaineGeneral filed three suits in the United States District Court for the District of Maine. The court consolidated the cases on August 12,1998.
Both MaineGeneral and the Secretary filed motions for summary judgment. On October 15, 1998, the Magistrate Judge issued a Recommended Decision advising that the Secretary’s motion be granted. The Magistrate Judge based his recommendation on his interpretation of 42 U.S.C. § 1395oo(a). That section sets out three prerequisites for an appeal to the Board: 1) the Medicare provider must be “dissatisfied with a final determination of ... its fiscal intermediary ... as to the amount of total program reimbursement due the provider”; 2) the amount in controversy must be $10,000 or more; and 3) the provider must appeal within 180 days of the intetmediary’s final determination. 42 U.S.C. § 1395oo(a). There was no dispute that MaineGeneral had satisfied the second and third requirements. The Magistrate Judge determined that Maine-General had failed to fulfill the first requirement, dissatisfaction with a final determination of the fiscal intermediary.
The Magistrate Judge’s decision relied on dictum in Bethesda Hospital Ass’n v. Bowen, 485 U.S. 399, 108 S.Ct. 1255, 99 L.Ed.2d 460 (1988). In Bethesda, the hospitals had deliberately omitted certain costs from their cost reports, knowing that they could not claim them under the existing regulations (and that the intermediary had no authority to change the regulations). See id. at 401,108 S.Ct. 1255. The hospitals later sought to challenge the regulations and claim the costs in a hearing before the Board. See id. The Secretary contended that the Board lacked jurisdiction over the claims because the hospitals could not be “dissatisfied” as required by § 1395oo(a) if the intermediary had simply awarded the amounts the hospitals had requested.in their cost reports. See id. at 404, 108 S.Ct. 1255. The Supreme Court concluded, however, that the hospitals “could claim dissatisfaction, within the meaning of the statute, without incorporating their challenge in the cost reports filed with their fiscal intermediaries.” Id. at 405, 108 S.Ct. 1255.
In discussing its holding, the Court observed:
[Pjetitioners stand on different ground than do providers who bypass a clearly prescribed exhaustion requirement or who fail to request from the intermediary reimbursement for all costs to which they are entitled under applicable rules. While such defaults might well establish that a provider was satisfied with the amounts requested in its cost report and awarded by the fiscal intermediary, *496those circumstances are not presented here.
Id. at 404-05, 108 S.Ct. 1255. The Magistrate Judge, agreeing with the Seventh Circuit that the above language “strongly suggests that a hospital that does not ask its intermediary to reimburse it for all of the costs for which it is entitled to be reimbursed cannot, on appeal to the Board, first ask for new costs,” Little Co. of Mary Hosp. & Health Care Ctrs. v. Shalala, 24 F.3d 984, 993 (7th Cir.1994), found that MaineGeneral’s claim of zero for bad debts on its cost reports meant that it could not be “dissatisfied” with the intermediary’s determination of the bad debts issue. Because MaineGeneral was not “dissatisfied,” it failed to meet the first requirement of Board jurisdiction under § 139500(a).1 The district court issued an order adopting the Magistrate Judge’s recommendation and entered judgment in favor of the Secretary on December 9, 1998. This appeal followed.
II
Under the Medicare program, fiscal intermediaries make estimated payments to hospitals and other service providers throughout the year based on each institution’s projected costs. See 42 U.S.C. § 1395g(a); 42 C.F.R. § 413.60(a), (c). Providers are required to submit a cost report after the end of each fiscal year.2 See 42 U.S.C. § 1395g(a); 42 C.F.R. § 413.20(b). A cost report is a lengthy, complex document, sometimes three-quarters of an inch thick when completed. See Athens Community Hosp., Inc. v. Schweiker, 743 F.2d 1, 3 (D.C.Cir.1984).
The intermediary reviews the cost report and requests further information from the provider as necessary. See 42 C.F.R. § 413.20(d)(2). A provider may file an amended cost report to correct material errors discovered after the filing of the original cost report. See Health Care Fin. Admin., Provider Reimbursement Manual, Part I § 2931.2(A) (1999). A provider may appeal to the Board an intermediary’s refusal to accept an amended cost report that was submitted before the NPR was issued. See id. § 2926 app. A, ¶ B.3.
When the review of the cost report is complete, the intermediary issues an NPR, which indicates the total reimbursement for the year covered by the cost report and explains any adjustments the intermediary has made to costs claimed by the provider. See 42 C.F.R. § 405.1803. If the total reimbursement is higher than the estimated payments already made to the provider, the Secretary pays the deficiency; otherwise, the provider refunds any overpayment to the Secretary. See 42 C.F.R. §§ 405.1803(c), 413.60(c).
If a provider mistakenly omits something from its cost report and discovers the mistake after the NPR has been issued, it is not left without recourse. For up to three years after the intermediary has issued an NPR, a provider can request that the intermediary reopen and revise its determination. See 42 C.F.R. § 405.1885(a). Whether to grant this request to reopen is a matter for the intermediary’s sole discretion; it is subject to neither administrative nor judicial review. See Your Home Visiting Nurse Servs., Inc. v. Shalala, 525 U.S. 449, 451-56, 119 S.Ct. 930, 933-34, 142 L.Ed.2d 919 (1999). MaineGeneral did not request that the in-*497termediary reopen its NPRs; instead, it appealed to the Board.

In St Luke’s Hospital v. Secretary of Health and Human Services, 810 F.2d 325 (1st Cir.1987), this court addressed the question of whether the Board has the power to decide an issue that was not first raised before the intermediary. See id. at 326. We held that it does, and that the power is discretionary. See id. at 330, 332. We are bound by the St. Luke’s decision if it is on point, unless it has been subsequently overruled or other exceptional circumstances apply. See Williams v. Ashland Eng’g Co., 45 F.3d 588, 592 (1st Cir.1995). We think that St. Luke’s is on point and remains good law. We hold, therefore, in accordance with St. Luke’s, that the Board has statutory jurisdiction to hear MaineGeneral’s claim, but that it is not required to hear it.
St. Luke’s involved a dispute between a hospital and an intermediary over whether certain sick leave expenses were reimbursable. See 810 F.2d at 327. After St. Luke’s included the expenses in its 1978 cost report and the intermediary denied reimbursement, St. Luke’s “self-disallowed” its 1979 sick leave expenses on its 1979 cost report. See id. “Self-disallowed” costs are entered on a worksheet in the cost report, but the provider does not request reimbursement for them, and they are generally not considered by the intermediary. See St. Luke’s Hosp. v. Secretary of HHS, 632 F.Supp. 1387, 1391 (D.Mass.1986). When St. Luke’s appealed its 1979 reimbursement to the Board, the Board “evidently took the position ... that it did not have jurisdiction to consider a self-disallowed cost, there being no ‘dispute’ between the fiscal intermediary and the provider.” Id. The district court, analyzing § 1395oo(d) — which it termed “[t]he statutory section governing the jurisdiction of the Board” — held that the Board had jurisdiction to hear the appeal of the self-disallowed costs. Id. at 1392-94. The Secretary appealed this determination, and this court held that the Board had the legal power to decide matters not raised below. See St. Luke’s, 810 F.2d at 330.
In this circuit, panels “are, for the most part, bound by prior panel decisions closely on point.” Williams, 45 F.3d at 592. There are two exceptions to this rule. The first is that “[a]n existing panel decision may be undermined by controlling authority, subsequently announced, such as an opinion of the Supreme Court, an en banc opinion of the circuit court, or a statutory overruling.” Id. The second exception covers “those relatively rare instances in which authority that postdates the original decision, although not directly controlling, nevertheless offers a sound reason for believing that the former panel, in light of fresh developments, would change its collective mind.” Id.
First, we must determine whether St. Luke’s is closely on point. The Magistrate Judge’s opinion in this case, which was adopted by the district court, distinguished St. Luke’s on the ground that in St. Luke’s, the hospital’s failure to ask for reimbursement of certain expenses in its cost report was intentional rather than inadvertent. Nothing in the St. Luke’s opinion suggests that such a distinction played a significant role in the court’s interpretation of the Board’s statutory jurisdiction. See 810 F.2d at 327-29. Indeed, the only point at which the St. Luke’s court attaches any weight to the fact that the hospital self-disallowed the costs at issue is at the very end of the opinion, in its discussion of whether the Board should be required to hear the hospital’s claim. See id. at 332 (observing that St. Luke’s has “a strong equitable argument” based on self-disallowance, but holding nonetheless that the Board has discretion over whether it will hear an appeal).
Furthermore, the St. Luke’s opinion does not distinguish cases involving inadvertently omitted costs. The St. Luke’s court phrased its holding this way:
The question before us is whether this statute grants the Board the power to order reimbursement for costs identified *498in the cost report, but as to which the hospital did not specifically ask the intermediary for reimbursement. Put more broadly, the question is whether the statute gives the Board the power to decide a new issue raised for the first time before it. We believe that the statute does give the Board this power. We also believe, however, that the Board need not exercise that power. Because the District of Columbia Circuit has taken a contrary view of the matter, Athens Community Hospital v. Schweiker, 743 F.2d 1 (D.C.Cir.1984) (Athens II) ..., we shall explain our reasoning in some detail.
Id. at 326 (some citations omitted). In Athens II, the D.C. Circuit held that the Board had no jurisdiction over costs for which a provider inadvertently failed to request reimbursement. See 743 F.2d at 10 & n. 17. If the distinction between “self-disallowed” costs and “mistakenly omitted” costs had been significant, the St. Luke’s court could have simply distinguished Athens II on that basis. Instead, the court spent two pages explaining why it was unconvinced by the reasoning of Athens II. See St. Luke’s, 810 F.2d at 329-30. In light of this, we regard the holding of St. Luke’s as applicable to “matters not raised” before the intermediary, id. at 330, whether the failure to raise the matter was deliberate or inadvertent.3
A second possible ground for distinguishing St. Luke’s here would be that St. Luke’s concerned only subsection § 1395oo(d), while this case (like Bethesda ) turns on the interpretation of § 1395oo(a).4 We believe that an examination of St. Luke’s and Bethesda refutes this argument. First, the holding of St. Luke’s is that “the Board has the legal power to decide matters not raised below.” See 810 F.2d at 330. This holding is not a narrow one based on a parsing of § 1395oo(d) alone: it relies on legislative history, see id. at 328; the nature of judicial and administrative appellate bodies, see id. at 328-29; other subsections of § 1395oo, see id. at 329 (§ 1395oo(f)); and the special features of Board review, see id. To confine St. Luke’s to § 1395oo(d) alone would be to ignore its language and the analytic rationale for its conclusion about the Board’s jurisdiction.
Furthermore, Bethesda makes nothing of the possible distinction between “subsection (a)” and “subsection (d)” cases. Bethesda, which could be characterized as a subsection (a) case, states that it is “re-solv[ing] a conflict among the Courts of Appeals,” and lists eight circuit opinions, the majority of which could be classified as subsection (d) cases. See 485 U.S. at 402-OS & n. 1, 108 S.Ct. 1255; St. Luke’s, 810 F.2d at 327 (noting the Secretary’s argument that “ § 1395oo(d) denies the Board the power to decide any issues not first raised before the intermediary”); North Broward Hosp. Dist. v. Bowen, 808 F.2d 1405, 1409 (11th Cir.1987) (defining “the scope of jurisdiction conferred by § 1395oo(d)”); Community Hosp. v. HHS, 770 F.2d 1257, 1262 (4th Cir.1985) (same); Athens II, 743 F.2d at 3 (“The [Board’s] jurisdiction- — the crux of the dispute here — -is set out in section 1395oo(d)....”); Saint Mary of Nazareth Hosp. Ctr. v. Department of HHS, 698 F.2d 1337, 1346 (7th Cir.1983) (rejecting the Secretary’s § 1395oo(d) jurisdictional argument); see also Tallahassee Memorial Regional Medical Center v. Bowen, 815 F.2d 1435, 1458-59 (11th Cir.1987) (finding subsection (f) more relevant, even though the district courts and parties focused on subsection (d)). If the possible distinction between subsection (a) and subsection' (d) cases mattered to the Bethesda Court, it would not have announced that it was resolving a circuit split involving subsection (d) cases in an opinion focused on subsection (a).
*499A much more plausible interpretation of Bethesda and the court of appeals cases that it cites (including the St. Luke’s opinion) is that they actually deal with the question of the Board’s jurisdiction under § 1395oo as a whole. For example, the Bethesda Court found its understanding of the express language of subsection (a) “supported by the language and design of the statute as a whole,” 485 U.S. at 405, 108 S.Ct. 1255, especially subsection (d), id. at 405-07, 108 S.Ct. 1255. Athens II read subsection (d) in light of the overall statutory scheme, particularly subsection (a). See 743 F.2d at 6; see also Adams House Health Care v. Heckler, 817 F.2d 587, 591 (9th Cir.1987) (“The D.C. Circuit [in Athens II ] correctly held that subsections (a) and (d) must be read together.”). And St. Luke’s confirmed its interpretation of the Board’s powers under subsection (d) by referring to subsection (f). See 810 F.2d at 329.
The interrelationship between the subsections of § 1395oo can also be seen in the original reasoning the Board offered for its dismissal of the bad debts issues here. In its letters informing Kennebec and Mid-Maine of its dismissal of the bad debts issues from their appeals, the Board stated that it lacked jurisdiction over the debts because they were not “matter[s] covered by [a] cost report as required by 42 U.S.C. § 1395oo(a).” The only reference to “matters covered by [a] cost report” in § 1395oo, however, is in subsection (d), not (a). 42 U.S.C. § 1395oo(a), (d).
In Bethesda, the Supreme Court defined a matter “covered by [a] cost report” as “a cost or expense that was incurred within the period for which the cost report was filed,'even if such cost or expense was not expressly claimed.” 485 U.S. at 406, 108 S.Ct. 1255 (internal quotation marks omitted). Under this definition, the bad debts were clearly a matter covered by a cost report, contrary to the Board’s assertion.
Having concluded that St. Luke’s is on point, we still must consider whether the exceptions to stare decisis detailed in Williams apply. The first exception is not applicable here. The Supreme Court’s suggestion in Bethesda that a provider’s failure to request reimbursement from the intermediary for all costs to which it was entitled “might well establish that a provider was satisfied with the amounts requested in its cost report and awarded by the fiscal intermediary,” 485 U.S. at 405, 108 S.Ct. 1255, is explicitly dictum — '“those circumstances are not presented here,” id. Nor has St. Luke’s been subsequently overruled by statute or First Circuit en banc opinion. The second “relatively rare” exception to stare decisis would apply if we believed that subsequent non-controlling authority — specifically the Bethesda dictum — would have altered the holding of St. Luke’s. We do not think that is the case. As noted above, the St. Luke’s holding rested on a number of grounds: the plain language of the statute, its legislative history, the nature of appellate bodies in general, and the specific features of Board review. See 810 F.2d at 327-29.
As the St. Luke’s court noted, § 1395oo(d) specifically states that the Board has the power “to make ... other revisions on matters covered by [the] cost report ... even though such matters were not considered by the intermediary.... ” Id. at 327 (quoting § 1395oo(d)) (alteration and omissions in original) (internal quotation marks omitted). The St. Luke’s court held that § 1395oo(d) is not ambiguous, and therefore no deference is due the Secretary’s view of the statute under Chevron. See id. at 331 (citing Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 842-43, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984)). The St. Luke’s court also found confirmation of its reading in the statute’s legislative history, which, inter alia, describes the provision in question as permitting the Board to make “revisions involving matters not considered by the intermediary.” Id. at 328 (quoting H.R.Rep. No. 92-231, reprinted in 1972 U.S.C.C.A.N. 4989, 5309).
*500The practices of both judicial and administrative appellate bodies provide further support. Even courts or agency-bodies with purely appellate functions have, as a rule, the power to review matters not raised below, though they may choose to exercise such power sparingly. See id. (citing cases); see also_ Singleton v. Wulff, 428 U.S. 106, 121, 96 S.Ct. 2868, 49 L.Ed.2d 826 (1976) (“The matter of what questions may be taken up and resolved for the first time on appeal is one left primarily to the discretion of the courts of appeals....”); Portela-Gonzalez v. Secretary of the Navy, 109 F.3d 74, 77 (1st Cir.1997) (discussing the rule of exhaustion of administrative remedies and its exceptions); United States v. Mercedes-Amparo, 980 F.2d 17, 18 (1st Cir.1992) (“An appellate court ... has the discretionary power, in an exceptional case, to resolve an issue not passed on below.”) The special features of Board review here suggest that its reviewing powers are even broader than those of the typical reviewing body. See St. Luke’s, 810 F.2d at 329. “[T]he Board’s procedure is a kind of ‘hybrid,’ exhibiting some features of initial factfinding (witnesses, cross-examination, new evidence) and some features of review.” Id. at 328.
Finally, we do not believe that the Bethesda opinion, taken as a whole, undermines the holding of St. Luke’s. The Secretary’s position that § 1395oo(a) incorporates an unwaivable and unyielding exhaustion requirement is essentially the same reading that the Court rejected in Bethesda as a “strained interpretation ... inconsistent with the express language of the statute.” 485 U.S. at 404, 108 S.Ct. 1255. The Bethesda court also described the requirement in § 1395oo(d) that a matter have been “covered by such cost report” as the “only limitation” on the Board’s power to review matters not contested before the intermediary, and defined a matter “covered by such cost report” as “a cost or expense that was incurred within the period for which the cost report was filed, even if such cost or expense was not expressly claimed.” Id. at 406, 108 S.Ct. 1255.
Although the dictum cited in the Magistrate Judge’s opinion suggests that providers who mistakenly omit claims from their cost reports may not be able to claim dissatisfaction under § 1395oo(a)(l)(A)(i), we cannot say that the Bethesda opinion in its entirety would have altered the holding of St. Luke’s. Notably, the Bethesda dictum that we have quoted above (to the effect that a failure to request reimbursement “might well establish that a provider was satisfied with the amounts ... awarded by the fiscal intermediary,” 485 U.S. at 405, 108 S.Ct. 1255) could easily be taken to mean that this would be a reasonable factual inference in many cases; the opinion does not say expressly that this inference would be a binding rule of law. We therefore reiterate the holding of St. Luke’s: the Board has statutory jurisdiction to hear claims not first raised before the intermediary, but it may decline to do so as a matter of discretion.
IV
The dissent by our respected colleague makes reasoned and reasonable arguments, but we view the issues differently and respond briefly. The dissent says that this case is different than St. Luke’s because here the hospital did not list the items in its cost report and that is the key fact. A cost report includes both reim-burseable and non-reimburseable costs. See St. Luke’s, 810 F.2d at 326. That a cost is listed in a cost report says nothing about whether the provider is “dissatisfied” with the later decision by the intermediary to reimburse or not reimburse costs. That is established by Bethesda, 485 U.S. at 404, 108 S.Ct. at 1258-59. In fact, the intermediary does not usually even consider matters on the cost report for which no reimbursement is sought. See St. Luke’s, 632 F.Supp. at 1391. The key question is whether the hospital sought reimbursement for the cost. In St. Luke’s, the hospital did not, and this court held that fact did not mean the Board lacked statutory jurisdiction. See St. *501Luke’s, 810 F.2d at 327, 331-32. Contrary to the implications of the dissent’s position, nothing in St. Luke’s suggests that the hospital would not have been “dissatisfied” if it omitted to list the cost on a worksheet in the cost report (whether through inadvertence, or in reliance on the agency’s earlier determination that the costs were not recoverable). In fact, St. Luke’s expressly disagreed with Athens II, a case in which the provider had apparently inadvertently failed to list certain stock option costs in its cost report, and the D.C. Circuit had concluded there was no Board jurisdiction. See id. at 329-30; Athens II, 743 F.2d at 10 & n. 17. Under St. Luke’s, the statutory word “dissatisfied” is not limited to situations in which reimbursement was sought by the hospital from the intermediary.
St. Luke’s also found Chevron abdication to the views of the agency inappropriate on the matter, and we are so bound. See St. Luke’s, 810 F.2d at 331-32. We also note that the Board itself in this case did not clearly distinguish between its powers under § 1395oo(a) and (d), as the dissent attempts to do, either in its handling of this matter, or in its briefs. As we have said, the very decision of the Board under review conflates the two sections, and so is at best an inconsistent statement of agency position, entitled to less deference. See INS v. Cardoza-Fonseca, 480 U.S. 421, 446-48 & n. 30, 107 S.Ct. 1207, 94 L.Ed.2d 434 (1987); Goncalves v. Reno, 144 F.3d 110, 127 (1st Cir.1998).
Finally, we agree with the dissent that it would be entirely permissible for the Board to conclude, as a matter of policy, not to hear this claim. On remand, the Board may well reach this outcome. All we hold is that Congress did not, in the statute, require the Board to reach this result by stripping it of jurisdiction. This outcome preserves some flexibility for the agency, which may be exactly what Congress intended. It is not our job to exercise that flexibility for the agency.
V
Courts are generally not permitted to affirm agency action on grounds implicating the agency’s policy judgments or discretion other than those advanced by the agency whose actions are under review. See SEC v. Chenery Corp., 318 U.S. 80, 88, 63 S.Ct. 454, 87 L.Ed. 626 (1943). There is an exception to this rule where it is clear what an agency’s decision must be, see Thornburgh v. American College of Obstetricians & Gynecologists, 476 U.S. 747, 756 n. 7, 106 S.Ct. 2169, 90 L.Ed.2d 779 (1986), but that exception does not apply here.
The Board decided that it would not hear MaineGeneral’s bad debts claims because it believed it lacked statutory jurisdiction over them. In essence the Board held it could not hear the claims even if it wanted to because § 1395oo precluded jurisdiction. This reasoning was incorrect. The Board must now decide again whether it will hear these claims mistakenly omitted from MaineGeneral’s cost reports, but as a matter of discretion, not statutory jurisdiction. Congress specifically granted the Board “full power and authority” to make rules “necessary or appropriate” to carry out its statutory tasks. 42 U.S.C. § 1395oo(e). As the St. Luke’s court noted, this gives the Board “the power to limit by rule the extent to which it will hear an issue not raised [before the intermediary]; it can also do so on a case-by-case basis.” 810 F.2d at 332.
The choice is up to the Board. It can adopt a policy of hearing such claims or of refusing to hear them, or it can opt to decide on a case-by-case basis. In light of the statutory scheme here, a rule of consistently refusing to hear inadvertently omitted claims would be rational, given the ability of providers to request the intermediary to reopen an NPR up to three years after it has been issued.5
*502“AH we ask of the Board is to give clear indication that it has exercised the discretion with which Congress has empowered it.” St. Luke’s, 810 F.2d at 338 (quoting Chenery, 318 U.S. at 94-95, 63 S.Ct. 454) (internal quotation marks omitted). The decision of the district court is vacated and the case remanded to the Provider Reimbursement Review Board for further proceedings consistent with this opinion.
. The Magistrate Judge held alternatively that even if one agreed with MaineGeneral's contention that the Board had jurisdiction over the bad debts claims, the Board's decision to review the claims is clearly discretionary under § 1395oo(d), and it was well within its authority to refuse to hear the claims.
. When Kennebec and Mid-Maine filed their cost reports, Medicare regulations required hospitals to submit their reports within three months of the end of the fiscal year. See Redesignation of Reasonable Cost Regulations, 51 Fed.Reg. 34,790, 34,800 (1986). An intermediary could grant a one-month extension for good cause, providing the Health Care Financing Administration approved. See id. In 1995, the three-month period was extended to five months, and the granting of extensions was sharply curtailed. See Date for Filing Medicare Cost Reports, 60 Fed.Reg. 33,137, 33,138 (1995).
. We note that the Ninth Circuit has interpreted the holding of St. Luke’s the same way. See Adams House Health Care v. Bowen, 862 F.2d 1371, 1375 n. 3 (9th Cir.1988).
. Neither the Magistrate Judge's opinion nor the Secretary’s brief in this case attempted to distinguish St. Luke's on this ground.
.
