Rehabilitation Association of Virginia, Inc. (the Association) brought this suit against Bruce Kozlowski, director of Virginia’s Department of Medical Assistance Services (Virginia), and Donna Shalala, Secretary of the United States Department of Health and Human Services (DHHS or the Secretary) challenging the legality of certain aspects of Virginia’s Medicaid plan and seeking prospective injunctive relief. On cross-motions for summary judgment, the district court entered judgment in favor of the Association, and Virginia and DHHS now appeal. 838 F.Supp. 243. For the reasons set forth below, we affirm.
I.
Briefly stated, Medicare, Title XVIII of the Social Security Act, 42 U.S.C. §§ 1395-1395cce, is a federally-run program, enacted in 1965, to provide financing for medical procedures for certain disabled individuals and people 65 years of age. 42 U.S.C. §§ 426(a), 1895c. Medicare has two parts, Part A and Part B. Part A, 42 U.S.C. §§ 1395c to 1395i-4, provides reimbursement for inpatient hospital care and related post-hospital, home health and hospice care. 42 U.S.C. § 1395d. Enrollment in Part A is essentially automatic. Part A includes limited cost-sharing provisions in the form of annual deductibles for inpatient hospital service and payments by enrolled individuals of an amount of “coinsurance” that depends on the length of hospital stay. 42 U.S.C. § 1895e. In addition, some individuals who do not directly meet the basic criteria for enrollment may enroll and are required to pay premiums. 42 U.S.C. §§ 1395Í-2, 1395i-2a.
Medicare Part B, 42 U.S.C. §§ 1395j to 1395w-4, is a supplemental voluntary insurance program. Under Part B, individuals entitled to Part A benefits and certain others, see 42 U.S.C. § 1395o, may purchase supplementary insurance for hospital out-patient services, physician services, and other medical services not covered under Part A. 42 U.S.C. § 1395k. Part B also includes a series of cost-sharing provisions. Enrollees must pay a monthly premium and an annual deductible, currently $100. 42 U.S.C. §§ 1395Í (b), 1395r. (There is an exemption from the application of the annual deductible for certain services, see 42 U.S.C. § 1395Í (b)). As to payments of charges after the deductible is exhausted (or where it does not apply), the federal government will pay 80% of the “reasonable charge” for the services. 42 U.S.C. § 1395Í (a). The amount that constitutes a reasonable charge is set annually by the Secretary. 42 U.S.C. § 1395w-4. The service provider can charge the beneficiary for the remaining 20% of the reasonable charge. Id. This charge is usually referred to as a copayment or coinsurance. If the physician is a participating physician, *1447he “takes assignment” in Medicare parlance, and cannot charge an amount greater than the reasonable charge. If the physician does not take assignment, the physician’s fee may exceed the “reasonable charge” for the service provided, and the doctor may bill the patient for not only the difference between the reasonable charge and the federal payment, but also the difference between the actual charge and the reasonable charge as well. This is commonly referred to as “balance billing.”
Also enacted in 1965, Medicaid, Title XIX of the Social Security Act, 42 U.S.C. §§ 1396-1396v, established a federal-state cooperative cost-sharing program to provide necessary medical assistance to families and individuals with insufficient income and resources. While a state’s participation in Medicaid is not mandatory, once a state does enter into an agreement with the United States it receives federal funds for its Medicaid program. Participating states are required to comply with the Medicaid Act and its implementing regulations issued by the DHHS. 42 U.S.C. §§ 1396a, 1396c.
Under Medicaid, each state develops a schedule or methodology that establishes the fee that the state will pay a service provider for every item or service covered under the state’s Medicaid plan. Where Medicare and Medicaid cover the same services, the state Medicaid fee amount is almost always less than the reasonable charge for services that the federal government sets for Medicare reimbursement; it is also generally even less than the 80% of the reasonable charge figure that the government pays under Medicare’s Part B insurance plan. Service providers who participate in the Medicaid program are required to accept payment of the state-denoted Medicaid fee as payment in full for their services, i.e., they are required to take assignment, and may not attempt to recover any additional amounts elsewhere. Medicaid is essentially a payer of last resort, and one of the requirements of a state Medicaid plan is that it attempt to identify and collect other insurance or source of health care funding available to a Medicaid participant (i.e., a form of subrogation). 42 U.S.C. § 1396a(a)(25).
The Medicaid and Medicare statutes intersect for coverage of the population of the disabled or people 65 or over (eligible for Medicare) who are also poor (eligible for Medicaid). These people are called dual eli-gibles or crossovers. In addition, there is another group of whom we must take notice, called the “qualified medicare beneficiaries” or QMBs. As originally defined, QMBs included persons eligible for Medicare and who met certain statutory requirements of poverty, but who did not meet a state’s eligibility requirement for Medicaid; they are referred to as “pure QMBs.” Subsequently, the definition of QMB was changed so that ineligibility for Medicaid was removed; as such, the current definition of QMBs embraces two subsets of individuals: Medicare eligibles who are also eligible for Medicaid benefits (i.e., dual eligibles), and Medicare eligibles who are not eligible for Medicaid benefits but who meet certain criteria of poverty (i.e., pure QMBs).1 For the sake of clarity, we use the term QMBs to refer to both subgroups, and refer to one or the other subgroup only by its identified name.
While QMBs are, by definition, eligible for Medicare Part A enrollment and Part B insurance coverage, because they are impoverished there exists the very real danger that they will be unable to afford to buy themselves the Part B supplementary health coverage or pay Part A or Part B’s deductibles or coinsurance amounts. Thus, the people for whom the safety net is most needed are also those who, left to their own, could not place themselves within its embrace. Since the outset, at least as to dual eligibles, the Medicare and Medicaid statutes have addressed this problem. The response was to create a “buy-in” program, under which states participating under Medicaid use Medicaid funds (i.e., state funds for which federal matching funds under Medicaid are available) to pay the premiums to enroll the *1448QMB2 in the Medicare Part B insurance program (or the premium to enroll in Part A coverage for those people for whom the statute so required), and pay the deductibles and coinsurance payments that beneficiaries subsequently incurred under Part A or Part B. For dual eligibles, the state gets a real deal, because, given that Medicaid is treated as a payor of last resort, by enrolling dual eligi-bles for Part B coverage, the primary financial payment for services received comes from the federal government for any services that are covered under both Medicare and Medicaid. In other words, states use their Medicaid dollars, some of which are themselves federal in origin, to buy their QMBs into the federal program, thus shifting the primary payment for costs from the state Medicaid program to the federal Medicare program.
Thus, for a QMB, the state buys the individual into Medicare Part B insurance by paying the premiums for Part B insurance as well as the annual deductible. When the beneficiary incurs costs for services covered by Medicare (“Medicare services”) above the déductible, the federal government pays 80% of the reasonable costs of the Medicare services received. The central question in this lawsuit involves the remaining 20%, i.e., the copayment representing the difference between the federal government’s payment and the total amount of the “reasonable charge” that usually would be paid by the beneficiary but for the fact that the beneficiary is too poor to pay this amount herself. The difficulty arises from the fact that, as noted above, the Medicaid fee for a service is almost always lower than the Medicare reasonable charge. When that is the case, is the state required to reimburse the service provider for the entire 20% of the Medicare reasonable charge not covered by the federal payment, or is it only required to reimburse any difference between the federal 80% and the Medicaid reimbursement fee for that service? 3 In other words, is the formula for the state’s contribution:
Medicare reasonable charge — federal Medicare contribution or is it:
state Medicaid fee - federal Medicare contribution?
The selection of one formula over the other involves the characterization of the program as either primarily a Medicare program or primarily a Medicaid program. To say that the state is required to contribute the 20% difference is to see the program as being a Medicare program that is being partially financed with Medicaid dollars. To say that the state only has to contribute funds to bring the payment to the Medicaid amount, which means in some instances that the state need pay nothing, because the Medicaid cap is below the amount of the federal Medicare contribution, is to see the program either as a Medicaid program using primarily federal funds or, using the payor of last resort approach, to see it as a Medicaid program4 where the 80% federal Medicare amount is viewed simply as a third party “primary” insurance program (that is not paying the amount that it is statutorily supposed to pay), essentially ignoring the 20% beneficiary/state contribution, and viewing the state contribution as a “pure” Medicaid contribution rather than Medicaid funds going for reimbursement of Medicare services.
The position taken by the Secretary is that the state contribution requirement ends at the level of the state’s Medicaid fee cap. As a result, some states have altered their Medicaid plans relating to buy-ins accordingly. As of January 1, 1991, Virginia pays all of a QMB’s Medicare Part B premium and deductible, but pays a QMB’s coinsurance only to the extent that the Medicaid rate for the service provided exceeds the amount the fed*1449eral government pays under Part B. Thus, providers of Medicare services to QMBs do not receive the same payment for their QMB patients as for all other Medicare patients, but instead are eligible under the Virginia plan only to receive the greater of 80% of the Medicare fee or the full Medicaid fee, provided that the Medicaid fee is no greater than 100% of the Medicare fee.5
In addition to computing fees for Medicare services received by QMBs based on the Medicaid rate, the current Virginia plan does not directly reimburse physical therapy providers of the type who are the plaintiffs in this suit. The plan prohibits rehabilitation agencies from billing the Virginia Department of Medical Assistance Services (the state Medicaid administrator) directly for the amount owed for Medicare Part B deductibles and coinsurance on behalf of QMBs. Instead, the rehabilitation agencies must seek reimbursement for such amounts from the nursing facilities in which the beneficiaries are located, which are expected to submit those amounts to the state agency in their cost reports. The state agency then bundles these costs into a per diem rate paid to the nursing facility. Unfortunately, there is a per diem cap on nursing facility fees, and there is little prospect in reality that the bundling contemplated in fact occurs.
The Association, which is an association of rehabilitation service providers in Virginia, brought this suit seeking only injunctive relief against Kozlowski, head of the Virginia Medicaid program, and Shalala, head of the federal Medicare and Medicaid programs, under both the Medicare and Medicaid statutes directly as well as under 42 U.S.C. § 1983, alleging violations of the Medicare and Medicaid provisions in both the adoption of the Medicaid cap on QMB Part B reimbursement as well as in Virginia’s payment program to nursing facilities rather than directly to the actual providers. The state offered several affirmative defenses including lack of standing and Eleventh Amendment immunity. On cross motions for summary judgment, the district court found for the Association on both the cap amount as well as the payment system, and ordered Virginia to utilize the 20% Medicare figure as the reimbursement amount and to pay such reimbursement directly. Virginia and DHHS appealed, and this court stayed the mandate of the district court’s order pending resolution on appeal.
II.
We begin with Virginia’s two defenses to this suit, both of which may be handled with dispatch. First, Virginia claims that the suit must fail because it is barred by the Eleventh Amendment. The suit seeks prospective, injunctive relief only, rather than any form of retroactive compensatory damages, and is brought against Kozlowski, not the State. Such a suit is allowed under Ex parte Young, 209 U.S. 128, 28 S.Ct. 441, 52 L.Ed. 714 (1908), Edelman v. Jordan, 415 U.S. 651, 94 S.Ct. 1347, 39 L.Ed.2d 662 (1974), and their progeny, and this defense is completely meritless.
Second, Virginia again asserts that the Medicaid and Medicare Acts do not provide standing to the rehabilitation providers to bring this suit under § 1983. We need not tarry over this argument, for it already has been decided, both by this circuit and by the Supreme Court. In Virginia Hosp. Ass’n v. Baliles, 868 F.2d 653 (4th Cir.1989), aff'd sub nom. Wilder v. Virginia Hosp. Ass’n, 496 U.S. 498, 110 S.Ct. 2510, 110 L.Ed.2d 455 (1990), Virginia asserted that the Virginia Hospital Association lacked standing to challenge Virginia’s rates under the Boren Amendment, 42 U.S.C. § 1396a(a)(13)(A). Both this court and the Supreme Court rejected that contention, finding that the provision in question created enforceable rights on behalf of the service providers. The analysis set out in those opinions as to the Boren Amendment is *1450equally applicable in this instance to the related QMB provisions of 42 U.S.C. §§ 1396a(a)(10)(E), 1396d(a), 1396d(p). Where the state refuses to pay what the providers insist is the proper amount of the copayment for QMBs required under the Medicaid Act, the providers have standing to challenge the state’s interpretation of the relevant provisions.
III.
There can be no doubt but that the statutes and provisions in question, involving the financing of Medicare and Medicaid, are among the most completely impenetrable texts within human experience. Indeed, one approaches them at the level of specificity herein demanded with dread, for not only are they dense reading of the most tortuous kind, but Congress also revisits the area frequently, generously cutting and pruning in the process and making any solid grasp of the matters addressed merely a passing phase.
It is thus with some sympathy that we read the Secretary’s brief, which calls the court to defer to her expert judgment under the aegis of Chevron U.S.A. v. Natural Resources Defense Council, 467 U.S. 837, 104 S.Ct. 2778, 81 L.Ed.2d 694 (1984). Nevertheless, while Chevron is regularly cited by administrative agencies as a backstop to support their positions, it must be clear that that case did not replace Article III of the Constitution. As the opinion in Chevron makes clear:
When a court reviews an agency’s construction of the statute which it administers, it is confronted with two questions. First, always, is the question whether Congress had directly spoken to the precise question at issue. If the intent of Congress is clear, that is the end of the matter; for the court, as well as the agency, must give effect to the unambiguously expressed intent of Congress.9 If, however, the court determines Congress has not directly addressed the precise question at issue, the court does not simply impose its own construction on the statute, as would be necessary in the absence of an administrative interpretation. Rather, if the statute is silent or ambiguous with respect to the specific issue, the question for the court is whether the agency’s answer is based on a permissible construction of the statute.
Id. at 842-43, 104 S.Ct. at 2781-82 (citations and footnotes omitted). The task in the first instance for this court therefore is to examine the statute to determine whether the statute clearly speaks to the question of the amount of the Medicare copayment for which a state is responsible under the Medicare buy-in provisions. It is only if the statute is silent or ambiguous that we must look to the Secretary’s interpretation to provide guidance.
The particular provisions involved in this case have been the subject of repeated tinkering by Congress, and on each occasion the legislative history has provided some information that contradicts other information as to Congressional intent. As noted below, there is a particular element of “Congressional dicta” in the form of post-enactment legislative history involved in these eases that requires an accounting. Both the Secretary and the Association are to be commended on their briefs, and each offers a reasonably good explanation of the development of the statutes over time, but they are contradictory stories in important respects. Given the extensive changes that have occurred to these statutes over time, the only way to explain the present posture is to begin at the creation and work forward through those changes.
A.
The Social Security Amendments of 1965 included in a single massive bill the initial Medicaid and Medicare provisions. The buy-in provision appeared in § 121(a). It stated:
A State plan for medical assistance must—
‡ ‡ ‡ ‡
*1451(15) in the case of eligible individuals 65 years of age or older who are covered by either or both of the insurance programs established by [Medicare], provide—
(A) for meeting the full cost of any deductible imposed with respect to any such individual under the insurance program established by part A of such title; and
(B) where, under the plan, all of any deductible, cost sharing, or similar charge imposed with respect to any such individual under the insurance program established by part B of such title is not met, the portion thereof which is met shall be determined on a basis reasonably related (as determined in accordance with standards approved by the Secretary and included in the plan) to such individual’s income or his income and resources.
Social Security Amendments of 1965, Pub.L. No. 89-97, § 121(a), 70 Stat. 286, 1965 U.S.C.C.A.N. 305, 370-73 (codified prior to repeal at 42 U.S.C. § 1396a(a)(15)). As to Medicare Part A, this provision is straightforward: the state must pay the full deductible. As to Part B, the parties read it differently. The Association reads.it to mean that a state can pay the full amount of the deductible and cost-sharing under Part B; however, the state can also pay less than the full amount, but if it does so, it must still pay something of the amount due, and the amount it must pay is to be based on a figure reasonably related to the beneficiary’s income. In no event, anyway, can it not pay at all. The Secretary, on the other hand, interprets this provision to mean that state contribution towards Part B was completely optional.6
We believe it clear, based oii the plain language of the statute and the commentary in the legislative history that the Association’s interpretation is the correct one. The language of the statute seems clearly to indicate that if the state pays less than all of the deductible or cost sharing under the buy-in provision, “the portion thereof which is met shall be determined on a basis reasonably related ... to such individual’s income or his income and resources.” Two points confirm this reading. First, we believe that the legislative history eliminates any ambiguity that the statute contains. The general discussion of the bill includes the foEowing commentary:
A State medical assistance plan may provide for the payment in full of any deductibles or cost sharing under the insurance program established by part B of title XVIII. In the event, however, the State plan provides for the individual to assume a portion of such costs, such portion shall be determined on a basis reasonably related to the individual’s income, or income and resources and in conformity with standards issued by the Secretary. The Secretary is authorized to issue standards — under this provision which, it is expected, wiU protect the income and resources of the individual needed for his maintenance — to guide the States. Such standards shaH protect the income and resources of the individual needed for his maintenance and provide assurance that the responsibihty placed on individuals to share in the cost shaE not be an undue burden on them.
S.Rep. No. 404, 89th Cong., 1st Sess., 1965 U.S.C.C.A.N. 1943, 2020 (emphasis suppHed). The emphasized elements clearly disclose a Congressional intent that the language of the statute did not allow the states to opt out of the buy-in. Second, both the statute and the commentary provide for the Secretary to es-tabhsh rules as to how much less the State can pay if it pays less than everything. If the statute aEowed a state to pay nothing, it would be quite odd for the statute to then require the Secretary to establish strict regulations as to how much the state has to pay once it gets into the game. The whole point of the Secretary’s regulations keying the portion of State contribution to the beneficiary’s income and resources aims to protect the *1452poor, elderly individual from financial devastation as a result of illness; a reading of the statute allowing the state to opt out entirely vitiates the whole purpose of that provision by allowing the full burden of the copayment to fall on her shoulders.
Thus, from the beginning, the statute required state coverage of Part A coinsurance costs to be mandatory and total, while Part B coverage was also mandatory, but not necessarily total. If Part B coverage was less than total, it had to be keyed to the beneficiary’s income and resources in accordance with DHHS rules.
B.
In 1967, Congress tinkered with the statute. Section 285(a)(3) of the Social Security Amendments of 1967, Pub.L. No. 90-248, 81 Stat. 821, 1967 U.S.C.C.A.N. 923, 1031, amended 42 U.S.C. § 1396a(a)(15) to remove the differences between state requirements for the treatment of costs under Part A and Part B. It did so by rewriting the statute as follows:
A State plan for medical assistance must—
sjí sfc Hí # ❖
(15) in the case of eligible individuals 65 years of age or older who are covered by either or both of the insurance programs established by [Medicare], provide—
(A) for meeting the full cost of-any-deductible-imposed with respect-to any such individual-under the insurance program established by part A of such title;
(B) where, under the plan, all of any deductible, cost sharing, or similar charge imposed with respect to any such individual under the insurance program established by part B of such title is not met, the portion thereof which is met shall be determined on a basis reasonably related (as determined in accordance with standards approved by the Secretary and included in the plan) to such individual’s income or his income and resources.
Under this provision, Part A and Part B are treated uniformly, and the State may impose a deductible, but, as the accompanying Senate report notes,
the effect of the change would be to no longer require that a State plan meet the cost of the deductibles imposed under Part A of [Medicare] and to require that the plan relate any deductibles imposed under the hospital insurance program, as well as the supplementary medical insurance program, of [Medicare] to the income of the individuals covered under the plan.
S.Rep. No. 744, 90th Cong., 2d Sess. (1967), reprinted in 1967 U.S.C.C.A.N. 2834, 3142.7 Congress also broadened the coverage of the program to include all dual eligibles as opposed to simply those receiving cash assistance, see 1967 Amendments § 222(a), (b) (reprinted in 1967 U.S.C.C.A.N. at 1022-23), codified at 42 U.S.C. § 1395v. In addition, Congress made such buy-in agreements essentially mandatory for the states participating in the Medicaid program by providing that the federal government would not provide Medicaid matching funds to cover any costs incurred under the Medicaid program where the individual could have been enrolled in Medicare Part B but was not. Id. § 222(c), 1967 U.S.C.C.A.N. at 1023, now codified at 42 U.S.C. § 1396b(b).
Thus, after the 1967 amendments took effect, all dual eligibles could participate in the buy-in program; the States would not receive funds if they did not buy-in their dual eligibles; and the States’ required contribution under the buy-in included premiums, and deductibles and cost-sharing on either a full basis or a less than full basis complying with strict rules relating the amount of State contribution to the beneficiary’s income and resources. Thus it stood for almost 20 years.
C.
In 1986, Congress revisited this area, and it is here that the strongest disagreements *1453between the parties arise. An extensive series of amendments to the Social Security provisions was included in the Omnibus Budget Reconciliation Act of 1986, Pub.L. No. 99-509, 1986 U.S.C.C.A.N. (100 Stat.) 1874 (1986) (OBRA). One series of amendments was designed to allow and encourage the states to expand the coverage of their Medicaid programs to additional needy individuals whose income fell between the SSI limit and the federal poverty line. Because this expansion was entirely voluntary, however, the bill also included a backup provision, which was the initial introduction of QMBs (both' the population and the term) into the Medicaid buy-in provision of Medicare. Again at the option of the states, the amendments authorized them to use their Medicaid funds “for medicare cost-sharing ... for qualified medicare beneficiaries....” OBRA § 9403(a), 1986 U.S.C.C.A.N. (100 Stat.) at 2053 (codified as amended at 42 U.S.C. § 1396a(a)(10)(E)(i)). Qualified medicare beneficiaries were defined as individuals eligible for Medicare Part A insurance but not eligible for Medicaid, and who had incomes no greater than a state-determined limit (but that limit could not exceed the federal poverty line) and resources no greater than the maximum for benefits under the supplemental security income program. Id. § 9403(b), 1986 U.S.C.C.A.N. (100 Stat.) 2053-54 (codified as amended at 42 U.S.C. § 1396d(p)(l)).
Medicare cost-sharing was explicitly defined in the statute.
The term “medicare cost-sharing” means the following costs incurred with respect to a qualified medicare beneficiary:
(A) Premiums under part B ...;
(B) Deductibles and coinsurance [under Part A];
(C) The annual deductible [under Part B];
(D) The difference between the amount that is paid under [the relevant payment section of Part B] and the amount that would be paid under such section if any reference to “80 percent” therein were deemed a reference to “100 percent.”
Id, § 9403(d), 1986 U.S.C.C.A.N. (100 Stat.) at 2054 (codified at 42 U.S.C. § 1396d(p)(3)). Part (D) of the definition seems quite strongly to indicate that the cost-sharing requirement included all of the copayments, i.e., the difference between the federal 80% payment and 100% of the reasonable charge.
This is not the end of the matter, however. Another amendment provision stated that “the medical assistance made available to a qualified medicare beneficiary ... shall be limited to medical assistance for medicare cost-sharing ..., subject to the provisions of subsection (n) and [42 U.S.C. § 1396o ].” Id. § 9403(c), 1986 U.S.C.C.A.N. (100 Stat.) 2054 (codified at numeral VIII after 42 U.S.C. § 1396a(a)(10)(E)). The first half of this sentence makes perfect sense: it merely says that QMBs get state support for Medicare cost-sharing, and don’t get to “piggy-back” that into full Medicaid support they are not otherwise eligible to receive under the state Medicaid program. This is placed among a series of provisions set down in text form following 42 U.S.C. § 1396a(a)(10), which is the subsection that lists various groups that a state’s Medicaid plan must cover. All of these items, set off by roman numerals in the subsequent text, are intended to clarify that the fact that some groups are required to receive certain benefits under the state Medicaid plan doesn’t mean that other groups must be afforded identical benefits. The justification for all of these clarifiers arises from Congress’ initial concern that the states not provide better Medicaid benefits to the more well off than to the abject poor, and its response through the inclusion in the statute of a requirement that no group get a better set of benefits than any other group. Of course, with some groups, however, Congress itself wanted better or-different benefits provided, and once it recognized this tension was causing consternation among the states, it began in the 1967 amendments to insert these provisions to overcome the equality of benefits provision. See note 7, supm. Thus, this provision simply indicates, among the other clarifiers, that QMBs, who definitionally were not qualified for state Medicaid benefits, could obtain Medicaid assistance to get them into Medicare Part B and nothing more.
*1454The second half of the sentence, “subject to the provisions of [42 U.S.C. § 1896a(n) ] and [42 U.S.C. § 1396o ],” is somewhat more difficult to understand. As passed in 1986 under OBRA, 42 U.S.C. § 1396a(n) provides:
In the case of medical assistance furnished under this title for medicare cost-sharing respecting the furnishing of a service or item to a qualified medicare beneficiary, the State plan may provide payment in an amount with respect to the service or item that results in the sum of such payment amount and any amount of payment made under [Medicare] with respect to the service or item exceeding the amount that is otherwise payable under the State plan for the item or service for eligible individuals who are not qualified medicare beneficiar ries.
COBRA § 9403(e), 100 Stat. 2054-55 (emphasis supplied). The Secretary and Virginia lean very heavily on the word “may.” In their view, the fact that the statute says that the “State plan may provide payment” means that it may, but it doesn’t have to, pay an amount that exceeds the Medicaid fee schedule amount for the particular item or service in question. The Association, on the other hand, sees the “may” as being simply a lifting of a barrier; while states under Medicaid are not allowed to pay more than the plan amount, the statute here, to clarify any confusion about whether the state may pay the full 20% included as an item in the Medicare cost sharing definition, tells the state that it may in this instance go ahead and break the barrier. Although we believe that the Association’s explanation is highly plausible, given the connection between this provision and those allowance provisions set out in text form after § 1396a(a)(10), we believe that a better understanding appears for this provision.
Neither the Secretary’s nor the Association’s explanation grasps one of the central problems with this provision: at the time it was enacted, it only applied to pure QMBs and not to dual eligibles. Dual eligibles, definitionally distinct from the QMBs, were governed by 42 U.S.C. § 1396a(a)(15), which did not have any qualifier or reference to § 1396a(n). Thus, under the Secretary’s explanation of § 1396a(n), the pure QMBs would be subject to this discretionary cap, while the dual eligibles would not be. There is no logical reason for such a distinction, and we find no explanation in the legislative history to support such a differentiation. Under the Association’s approach, on the other hand, it is hard to explain why the states needed permission to break the Medicaid fee cap for QMBs when Congress didn’t apparently think before this time that such permission was needed for dual eligibles. Neither interpretation is particularly satisfying.
What both have in common, however, is what appears to be an erroneous assumption about the difference to which the statute actually refers. Both parties assume that the § 1396a(n)’s language, “eligible individuals who are not qualified medicare beneficiaries,” means that the statute is saying that the State may pay more for QMB payments under Part B than it pays for regular Medicaid payments for the same service. Thus, the comparison is Medicare Part B versus Medicaid. But “eligible individuals who are not qualified medicare beneficiaries” refers more logically to dual eligibles. This understanding of the statute suggests simply that the State may pay more for QMB payments under Plan B than it pays for dual eligibles under Plan B. While somewhat incongruous on first impression, the complicated statutory provisions of Medicaid explain this rule. While it appears that the state must pay all of the copayment and deductible under the Medicare cost-sharing definition for QMBs (with a small caveat, discussed below), under the dual eligible provision the state is allowed to impose a small charge to the beneficiary if it chooses not to pay the whole amount, as discussed in part II.A, supra. If a state exercised that option, it would be paying more for the QMB than for the dual eligible, and this provision appears to be merely stating that that is an allowable situation.
This approach is further confirmed by referring to the other provision to which the QMBs were “subject.” Without getting into much detail, 42 U.S.C. § 1396o relates to a state’s ability to impose certain charges on certain plan participants for certain services. *1455It allows for “nominal” charges, in the form of “deductions, cost sharing, or similar charge” to be made to QMBs for their Medicare Part B coverage through the Medicaid plan. This section provides greater harmony between the dual eligibles, who were covered totally or at a lower amount where the lower amount was keyed to income and resources, and QMBs, who could, under § 1396o, be charged some nominal amount. Because the amounts of nominal charges in either category were not necessarily set at the same levels, § 1396a(n) simply allowed for the situation where the QMB was charged less than the dual eligible, so that the state paid more for QMBs.
The legislative history of these 1986 provisions indicates in strong terms that Congress did not view the QMB provision to allow the state to pay only some portion of the copayment amount. In outlining the scope of the QMB program, the House report indicated that “States would be permitted to pay just for the Medicare Part B premium and the other Parts A and B cost-sharing requirements for Medicare beneficiaries.” H.R.Rep. No. 727, 99th Cong., 2d Sess., reprinted in 1986 U.S.C.C.AN. 3607, 3695. While the surrounding paragraphs were designed to explain how limited the states’ responsibility was for this program (which was being billed as a cheaper alternative than expanding Medicaid), and explained other ways the program was modest in character (“States would determine whether they wished to offer this assistance and, if so, where to set the income eligibility standards,” id.), it did not note that the State contribution could be discretionarily limited as well, certainly a strong selling point when attempting to emphasize the limited nature of the new option.
Perhaps more tellingly, the House report contains an extended discussion of the payment mechanics under this provision that contemplates a number of hypothetical situations, none of which include the state paying less than the whole 20%:
For elderly and disabled individuals whom the State chose to cover, the Medicaid program would pay for the Part B deductible and the beneficiary’s 20 percent coinsurance on Part B services. If the beneficiary uses a physician who takes assignment, Medicaid would pay the physician directly for the 20 percent coinsurance and the patient could not be billed for any amounts above the Medicare reasonable charge.' However, if the physician elects not to take assignment, the beneficiary would submit the claim for the 20 percent coinsurance requirement to the State Medicaid program and would be liable for an additional amount charged by the physician. The Committee therefore encourages the States to make available to the elderly and disabled assisted under this provision a list of physicians in their communities who will agree to accept assignment.
Id., 1986 U.S.C.C.A.N. at 3696 (emphasis supplied). The language clearly evinces a desire by the Committee to protect the eligible individuals; its discussion certainly would have noted their possible liability for part or all of the 20% if such liability existed. Thus, neither the discussion of the bill explaining the limited additional burden QMB buy-ins would pose, nor the discussion of the payments required of the QMBs themselves, mentions the possibility that this provision would allow the state to pay less than the full 20%; in contrast, the language overwhelmingly suggests that the full amount must be paid.
D.
In 1988, Congress acted thrice with respect to the buy-in program. First, it made the QMB buy-in provision mandatory rather than optional by striking out “at the option of the State” from the beginning of 42 U.S.C. § 1396a(a)(10)(E). Medicare Catastrophic Coverage Act of 1988, Pub.L. No. 100-360, § 301(a)(1), 1988 U.S.C.C.AN. (102 Stat.) 683, 748.8 At the same time, it expanded the definition of QMBs by increasing the maximum income level (to 100% of the poverty line, with no option for the states to set the eligibility line lower) and resource amount (from one to two times the supplemental *1456security income program maximum). Id. § 301(b), (e), 1988 U.S.C.C.A.N. (102 Stat.) at 748-49.
That is basically all that Congress did on its first consideration of the matter.9 The House Report accompanying the bill, however, goes far beyond a simple explanation of these minor amendments to the statute. It begins by explaining that Congress was lightening the load on state Medicaid programs by expanding the Medicare coverage of catastrophic care, and used this as its justification for imposing the mandatory QMB buy-in requirement on the States as a cost-effective use of the states’ saved resources. It included language, set out in the margin, that suggested that the states’ payments would cover all of the amounts of copayments.10 Yet it then proceeded to state, in unequivocal terms, an understanding of the buy-in program such that the states did not need to pay above the Medicaid cap:
The bill would require States to pay Medicare cost-sharing, including coinsurance, on behalf of eligible individuals. It is the understanding of the Committee that, with respect to dual Medicaid-Medicare eligibles, some States pay the coinsurance even if the amount that Medicare pays for the service is higher than the State Medicaid payment rate, while others do not. Under the Committee bill, States would not be required to pay the Medicare coin-suranee in the case of a bill where the amount reimbursed by Medicare — i.e., 80 percent of the reasonable charge — exceeds the amount Medicaid would pay for the same item or service. However, if a State chooses to pay some or all of the coinsurance in this circumstance, Federal matching funds would, as under current law, be available for this cost. For example, assume that a physician actually charges a “buy-in” patient $60 for performing a particular procedure; that Medicare recognizes $50 as the reasonable charge; and that the State Medicaid program only pays $35 for this procedure. Whether or not the physician takes assignment, Medicare will pay only 80 percent of $50, leaving a $10 coinsurance obligation for the beneficiary. However, since the State only recognizes $35 as the fee for the procedure in question, and since the Medicare program has already paid the physician $40, the State is not required to pay any of the $10 coinsurance. If the State chooses to pay some or all of the $10, however, its cost would qualify for Federal matching payments at the regular rate for services.
Id. at 61, 1988 U.S.C.C.A.N. at 884. While we understand the meaning of this language, the difficult question is as to its effect. First, it must be noted again that the only reading of the statute that allows a state to pay less than the full Medicare copayment amount emerges from § 1396a(n); that provision, however, did not apply to dual eligi-bles, and as such, the understanding stated in the report is clearly not correct. Second, as noted above, these amendments that the report accompanied were quite minor, dropping out “at the option of the State” and tinkering with the parameters of the QMB population. Thus, the actual legislation enacted was not the sort that could graft this *1457Medicaid cap onto what was previously there, The question thus becomes whether this report language should influence the interpretation as to previous enactments. We think that it should not. This wrenching change to a statute’s meaning that had been stable for 20 years points precisely to the pitfalls of relying on “post enactment legislative history,” which Justice Sealia recently has characterized, quite appropriately, as an oxymoron. United States v. Carlton, — U.S. -, -, 114 S.Ct. 2018, 2026, 129 L.Ed.2d 22, 34 (1994) (Sealia, J., concurring); see also Pereira by Pereira v. Kozlowski, 996 F.2d 723, 726-27 (4th Cir.1993). To the usual comparison of laws and sausages a new observation must be added: as our eating habits become healthier, and less filler is added to the making of sausage, so more is added to the making of law. See, e.g., Landgraf v. USI Film Prods., — U.S.-, - - -, 114 S.Ct. 1483, 1495-96, 128 L.Ed.2d 229, 250-51 (1994). While once a helpful source of guidance to Congressional intent, legislative history often may lead one astray. Given the narrow changes made to the provisions in question, we believe the quoted text to be little more than an attempt to alter the balance on the second front when someone could not win on the first. It is the intent of the enacting Congress, not that of a subsequent Committee or members of its staff, that controls. Oscar Mayer & Co. v. Evans, 441 U.S. 750, 758, 99 S.Ct. 2066, 2072-73, 60 L.Ed.2d 609 (1979).
Later in 1988, Congress again returned to the definition of a QMB. In the Technical and Miscellaneous Revenue Act of 1988, Pub.L. No. 100-647, 1988 U.S.C.C.A.N. (102 Stat.) 3342, Congress removed the requirement that a QMB not be covered under the state Medicaid program; the remaining definition thus was that the individual be eligible for Medicare and meet the income and resource limitations. Id. § 8434(a), 1988 U.S.C.C.A.N. (102 Stat.) at 3805. Under this definition, essentially -all dual eligibles and pure QMBs were covered.11 Finally, in an act providing technical clean-up for the Medicare Catastrophic Coverage Support Act from earlier in the year, Congress also re-, moved the old provision governing dual eligi-bles, 42 U.S.C. § 1396á(a)(15). See Family Support Act of 1988, Pub.L. No. 100-485, § 608(d)(14)(I), 1988 U.S.C.C.A.N. (102 Stat.) 2343, 2416. (Oddly, the repeal of the dual eligibles provision occurred- before the expanded QMB definition was passed, so for some time there was not perfect harmony.) Thus, by the end of 1988, the QMB provision had been expanded, first to include a larger pool of “pure QMBs,” and then to include the old dual eligibles, and the old dual eligibles provision was eliminated.
E.
In 1989, Congress revisited the area tangentially and with more problematic commentary. The problem that it was facing involved assignment. In the Budget Reconciliation Act, Pub.L. No. 101-239, § 6102, 1989 U.S.C.C.A.N. (103 Stat.) 2106, 2182, Congress required that payment for physicians’ services “to any individual who is enrolled under [Medicare Part B] and eligible for any medical assistance (including as a qualified medicare beneficiary ... ) with respect to such services under a State [Medicaid plan] may only be made on an assignment-related basis.” This prevents physicians from charging above the Medicare rate for the new expanded QMB community. The House report that' accompanied the bill continues to indicate an awareness of states applying the Medicaid cap in Medicare reimbursement. After noting that up until this point, dual eligibles are effectively covered by the Medicaid assignment rule, the report notes that “[t]he Medicaid programs typically pay the Medicare coinsurance only to the extent that their payment, plus the Medicare payment, does not exceed what the Medicaid *1458program would pay for the service in question.” H.R.Rep. No. 247, 101st Cong., 1st Sess. 364, reprinted in 1989 U.S.C.C.A.N. 1906, 2090. Describing the effect of the new provision, the report notes that “[i]t does not change the current policy regarding the amount which a Medicaid program must reimburse on such claims.” Id.
Once again, we are faced with difficult legislative commentary that contradicts the settled understanding of the statute’s provisions while not enacting, provisions that could in any way alter or affect the substantive provisions discussed in the commentary. Once again, we feel that fidelity to what Congress actually passed, and not what the report later attempts to explain is allowed, requires us to discard this post-enactment material.
From 1965 through 1986, Congress established a framework, incrementally expanded, under which the substantive provisions were developed and amended. Our reading of the statute, and the contemporaneous legislative history, discloses to us clear Congressional intent that state copayments under the buy-in program for either dual eligibles or pure QMBs be, except for optional nominal charges under § 1396a(a)(15) or later § 1396o, complete. Whatever ambiguity appears facially in reading the provisions in question, and we do not believe there to be much for those willing to plunge into the morass, does not remain once the contemporaneous legislative history is examined. While it may be that some in Congress, or on its staff, have had a subsequent change of heart regarding the matter; the only honest way to change the law is to actually change the law, not to drop contrary language into committee reports addressing totally unrelated provisions.
IV.
While it is not our duty as judges to establish policy but rather' simply to use established tools of statutory construction to determine the meaning of the laws passed by others, we note that the result reached above is in accord with all common sense. While such harmony is not a prerequisite to the law, it is a serendipitous benefit when it occurs, particularly in a statutory framework as complex as the one with which we are here involved.
As noted at the outset, our central task is to understand whether the present QMB buy-in program should be characterized as being primarily a Medicare program or a Medicaid program, and we believe that a careful reading of the statute’s evolution and related legislative history discloses that Congress, at all relevant points, viewed this plan as a straightforward extension of the Medicare program to Medicare Part B eligible individuals who were too poor to buy their way into this supplemental insurance program. In our view, it makes far more sense to call this a Medicare program that is being partly paid for with Medicaid funds rather than to call it a Medicaid program backing up federal Medicare program payments. Because the program covers pure QMBs, who definitionally are not eligible for regular Medicaid coverage, it is hard to say that this scheme is a Medicaid program when it includes such non-Medicaid-covered parties. Outside of the Medicare buy-in context, pure QMBs have no involvement with Medicaid whatsoever; they fall outside the income eligibility program, and, absent the statutory command to the states to expend Medicaid funds to purchase Medicare coverage for them, the states would not expend health care funds on them. Thus, it seems somewhat anomalous to say that this is a Medicaid program that includes people who are not otherwise eligible for Medicaid.
It also seems odd to call this a Medicaid program because in many instances the 80% federal reimbursement under Medicare is higher than the Medicaid fee cap, so that the amount reimbursed under Virginia’s present plan is set not by the Medicaid figure but rather by 80% of the Medicare figure. Thus, if it is a Medicaid statute, it is one with both different participants and different reimbursement rates than the “normal” Medicaid program of the state.
Finally, it could be seen as a statute with Medicare as the primary payor and Medicaid as the payor of last resort. The problem with this approach is that it would make *1459sense if the full Medicare amount were less than the Medicaid amount, so that we could say that the Medicare amount has been paid in full, and the Medicaid funds need not kick in. But that is not the case, and the figure used is not the full Medicare amount but rather the 80% federal payment amount. Under this conception, it is a Medicare statute with different, lower rates than the “normal” Medicare program.
Given all these complexities, it seems much more comprehensible that what Congress has constructed is an extension of the Medicare program, including both Parts A and B, that requires the states to pay any and all premiums, deductibles and copayments for the elderly poor, with the exception of the nominal charges allowed under § 1396o. The federal government pays the same amount for all these participants as it does for any other Medicare participant. It seems logical to simply see this as an instance where, because of the poverty of the QMB, the state rather than the individual shoulders payment for the cost-sharing provisions of the Medicare program. While the state is expending extra money for the pure QMBs in either scenario, since absent the required buy-in program it would not have anything to do with them, the states are in a winning situation financially because they are able to buy dual eligibles into the Medicare program, and Medicare then pays at least 80% of the cost of the beneficiary’s care when many if not all of those services otherwise would be financed through the state’s Medicaid funding. The only question is how good a deal the states get. Under Virginia’s approach, supported by DHHS, once Virginia pays the premium and coinsurance, it is often not required to pay anything more, because the Medicaid amount is lower than the 80% federal reimbursement. Under the Association’s approach, Virginia is still required to pay the 20% copayment, for which federal matching funds are also available, that the beneficiary is required to pay.12
It also should be noted that there is simply no way around the fact that there are going to be two tiers of repayment involved here; the only question is where the dividing line is placed. Under Virginia’s approach, service for all Medicare Part B beneficiaries except QMBs is repaid at 100% of the reasonable charge under the Medicare program. Service to QMBs, on the other hand, is repaid only at the Medicaid rate or 80% of the Medicare rate, whichever is greater. Service to pure Medicaid beneficiaries is paid at the Medicaid rate. Thus, the dividing line is essentially poverty: better payment goes to those serving the eligible “rich,” while worse payment comes from serving the poor of whatever age.13 Under the Association’s approach, on the other hand, the dividing line is purely age: better payment goes to providers serving those 65 or older no matter their income, while worse payment goes to the poor who are younger. Neither is a palatable choice, but it is one that we are not called upon to make: the legislative history reflects a pervasive Congressional concern with protecting the health of older Americans, and our analysis of the statute’s history confirms that Congress intended to provide maximum protection to the population of Americans 65 years of age or older, and that through the buy-in program, it established a mandatory program that guarantees that in-digency should not affect an individual’s participation in the Medicare Part B program. We thus join both of the other circuits that have passed on this question in holding that there can be no doubt but that the QMB is a Medicare enrollee, and that payment on her behalf must be made at' the Medicare rate. Pennsylvania Medical Soc’y v. Snider, 29 *1460F.3d 886 (3d Cir.1994); New York City Health & Hosp. Corp. v. Perales, 954 F.2d 854 (2d Cir.), cert. denied, — U.S. -, 113 S.Ct. 461, 121 L.Ed.2d 369 (1992).
Y.
Under the 1988 amendments to Virginia’s state Medica id Plan, “reimbursement will not be made directly to [rehabilitation] therapy providers for [rehabilitation] therapy services provided to Medicaid patients residing in long term care facilities_” Plan Amendment 88-08. Virginia adopted this amendment based on findings that the state had, on some occasions, been paying for such services twice, once to the long term care facility and once to the rehabilitation provider. After this amendment, payment of rehabilitation providers for services rendered to pure Medicaid patients comes not from the Virginia Department of Medical Assistance Services but rather is funnelled through the long term care facilities in which the patients reside. Long term care facilities receive a per diem payment for each Medicaid patient, and the payment to the rehabilitation sendee providers is bundled into that block payment. As to pure Medicaid patients, the Association does not contest this system of financing its constituents’ services.
As to QMBs, however, although the Medicare reimbursement amount for rehabilitation services is greater than is that under Medicaid, there is no differentiation in the per diem reimbursement to the long term care facility based on whether the services provided are financed at the Medicare or Medicaid rate, so that the rehabilitation providers do not receive any additional reimbursement from the nursing homes for QMBs, thus vitiating the providers’ right to receive the full reasonable charge for their services under Medicare. The Association points out that the rehabilitation services providers receive direct payment from the federal government to cover 80% of the Medicare Part B reasonable charge for services they provide to QMBs. Under the current scheme, however, which theoretically bundles the 20% copayment into the per diem amount the state pays to the nursing facilities, the service providers effectively receive nothing. The Association argues that payments for QMB services are Medicare payments rather than Medicaid payments, that the long term care facility is a stranger to the relationship, and that they are entitled to receive payment directly under the statute, rather than bundled through the nursing facilities as is the practice with pure Medicaid patients.
With respect to “pure” QMBs, such a bundling policy is not applicable. Pure QMBs are not “regular” Medicaid patients, and the hospital per diem simply does not encompass them. They are not considered “Medicaid patients” for these purposes. The Secretary seems, at least implicitly, to acknowledge this conclusion. See Br. for the Secretary of Health and Human Services, at 29-30.
The Secretary argues that as to dual eligi-bles, however, bundling is allowable. In support, it cites to 42 U.S.C. § 1396a(a)(32), which requires that a state plan must “provide that no payment under the plan for any care or service provided to an individual shall be made to anyone other than such individual or the person or institution providing such care or service,” with only a few exceptions not relevant here. From this it argues that the nursing facility can be considered to be the institution providing such care or service, so that payment directly to the nursing facility is allowable. In support, it cites to the Medicaid statute and regulations that require that nursing facilities provide such services to Medicaid residents through their own employees or through an arrangement with an outside rehabilitation agency. 42 U.S.C. § 1396r(b)(4)(A)(i).
As an initial matter, we note first the logical fallacy in the Secretary’s analysis: just because one is required to see that service is provided does not make one the provider of the service. While the long term care facility is required to provide certain service under the Medicaid Act, it is not, in fact, the actual provider of the services in question. In fact, the federal government’s payments are made not to the nursing facility but rather to the rehabilitation service providers directly. While the nursing facility may be required to provide the service under the Medicaid Act, in this instance it contracts *1461with these third parties who “provide” the service.
Beyond this, our principal problem with the Secretary’s analysis is that it relies too heavily on the premise that, as with the pure Medicaid patient, it is Medicaid, not Medicare, service that is involved here. As to the pure QMB population, the rehabilitation services that they receive from Association members are not “Medicaid services” because they are not Medicaid-eligible except insofar as the state is required to buy them into Medicare as a condition of its participation in the Medicaid program. As to the dual eligibles, who are both Medicare and Medicaid patients, the characterization is similarly difficult. While it is convenient that the Medicaid statute requires services similar to those being reimbursed here under Medicare, if such services were not required under Medicaid the Secretary’s reasoning would fail because there would be no way to say that the nursing facility is required to provide them. The particular facts of this case thus cloud the picture to some extent: it is helpful to understand the fact that, in a situation in which Medicaid does not cover a certain service but Medicare does, the reimbursement is to the provider; the only characterization of the payment can be as a Medicare reimbursement. The Medicaid statute does not govern who the “provider” is in such circumstances, nor should it govern here. While the fact that these rehabilitation services are required under Medicaid means that the nursing facilities satisfy their Medicaid requirements, it is difficult to understand how that affects the characterization of the funding of these services or who is deemed the provider.
Virginia makes a similar argument, and it highlights the problem more acutely: it states that “Virginia recognizes no one as a Medicaid provider unless he has executed a written provider agreement with the Virginia Department of Medical Assistance Services.” Br. of Appellant Kozlowski at 12. From this premise, Virginia argues that, since the Asso-iation's members do not have provider agreements, they cannot receive funds directly. Applying this theory generally suggests that any health service provider of whatever type who provides Medicare Part B services to QMBs will not be eligible for reimbursement of the 20% copayment from Virginia unless she also has executed a written Medicaid provider agreement with the state. Thus, under this approach, a provider who does not participate in both the Medicare and Medicaid programs, or who for whatever reason has not signed a written agreement with the State, cannot receive reimbursement of the Medicare Part B copayment because she is not a Medicaid eligible service provider. Simply speaking, this approach makes no sense, and converts a simple 20% copayment into a bureaucratic nightmare. Thus, while neither the Secretary’s nor Virginia’s argument causes many concerns when simply approached on the particular facts of the ease, a full understanding of the inadequacy of each when viewed from a more general perspective undermines their analytic soundness. It seems largely irrelevant that the nursing facility is required to provide these services under Medicaid; the fact of the particular arrangement under Medicaid should not be of import in deciding whom to reimburse for Medicare procedures.
We are left to determine how Virginia appropriately complies with the requirement of 42 U.S.C. § 1396a(a)(32) that it not pay “for any care or service provided to an individual ... to anyone other than such individual or the person or institution providing such care or service.” Although Medicaid funds are in question, they are being used to pay the Medicare Part B copayment for services provided under the Medicare Act. As such, the proper approach looks not to the Medicaid statute but rather to the Medicare statute to determine who is the appropriate entity for payment.14 After the 1989 amendments, payment under Medicare Part B for “physicians’ services” for all *1462QMBs may only be made on an assignment-related basis. 42 U.S.C. § 1395w-4(g)(3)(A). Physicians’ services are defined to include the type of rehabilitation services involved here. Id. § 1395w-4(j). They are considered “outpatient physical therapy services” under 42 U.S.C. § 1395x(p), which are services “furnished by a provider of services, a clinic, rehabilitation agency, or a public health agency.” As rehabilitation agencies, the plaintiffs members fall within this definition and receive payment directly from Medicare earners. They are the direct billers and should be the direct payees. This reasoning harmonizes the Medicaid requirement that payment only be made to the individual or service provider by finding that, as to Medicare reimbursement, it is the Medicare statute that governs whether the rehabilitation agency should be considered a service provider. Under that statute, the rehabilitation providers are the “providers” of services, not the long term nursing facilities in which the patients reside.
VI.
For the reasons stated above, we are of the opinion that the judgment and order of the district court should be, and hereby are, affirmed.
AFFIRMED.
. Specifically, QMBs are defined as individuals who are eligible for Medicare Part A benefits, have incomes not exceeding the federal poverty line, and whose resources do not exceed twice the amount set as the maximum for receiving benefits under the supplemental security income program. 42 U.S.C. § 1396d(p)(l).
. Although the buy-in program originally only extended to dual eligibles, it was extended in the 1980s to include pure QMBs as well, as discussed below.
. For example, say that for a particular service, the reasonable charge under Medicare is $100. The federal government reimburses $80 (assuming the deductible has been exhausted). If the Medicaid rate for that service is $90, does the state have to pay $20 or $10? And if the Medicaid rate for that service is $75, does the state pay $20 or nothing?
.We note in passing the incongruity of characterizing this as a Medicaid program when the pure QMBs are definitionally not eligible for Medicaid assistance.
. Neither the Secretary nor the Association addresses the hypothetical situation in which the Medicaid fee is greater than the full Medicare reasonable charge. Under the Secretary’s theory, the state presumably would pay the greater amount; when pressed at oral argument on this point, the attorney for Virginia declared that it would certainly comply with this counterfactual scenario if it ever occurred, and that it would not insist that the Medicare amount capped its payment requirement.
The judiciary is the final authority on issues of statutory construction and must reject administrative constructions which are contrary to clear congressional intent. If a court, employing traditional tools of statutory construction, ascertains that Congress had an intention on the precise question at issue, that intention is the law and must be given effect.
. Whatever the answer as to the amount of the State's payment, it should be noted that the buy-in requirement did not apply to all dual eligibles. Under § 102 of the 1965 law, the Secretary was authorized to enter into buy-in agreements only as to Medicaid beneficiaries who were receiving cash assistance from the states, not from the entire pool of Medicaid beneficiaries. See 1965 U.S.C.C.A.N. at 334. This was codified at 42 U.S.C. § 1395v. The 1967 Amendment broadened this provision to allow buy-in agreements for all dual eligibles.
. Beside this commentary, other portions of the Senate report confirm our view that Congress understood that state payments under Part B, and now Part A, if less than total had to be keyed to the dual eligible's income and resources. See 1967 U.S.C.C.A.N. at 3019 (discussing comparability requirement problem and exception to allow states to "meet[ ] part or all of the deductibles, cost sharing, or similar charges under part B"); id. at 3136 (same).
. According to the accompanying House Report, only one state had decided to avail itself of the optional approach created under the 1986 provisions.
. It also did some clean up, including providing a slightly cleaner definition of what constitutes the medicare cost-sharing that the state must provide to QMBs. Id. § 301(d), 1988 U.S.C.C.A.N. (102 Stat.) at 749. While the definition is more elegantly drafted, it does not change the contents in any significant way except as to payments for prescribed drugs.
. Thus, the introduction to the report stated that "States would be required to pay the Medicare premiums, deductibles and coinsurance for all Medicare enrollees with incomes at or below the Federal poverty guideline and assets at or below twice the Supplemental Security Income guidelines.” H.R.Rep. No. 105(11), 100th Cong., 2d Sess. 36, reprinted in 1988 U.S.C.C.A.N. 857, 859. Later, in describing treatment of dual eligi-bles, the report notes that "States also pay Medicare deductibles and coinsurance on behalf of their dual eligibles.” Id. at 57, 1988 U.S.C.C.A.N. at 880. And in describing the effect of the new mandatory QMB buy-in requirement, it states that
the States would be required to pay the Medicare premiums, deductibles, and coinsurance for all elderly and disabled individuals.... States would not be required to provide these individuals the full range of Medicaid benefits that they offer to categorically or medically needy beneficiaries; instead, they would be required only to pay Medicare cost-sharing on their behalf.
Id. at 60, 1988 U.S.C.C.A.N. at 883.
. The House Conference Report makes this explicit:
The conference agreement clarifies that individuals who, as of January 1, 1989, will be mandatorily eligible for coverage of their Medicare cost-sharing (qualified Medicare beneficiaries) are individuals who are entitled to Medicare, whose income meets specified standards, and whose resources do not exceed twice the amount allowed under the SSI program, whether or not they are otherwise eligible for Medicaid.
H.R. Conf. Rep. No. 1104, 100th Cong., 2d Sess. 284, reprinted in 1988 U.S.C.C.A.N. 5048, 5344.
. An outstanding question, which the Secretary tries to avoid, concerns the gap, under the Secretary's and Virginia’s approach, between the state's reimbursement up to the Medicaid fee and Medicare’s full reasonable charge. Under their approach, up to 20% of the Medicare reasonable charge is not paid by the states under the buy-in. Obviously, if the beneficiary is still liable for it, the entire purpose of the program is undermined. If the buy-in is treated as a Medicare program, so that the state is required to pay the full 20% difference, the question is moot.
. Of course, pure QMBs are not considered “poor” by state Medicaid .standards, since they do not qualify for Medicaid; this leaves the anomalous situation where the pure QMBs are eligible for Medicare coverage and not eligible for Medicaid coverage, but are treated as Medicaid patients, but not Medicare patients.
. Because the appropriate statute is the Medicare Act rather than the Medicaid Act, we find it unnecessary to consider the arguments both sides make concerning the First Circuit’s analysis as to the appropriate "provider” under the Medicaid Act in Danvers Pathology Associates v. Atkins, 757 F.2d 427 (1st Cir.1985). That case did not involve either dual eligibles or QMBs, and was strictly confined to an interpretation of the Medicaid statute.
