to recover Medicare costs. First, in 1968, the General Counsel of the Federal Bureau of Health Insurance (which administered Medicare at that time) issued an Opinion to that effect, stating that Medicare payments are “insurance benefits,” as distinguished from the health care “provided directly by the federal government” to which MCRA clearly applied. See Subrogation Rights Under Medicare, For the Defense, Apr. 1970, at 44 (Defs.’ Mem., App. J at 67). Second, in 1979, HCFA issued a ruling that, in eases in which the Government was liable for an injury under the Federal Tort Claims Act (“FTCA”) and Medicare paid the medical expenses, the victim could retain all payments the Government made to her under the FTCA. See HCFA Ruling 79-4 (1979), reprinted in 52 Fed.Reg. 26,088, 26,090 (1987). The rationale underlying this ruling (that Medicare was not to receive any reimbursement for the care it had provided to the injured person) was that Medicare was “in the nature of social insurance.” Id.
Since MCRA’s enactment in 1962, neither HCFA nor any other administrative agency has ever indicated, or even suggested, that MCRA applies to Medicare or FEHBA expenses. These agency statements and silences, taken in conjunction with the absence of regulations that would formalize and facilitate the Government’s recovery of Medicare or FEHBA costs under MCRA, lend further credence to Defendants’ position that MCRA was never meant to apply to Medicare or FEHBA expenses.
3. Application of the Brown & Williamson Principles
Having considered both the legislative history and agency interpretations of MCRA, the Court’s final task is to apply the Brown & Williamson principles enunciated in Section IV.A.1 to discern what Congress’ intent was in enacting MCRA in 1962 and amending it in 1996. Based on this examination, the Court must conclude that MCRA does not provide the Government with a cause of action to recover Medicare or FEHBA expenses. The legislative history and relevant agency conduct, when taken together, overwhelmingly support the notion that MCRA was never intended to be used in the way the Government now advocates.
First, it is significant that even though FEHBA existed before MCRA’s enactment, MCRA makes no reference to FEH-BA — either in the statute itself, in the legislative history or in agency interpretations.
Second, it is striking that the Government had never, prior to the initiation of this lawsuit in 1999, attempted to recover Medicare or FEHBA costs under MCRA. Although the Government is correct that mere nonuse of a statute cannot cause the Government to forfeit powers granted thereunder, see United States v. Morton Salt Co., 338 U.S. 632, 647-48, 70 S.Ct. 357, 94 L.Ed. 401 (1950), nonuse can be highly significant. When, despite many opportunities to do so, a government agency refuses to take advantage of the wide-ranging powers seemingly implicated by a statute’s plain language, courts may presume that Congress did not intend the statute to be given the meaning that its language, in a vacuum, might imply. See Brown & Williamson, 120 S.Ct. at 1306-07; see also Bankamerica Corp., 462 U.S. at 130-31, 103 S.Ct. 2266 (holding that where Government had not applied a statute in a particular way in 60 years, it had effectively acknowledged that it lacked authority to do so); Bunte Bros., 312 U.S. at 352, 61 S.Ct. 580; National Classification Comm. v. United States, 746 F.2d 886, 892 (D.C.Cir.1984). This is particularly true in this instance, where the broader interpretation of MCRA (i.e., that every conceivable type of government expenditure, even under Medicare and FEHBA, can be recovered under MCRA) had never been advanced by any government entity until thirty-seven years after the statute’s enactment.
Third, Congress is presumed to act “against the backdrop” of HCFA’s interpretations of the statutes HCFA is entrusted to administer. See Brown & Wil-
