In this сase arising under the Employment Retirement Income Security Act (“ERISA”) of 1974, 29 U.S.C. § 1001 et seq., Joe Ham-mack sued Baroid Corporation, demanding coverage under the company’s health plan for his wife’s hospital bills. The district court concluded that the Medicare as Secondary Payer (“MSP”) statute, 42 U.S.C. § 1395y(b), does not apply and аwarded Hammack $124, a fraction of what he had sought. Finding no error, we affirm.
I.
When Hammack retired from his job with NL Industries in 1985, at age 55, he was under an NL Industries health plan that qualifies as a benefit plan under ERISA. 1 The plan provided, in relevant part:
If you retire either directly from active employment or from an approved company disability plan under a cоmpany sponsored retirement plan, Option A of the medical plan will continue at no cost to you and your eligible dependents____ Once you or your spouse becomes eligible for Medicare, benefits will be calculated by reducing covered medical expenses by the amount of Medicare payments. In calculating benefits payable, it is assumed that both you and your dependents have both part A and B Medicare coverage.
At the time of Hammack’s retirement, his wife, Ann, was over 65.
In 1988, Ann Hammack incurred outpatient medical bills totaling close to $1,000. Baroid paid part of these bills, another insurеr paid part, and the Hammacks paid the remainder.
At some point before February 1989, Bar-oid notified the Hammacks that they were best advised to purchase Medicare, because *268 the benefits under the Baroid plan would be calculated as though they had enrolled in Medicare, regardless of whether they actually had. In February 1989, the Hammacks contacted the Social Security Administration. Shortly thereafter Ann Hammack paid the required premium and enrolled in Medicare Part B but not in Part A.
Ann Hammack was hospitalized twice in 1989: once from April 6 through April 9, and once from June 9 through June 14, resulting in bills totaling $5,670.26. Medicare covered part of these expenses. Baroid covered part as well, but it calculated the benefits as though Ann Hammack were enrolled in both Part A and Part B, resulting in reduced payouts to the Hammacks.
II.
Joe and Ann Hammack sued Baroid in state court, 2 and Baroid removed to federal court. Following a bench trial, the court concluded that Barоid did not abuse its discretion in determining the Hammacks’ benefits. The court ordered Baroid to pay the Hammacks $124 — the amount of a bill that Baroid stipulated it had wrongly failed to pay. The court submitted factual findings and conclusions of law in a seven-page order. On the final page the court stated: “FINAL JUDGMENT should issue. It is so ORDERED.” The court did not, however, file a separate document noting that this was a final judgment.
Twenty months after this order was issued, Joe Hammack returned to the court and requested entry of judgment. The court granted the motion and issued a single-page, separate document reflecting the final judgment.
We address two questions. First we must decide whether we have jurisdiction — or whether Hammack, by waiting twenty months to seek a separate document noting the entry of final judgment, waived his right to appeal. The second question — assuming we have jurisdiction — is whether the district court erred in concluding that, because Ham-mack was a retiree, the MSP statute did nоt apply.
III.
Baroid charges that Hammaek’s lengthy delay in seeking entry of judgment constitutes waiver of his right to appeal. Under Fed. R.App. P. 4(a)(1), a civil litigant ordinarily has thirty days after “entry of the judgment or order appealed from” to file notice of appeal. This rule in turn refers us to Fed. R. Crv. P. 58 and 79(a). Rule 58 contains what is known as the “separate document” rule: “Every judgment shall be set forth on a separate document. A judgment is effective only when so set forth and when entered as provided in Rule 79(a).” Rule 79(a) requires the court to record the entry of a final judgment in its civil docket.
A.
Baroid does not dispute that Hammack complied with the plain language of the rule by filing his notice of appeal within thirty days. 3 Instead, Baroid argues that, when a party that has received a final judgment waits so long before seeking a separate document, we should construe the delay as waiver of the right to appeal. Such a rule, Baroid suggests, will promоte certainty and finality in litigation. This question is res nova in this circuit.
Baroid’s position is not entirely lacking in legal support. In
Fiore v. Washington County Community Mental Health Cir.,
We believe it appropriate, absent exceptional circumstances, to infer waiver where a party fails to act within three months of the court’s last order in the case____ A party wishing to pursue an appeal and awaiting the separate document of judgment from the trial court can, and should, *269 within that period file a motion for entry of judgment.
Id. at 236. The court explained that this three-month window would ensure that a failure to appeal was a matter of “choice, not confusion.” Id. at 236 n. 11. Baroid urges us to adopt Fiore’s rule and apply it in this case to quash Hammack’s appeal. 4
B.
The Supreme Court recognized waiver of the separate document requirement in
Bankers Trust Co. v. Mallis,
In construing rule 58, we have been faithful to the teaching of
Mallis
and have avoided interpreting the rule to extinguish appeals. For example, in
Baker v. Mercedes Benz of N. Am.,
While we have yet squarely to consider the First Circuit’s approach in Fiore, the logic of our easelaw counsels its rejection. To the extent that we have permitted waiver of the separate document requirement, it has been in situations similar to that in Mallis — where neither party objects to the taking of an appeal and strict аpplication of the rule would prove a pointless and burdensome exercise. We have never employed the doctrine to extinguish a party’s right of appeal, even when, as Baroid suggests, doing so might promote finality and certainty. 6
*270 Accordingly, we reject Fiore and hold that a party’s delay in seeking a separate document judgment cannot constitute waiver of his right to appeal. Under the plain language of Fed. R.App. P. 4(a)(1) and Fed. R. Civ. P. 58, the thirty-day period for taking an appeal does not begin to run until the court has issued a separate document and records entry of the final judgment in its civil docket. Should a court fail to issue a separate document, a party seeking finality remains free to request one.
IV.
We now turn to the merits. Ham-mack argues that the provision of Baroid’s plan under which a retiree’s benefits are reduced by the amount of potential Medicare payments is invalid because it violates the MSP statute. He contends that the district court erred by deeming the statute inapplicable to retirees.
The district court concluded — and Hammack concedes — that Baroid’s plan endows its administrator with discretionary authority to make eligibility determinations and construe the plan’s terms.
7
When an administrator is vested with such authority, its dеcisions are reviewed by a federal court for abuse of discretion.
Firestone Tire & Rubber Co. v. Bruch,
In reviewing the district court’s legal conclusions, such as whether the plan administrator abused its discretion, our standard of review is
de novo.
We review the district court’s findings of fact for clear error.
Sunbeam-Oster Co. Group Benefits Plan v. Whitehurst,
A.
Under the MSP statute as it read in 1988 and 1989 when Ann Hammack received medical treatment, Medicare could not be the primary coverage for “employees” with private coverage through their employer. The statute provided:
A group health plan—
(I) may not take into account, for any item or service furnished to an individual 65 years of age or older at the time the individual is covered under the plan by reason of the current employment of the individual (or the individual’s spouse), that the individual is entitled to benefits under this subchapter under section 426(a) of this title, and
(II) shall provide that any employee age 65 or older, and any employee’s spouse age 65 or older, shall be entitled to the same benefits under the plan under the same conditions as any employee, and the spouse of such employee, under age 65.
42 U.S.C. § 1395y(b)(l)(A)(i) (1988). Thus, the statute prohibited employers from designating Medicare as the primary payer for active employees — the working aged — -but not for retirees.
See Provident Life & Accident Ins. Co. v. Leonard,
Hammack argues that a 1993 amendment expanded the statute to include retirees. Presently, the statute applies to individuals with “current employment status,” which is defined as an employee, an employer, or anyone “associаted with the employer in a business relationship.” 42 U.S.C. § 1395y(b)(l)(A)(i), (b)(l)(E)(ii). But even if we were to apply the amended version of a statute to claims that arose before the amendments were enacted, it is not evident *271 that the result would differ, for courts have continued to hold the MSP statute inapplicable to retirees. 8
B.
Hammаck deploys two additional arguments. First, he suggests that any interpretation excluding retirees is inconsistent with the MSP statute’s purpose, viz., to reduce Medicare outlays by ensuring that private insurers pay first. 9 Yet theories of underlying intent or purpose cannot trump statutory language — and Hammack points to no such languаge commanding the result he demands.
In fact, the text of the statute indicates precisely the opposite: By limiting the statute’s scope to “employees,” Congress consciously excluded retirees. The MSP statute reversed the order of payment in certain situations where Medicare beneficiariеs enjoy an alternate source of health care coverage; it does not follow that the statute reversed the order of payment in all situations.
Second, Hammack argues that Baroid’s decision to reduce payments under its plan by the amount the participants could receive under Medicare was contrary to the plan’s intent of providing free medical care to its former employees. Setting aside the question how Hammack elicits such a sweeping intent, we do not agree that, by designating Medicare as primary payer for retired employees, Baroid is thereby precluded from limiting its obligаtions.
In sum, we agree with the district court that because Hammack was a retiree, the MSP statute does not apply. Accordingly, the provision in Baroid’s plan is not void under the statute, and the administrator did not abuse its discretion in discounting Ham-mack’s payments by the amount of potential Medicare benefits. 10
AFFIRMED.
Notes
. Baroid is NL Industries’s successor-in-interest and has assumed responsibility for the health plan.
. Ann Hammack does not appeal the district court judgment.
. Nor does Baroid dispute that the seven-page order cannot qualify as a "separate document" for purposes of Fed. R. Civ. P. 58.
. Only one other circuit has considered this rule. In
Rubin v. Schottenstein, Zox & Dunn,
No. 96-3017, 1998 U.S.App. LEXIS 9004, at *20 (6th Cir. May 7, 1998) (en banc), the court expressly rejected
Fiore's
approach and adoрted the panel’s view that while construing a three-month delay as waiver of the separate document requirement "may be a pragmatic resolution of the problem, it is not supported by the rules or the Supreme Court’s statements on the issue."
Rubin v. Schottenstein, Zox & Dunn,
.
See also Seiscom Delta, Inc. v. Two Westlake Park (In re Seisсom Delta, Inc.),
Where ... a party is severely prejudiced by lack of entry of a judgment becаuse it is unclear whether a final judgment has indeed been entered, rule 58 should be applied mechanically ... to favor the right of appeal by allowing the party in jeopardy to appeal from the separate-document judgment once one has been entered.
Id.
.We note that Hammack's 20-month delay is unusually long. In
Baker,
. Specifically, the plan provides that the administrator shall have general responsibility for "Determination of Benefit eligibility" and “all powers necessary to carry out the provisions of the pertinent documents and ... the exclusive right to construe such documents and to determine and resolve any question that may arise in connection with its funding, application or administration. ..."

.Hammack's “argument” seeking attorney's fees is limited to a breezy request at the conclusion of his brief. He appears not to have raised this claim in the district court, nor has he chosen to call to our attention any evidence Or precedent in support of his claim. His request is therefore denied.
