TRICARE For Life (TFL)
The wraparound secondary health coverage for Medicare-eligible military retirees, spouses, and survivors — no premium, no enrollment fee.
Also known as: TFL, Tricare for Life, TRICARE for Life
Quick answer
TRICARE For Life (TFL) is the Department of Defense's Medicare-wraparound program administered by the Defense Health Agency (DHA) and processed by Wisconsin Physicians Service (WPS). It acts as the secondary payer to Medicare for TRICARE-eligible beneficiaries who have both Medicare Parts A and B. TFL is not a separate insurance policy you buy — it is an automatic benefit that activates when DEERS reflects your Medicare enrollment.
Why it matters
TFL is the single most valuable retirement health benefit for career military families. It eliminates almost all out-of-pocket cost on Medicare-covered services, has zero monthly premium, and adds coverage Medicare doesn't include (like overseas care). The only cost to keep it is your Medicare Part B premium.
Why this matters at age 65
TFL replaces TRICARE Prime, TRICARE Select, TRICARE Plus, or US Family Health Plan the day you become eligible for Medicare — usually the first of the month you turn 65. There is no application to fill out, but you must (1) be enrolled in Medicare Parts A and B and (2) have current information in DEERS. Missing either one means losing TRICARE entirely at 65.
When you'll encounter it
TFL activates automatically the day Medicare A and B both become effective. Every doctor visit, hospital stay, and pharmacy fill after that runs through the Medicare → TFL coordination process.
Impact on Medicare
Medicare always pays first in the U.S. for TFL beneficiaries on Original Medicare. TFL only sees claims that have already been processed by Medicare via the automated CMS-to-WPS crossover.
Impact on TRICARE For Life
TFL is the program itself. It pays the Medicare deductible and coinsurance for services covered by both Medicare and TRICARE, typically leaving the beneficiary with $0 out-of-pocket.
Impact on Medicare Advantage
If you join a Medicare Advantage plan, TFL stays active and becomes secondary to the MA plan — same wraparound role, just behind a different primary payer. The MA plan must still be billed first; TFL helps cover the plan's copays for services TRICARE also covers.
VA Healthcare considerations
TFL and VA Healthcare are completely separate. TFL does not pay for care delivered at a VA facility, and the VA does not bill TFL. Many retirees use VA for service-connected care and TFL + Medicare for everything else — keeping both maximizes flexibility.
Military-specific context
TFL is administered by DHA under the same authority as other TRICARE programs. The TRICARE For Life Handbook (updated annually by DHA) is the authoritative document on benefits, claims, and overseas coverage. Eligibility is sponsored — your military service entitles your spouse and certain survivors to TFL once they reach Medicare eligibility.
Common misconceptions
- "I have to enroll in TFL." — TFL is automatic. Make sure DEERS is current and you have Parts A and B — that's all.
- "TFL costs money." — Zero enrollment fee and no monthly premium. You only pay the Medicare Part B premium (to Medicare, not TRICARE).
- "I need a Medicare Supplement (Medigap) policy with TFL." — No. TFL is your Medigap. Buying one is wasted money — Medigap pays after Medicare, and so does TFL.
Common mistakes to avoid
- Letting DEERS get out of date — TFL claims will deny even if you have Medicare.
- Declining Part B to avoid the premium — this terminates TFL on the spot.
- Buying a Medigap policy 'just in case' — it duplicates what TFL already does.
- Assuming TFL pays at VA facilities — it does not.
Real-world scenario: A retired Army E-8 turns 65 in June. She enrolls in Medicare A and B effective June 1.
Her TRICARE Prime coverage ends May 31 and TFL activates June 1 with no application. Her July doctor visit is billed to Medicare (who pays 80% of approved amount); the claim crosses over electronically to WPS, which pays the 20% coinsurance and deductible under TFL. She owes $0.

- Is there an enrollment fee for TRICARE For Life?No. TFL has no enrollment fee and no monthly premium. The only premium you pay is for Medicare Part B.
- What does TRICARE For Life actually cover?TFL is a wraparound. For services Medicare and TFL both cover, TFL pays nearly all remaining cost-shares. For Medicare-only services, TFL still acts as secondary. For TFL-only services (very few), TFL pays as primary.
- Does TFL have a catastrophic cap?Yes. The TRICARE annual catastrophic cap protects you from unlimited out-of-pocket costs on TFL's portion of care.
- What do I actually pay out-of-pocket on TFL?For services covered by both Medicare and TRICARE, almost always $0. For TRICARE-only services, you owe a small deductible plus a percentage cost-share until you hit the annual catastrophic cap.
- Does TFL cover long-term care or a nursing home?No. Medicare and TFL only cover short-term skilled care after a qualifying hospital stay. Custodial long-term care (assisted living, nursing home for daily living help) isn't covered by either.
