Overseas Residence (Living Abroad with Medicare & TFL)
How Medicare, TRICARE For Life, and VA care work when a retiree lives outside the United States.
Also known as: living abroad, expat retiree, overseas retiree
Quick answer
Medicare generally does not pay for care received outside the United States and its territories. TRICARE For Life, however, continues to cover most overseas care — but it does so as the first payer (not secondary) because there is no Medicare claim to coordinate with. VA care abroad is limited to the Foreign Medical Program for service-connected conditions.
Why it matters
Without understanding this flip, retirees abroad often assume their cost-sharing works the same as it does in the U.S. It does not — and they still must pay the Part B premium to keep TFL.
Why this matters at age 65
Many retirees relocate or split time abroad after retirement. Dropping Part B 'because Medicare doesn't work overseas' is the single most damaging mistake — it cancels TFL worldwide.
When you'll encounter it
Retirement relocation, long-term travel, or residence in a foreign country.
Impact on Medicare
Original Medicare rarely pays for foreign care (limited exceptions for emergencies near the U.S. border or on a ship within 6 hours of a U.S. port).
Impact on TRICARE For Life
TFL becomes the primary payer overseas and pays at TRICARE-allowable rates. You typically pay the provider up front and file a paper claim with the TRICARE Overseas Program.
Impact on Medicare Advantage
Most MA plans cover emergencies only abroad and have no overseas network — usually a poor fit for full-time expats. Original Medicare + TFL is almost always the better structure overseas.
VA Healthcare considerations
VA care abroad is limited to the Foreign Medical Program (FMP), which covers only service-connected conditions.
Military-specific context
DEERS must reflect a valid overseas address, and TRICARE Overseas Program (administered by International SOS) handles claims and provider referrals.
Common misconceptions
- "I can drop Part B since Medicare doesn't pay overseas anyway." — Dropping Part B terminates TFL — your only health coverage abroad — and creates lifetime late penalties if you return to the U.S.
- "TFL works the same overseas as in the U.S." — Overseas, TFL is primary, you usually pay up front, and you submit paper claims for reimbursement.
Common mistakes to avoid
- Letting your DEERS address lapse, which can suspend overseas TFL claims processing.
- Assuming a Medicare Advantage plan will cover routine overseas care.
- Failing to keep itemized receipts and translated invoices for TOP claims.
Real-world scenario: A retired Marine living in Portugal has knee surgery at a private clinic.
He pays the clinic up front, submits the itemized bill to TRICARE Overseas Program, and TFL reimburses at the TRICARE-allowable amount. Medicare pays nothing. Because he kept Part B, his TFL stayed active.
What should I do?
- 1Keep both Part A and Part B active — even though Medicare won't pay overseas.
- 2Update your overseas address in DEERS via milConnect before you move.
- 3Register with the TRICARE Overseas Program (International SOS) for provider referrals.
- 4Keep all itemized receipts, translated when possible, for claim filing.

- I live overseas full-time. How does Medicare + TFL work?Keep paying Part B to keep TFL. Use TFL as your primary payer overseas (Medicare doesn't pay abroad). File paper claims with International SOS.
- Does TRICARE For Life work overseas?Yes. Overseas, TFL acts as your primary payer because Medicare generally doesn't pay outside the U.S. You'll usually pay the provider up front and file a paper claim with TFL overseas.
- Who pays first, Medicare or TRICARE For Life?Medicare pays first for any service it covers. TFL pays second. The claim usually crosses over automatically — you should never pay out of pocket up front.
- If I move overseas, can I drop Part B since Medicare doesn't pay there?Don't. Dropping Part B ends TFL the same day. Re-enrolling later triggers a permanent late penalty plus a coverage gap.
- 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.
