Provider Acceptance
Whether a specific provider agrees to bill Medicare and/or TFL — and under what terms.
Also known as: accepts Medicare, accepts TRICARE
Quick answer
Provider acceptance covers three independent questions: Does the provider accept Medicare assignment? Are they non-PAR or opt-out? Do they file TFL claims as a courtesy? You need to answer all three before booking.
Why it matters
TFL pays automatically only if Medicare paid first AND the provider files (or you file) a TFL claim. Mismatched acceptance creates the bulk of TFL billing headaches.
Why this matters at age 65
MTF providers handled everything. Civilian providers vary widely — verifying acceptance is the single best front-end protection you have.
When you'll encounter it
Before every first appointment with a new provider.
Impact on Medicare
Determines whether Medicare pays at all.
Impact on TRICARE For Life
Determines whether TFL can wrap around as secondary.
Common misconceptions
- "'Accepts Medicare' means they'll file TFL too." — Not always — TFL crossover is automatic, but courtesy billing for non-crossover items is a provider choice.
Common mistakes to avoid
- Confirming Medicare acceptance but not asking about opt-out status.
- Not confirming the provider will submit overseas claims to International SOS.
Real-world scenario: A new physical therapist 'takes Medicare' but is opted out.
Medicare pays $0, TFL pays $0, patient pays the full $180 per session.
What should I do?
- 1Ask three questions: Do you accept Medicare assignment? Are you opted out? Do you file TFL?

- TFL Overseas CoverageOutside the U.S., TFL becomes the primary payer because Medicare generally doesn't pay overseas.
- 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.
- 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.
- I'm turning 65. What should I do first?About 3 months before your 65th birthday, sign up for Medicare Parts A and B at SSA.gov. TRICARE For Life activates automatically once both are effective and DEERS is current.
- 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.
- How does the Medicare-to-TFL claim crossover work?Medicare processes the claim, pays its share, and electronically forwards it to WPS using your sponsor SSN. WPS pays TFL's share directly to the provider — usually within 2–3 weeks.
