The everyday experience
How Original Medicare and Tricare for Life work together
Once you turn 65 and enroll in Medicare Parts A and B, your coverage doesn't get smaller — it gets stronger. Here's how the two programs coordinate in everyday life, drawn directly from the 2026 handbooks.
Why Original Medicare + TFL is the foundation
Coverage you've earned, working as designed
For most retired military, Original Medicare paired with Tricare for Life delivers nationwide access, low out-of-pocket costs, and overseas protection — without changing networks or providers.
See any Medicare-accepting doctor
TFL has no network. As long as your provider participates with Medicare, you're covered — nationwide, no referrals.
Hospital stays and outpatient care
Part A covers inpatient. Part B covers outpatient. TFL fills in deductibles and coinsurance after Medicare pays its share.
Prescriptions through TRICARE
You don't need Medicare Part D. The TRICARE Pharmacy Program (Express Scripts) provides drug coverage at military, retail-network, and mail-order pharmacies.
Overseas coverage included
Medicare generally doesn't cover overseas care. TFL becomes your primary payer abroad through the TRICARE Overseas Program.
Claims usually crossover automatically
When you see a Medicare-participating provider in the U.S., the claim crosses over from Medicare to WPS automatically. You rarely file paperwork.
Most costs covered for routine care
For services covered by BOTH Medicare and TFL at participating providers, your typical out-of-pocket cost is $0.
Real-world scenarios
Four common situations and how the bills get paid:
Scenario 1
A primary-care office visit
1. Medicare pays
Medicare Part B pays 80% of the Medicare-approved amount after your annual Part B deductible.
2. TFL pays
TFL pays the Part B deductible (if not yet met) and the remaining 20% coinsurance.
3. You pay
Typically $0 out of pocket.
Scenario 2
An inpatient hospital stay
1. Medicare pays
Medicare Part A covers the hospital stay subject to the Part A deductible per benefit period.
2. TFL pays
TFL covers the Part A deductible and any Medicare coinsurance for the stay.
3. You pay
Typically $0 out of pocket.
Scenario 3
A prescription at a retail pharmacy
1. Medicare pays
Original Medicare doesn't include outpatient drug coverage (that's Part D — which you don't need).
2. TFL pays
Use a TRICARE retail network pharmacy. You pay a small copay set by TRICARE (often $0 at military pharmacies and lower at mail order).
3. You pay
TRICARE copay only — no Medicare cost-share.
Scenario 4
Care while traveling overseas
1. Medicare pays
Doesn't cover most care outside the U.S. and U.S. territories.
2. TFL pays
Becomes your primary payer through the TRICARE Overseas Program. You may need to pay upfront and file a claim.
3. You pay
Cost-shares apply per TRICARE Overseas rules — see the TFL Handbook for details.
Three things to confirm before any new appointment
- 1
The provider accepts Medicare assignment.
If they don't accept Medicare, TFL won't pay either. Always ask before booking.
- 2
They file with Tricare for Life as secondary.
Most Medicare providers do — claims crossover automatically through WPS.
- 3
You're up to date in DEERS.
Your TFL eligibility is verified through DEERS at every claim.
