TRICARE For Life generally does cover your Medicare Part A and Part B deductibles, as long as the service is covered by both Medicare and TRICARE.

Quick Scoop: Short Answer

  • For services covered by both Medicare and TRICARE, TRICARE For Life usually pays the Medicare deductibles and coinsurance, leaving you with little or no out‑of‑pocket cost.
  • If Medicare does not cover a service but TRICARE does, you may have to pay TRICARE’s own deductible and cost‑share instead of a Medicare deductible.
  • If a service is not covered by either program, you pay the full bill yourself.

How TRICARE For Life Works With Medicare

  • TRICARE For Life is “Medicare wraparound” coverage for eligible military retirees and family members who have Medicare Part A and Part B.
  • In the U.S. and territories, Medicare pays first and TRICARE For Life pays last, filling most of the gaps like deductibles and coinsurance when both cover the service.

Does TRICARE For Life Pay the Medicare Deductible?

  • The official TRICARE guidance explicitly states that TRICARE For Life does pay the Medicare Part A and Part B deductibles when the service is covered by both programs.
  • Educational Medicare‑TRICARE resources similarly explain that TRICARE For Life covers the Medicare deductible and coinsurance, often reducing your annual out‑of‑pocket risk to near zero for covered services.

When You Might Still Pay Something

  • If Medicare denies a service but TRICARE covers it, Medicare pays nothing and TRICARE becomes primary; in that case you may owe the TRICARE deductible (for example, a per‑person annual deductible) and copayments.
  • When you are overseas in places where Medicare does not apply, TRICARE For Life becomes primary, and you are responsible for TRICARE’s own deductible and cost‑shares instead of any Medicare deductible.

Forum & “Latest News” Angle

  • Recent explainers and discussions in 2024–2025 keep reinforcing the same message: people with TRICARE For Life usually do not need an extra Medigap policy because TFL already covers Medicare deductibles and coinsurance for jointly covered services.
  • Online forum threads where retirees compare notes often show confusion at first, but the consistent takeaway from experienced users is that, for standard Medicare‑covered care in the U.S., they typically see little to no bill after Medicare and TRICARE For Life process the claim.

TL;DR: If your care is covered by both Medicare and TRICARE, TRICARE For Life does pay your Medicare deductible; you mainly need to watch for services only one (or neither) program covers and for TRICARE deductibles when TRICARE is primary (such as overseas).
