Frequently Asked
Do I really need Medicare Part B?
Yes. Without Part B, you lose TRICARE For Life. There is no workaround.
Yes. Medicare Part B is non-negotiable if you want to keep TRICARE For Life.
The Defense Health Agency requires Medicare-eligible TRICARE beneficiaries to be enrolled in both Parts A and B. The day you drop Part B (or fail to enroll), TFL ends.
This trips up a lot of retirees because the Part B premium feels like a new bill they didn't have before. But here's the math:
- The standard Part B premium in 2026 is roughly $202.90/month (higher with IRMAA).
- In exchange, you keep TFL — which covers virtually all of your Medicare cost-shares.
- Without Part B, a single hospital stay could cost tens of thousands of dollars out-of-pocket.
If the Part B premium is a financial strain, look at a Medicare Advantage plan with a Part B giveback. Veteran-focused MA plans can return $50–$170+/month back to your Social Security check while preserving TFL as a wraparound.
What does not exempt you from needing Part B:
- Having TRICARE Prime or Select before 65 — irrelevant after Medicare eligibility.
- Having VA healthcare — VA is a separate system that doesn't coordinate with TFL.
- Still working — only true employer coverage (yours or your spouse's) qualifies for a Special Enrollment Period.

- Will TRICARE pay my Medicare deductible?Yes. For services covered by both Medicare and TRICARE at participating providers, TFL typically covers the Medicare deductible and coinsurance — leaving you with $0.
- Should I choose Medicare Advantage?It's an optional consideration. A veteran-focused MA plan can lower your Part B premium and add dental/vision/hearing — while TFL continues to wrap around it.
