TRICARE For Life is one of the best retirement health benefits in America — but it only works if you set up Medicare correctly. Here’s exactly how the two fit, what it costs in 2026, and the one step you can’t skip.
TRICARE For Life (TFL) is Medicare-wraparound coverage for military retirees and eligible family members. When you keep Medicare Part A and Part B, TFL automatically pays after Medicare on services they both cover — which is why so many retirees pay little or nothing out of pocket. There is no enrollment fee for TFL. Your only real cost is the Medicare Part B premium.
To keep TRICARE For Life, you must be enrolled in both Medicare Part A and Part B once you’re eligible (usually at 65). If you turn down Part B, your TRICARE coverage stops. There’s no “TFL without Part B.” We make sure your Part B is active before your birthday so coverage never lapses.
Higher earners may pay an income-related (IRMAA) surcharge on Part B. We’ll help you understand whether that applies to you.
| Step | What happens |
|---|---|
| 1. You see a provider who accepts Medicare | You usually show your Medicare card and TFL coverage. |
| 2. Medicare pays first | Medicare processes the claim as your primary payer. |
| 3. The claim goes to TFL automatically | In most cases the claim is sent to the TFL processor for you — no paperwork. |
| 4. TFL pays the remainder | For services both Medicare and TRICARE cover, you generally owe little to nothing. |
For most retirees, no. TRICARE For Life already acts as the wraparound that a Medicare Supplement (Medigap) would normally provide, so buying both usually means paying twice for the same protection. The bigger priorities for TFL retirees are getting Part B set up on time and choosing how to handle prescriptions. If you do not have TFL, a Medigap plan is often the smarter route — see Medigap for veterans →
TFL includes a separate TRICARE pharmacy benefit, so most retirees do not need a standalone Medicare Part D drug plan. We’ll confirm what fits your medications.
The Part B deductible ($283 in 2026) applies before Medicare begins paying, so it can fall to you. After that, TFL typically picks up the remaining cost-shares on covered services.
This is where timing gets tricky and mistakes get expensive. Talk to us before you make any changes so your TFL stays intact.
