Military retirees: TRICARE For Life and Medicare
If you're a military retiree or eligible family member, a few points matter most:
- You need Part A and Part B. TRICARE says TFL coverage is automatic if you have Medicare Part A and Part B. Turning down or dropping Part B can put that coverage at risk.
- Medicare usually pays first. For covered care in the U.S., Medicare pays its share and the claim goes to TRICARE, which pays what remains. If you have employer coverage from a current job, the order changes.
- Think before adding another plan. Some TFL beneficiaries keep Original Medicare and rely on TFL as their wraparound. Others look at Medicare Advantage. Your choice affects how claims are paid and which providers you can see, so get advice specific to your situation.
