TRICARE and Medicare Part B: What Military Retirees Must Know

You must enroll in Part B to keep TRICARE for Life. Without Part B, you lose TRICARE for Life benefits entirely. There is no penalty concern if you enroll on time — the concern is losing TRICARE if you don't.

When This Applies

  • You are a military retiree turning 65
  • You have TRICARE and are transitioning to TRICARE for Life
  • You are wondering if TRICARE covers you without Part B
  • You want to maintain military health benefits

Frequently Asked Questions

Do I need Part D with TRICARE?
No. TRICARE provides creditable drug coverage, so you don't need a separate Part D plan and won't face a Part D penalty.
Is TRICARE for Life free?
Yes — there's no enrollment fee for TRICARE for Life. But you must pay your Part B premium.
What happens to TRICARE Prime at 65?
TRICARE Prime ends at 65. You transition to TRICARE for Life, which requires Part A and Part B.
