Beneficiaries Using TRICARE Retired Reserve

If you’re eligible for Medicare Part A, you aren’t required to have Medicare Part B to purchase TRICARE Retired Reserve.

Even though you aren’t required to have Medicare Part B, we strongly encourage you to sign up for Part B when you’re first eligible. If you don’t, you may be required to pay the Medicare Part B late-enrollment penalty.
