Beneficiaries Using TRICARE Reserve Select

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

Even though you aren’t required to have Medicare Part B, we strongly encourage you to enroll in Part B when you’re first eligible.

• Although TRICARE treats you as an active duty family member while enrolled, Medicare doesn’t consider your sponsor to be actively employed by the military.
• If you don’t enroll in Part B when you’re first eligible, you may be required to pay the Medicare Part B late enrollment penaltyYour monthly premium for Part B may go up 10% for each full 12-month period that you could have had Part B, but didn't sign up for it..
