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 penalty.
