Active Duty Family Members

If entitled to Medicare Part A, you're not required to have Medicare Part B to keep your TRICARE benefits. You must have Part B to keep TRICARE once your sponsor retires.

Special Enrollment Period

The special enrollment period is available while your sponsor is on active duty or within the first eight months of his or her retirement.

  • If you enroll in Part B after your sponsor retires, you will have a break in TRICARE coverage.
  • To avoid this break, enroll in Part B before your sponsor retires.

If entitled to Medicare Part A because you have End Stage Renal Disease, you're encouraged to keep Part B when first eligible because you won’t be eligible for a special enrollment period.

If you decline or terminate Part B coverage, you may enroll in Medicare Part B during the general enrollment period which occurs each year January 1 through March 31. The Medicare Part B premium surchargeAn additional 10% for each 12-month period that you were eligible to enroll in Part B, but didn’t will apply.

General Enrollment Period

If you don't enroll in Medicare Part B during the special enrollment period, your next opportunity to enroll in Part B is during the general enrollment period (January 1 - March 31 each year). Your Part B coverage and TRICARE coverage will start on July 1 of the year you enroll. You may also be required to pay the Medicare Part B premium surchargeAn additional 10% for each 12-month period that you were eligible to enroll in Part B, but didn’t.
