You do not have to re-enroll every year to continue TRICARE Prime Remote Overseas coverage, but certain events will cause you to be disenrolled.
Any change in the sponsor's status (e.g., active duty to retired or Guard/Reserve deactivation) will cause an automatic disenrollment.
If the sponsor retires, TRICARE Prime Overseas is no longer available. If you continue to live overseas, you're covered by TRICARE Select Overseas.
If you lose eligibility for TRICARE, your TRICARE Prime Remote Overseas coverage will automatically end.
