You should know before you retire which TRICARE programs best suit your and your family's needs. Once you retire, you will only have 90 days from your retirement date to enroll in a TRICARE plan to continue TRICARE coverage. If you retire from active duty and are under age 65, you can choose either TRICARE Prime (where available) or TRICARE Select (available worldwide). If you live overseas, you may seek coverage under the TRICARE Select Overseas. For more information, visit Enroll or Purchase a Plan on the TRICARE websiteand read the Retiring from Active Duty Brochure on the TRICARE website. For information about all TRICARE plans, visit the Military.com TRICARE section.
