Tricare Prime Overseas Program

Elizabeth Tower in London Houses Big Ben

The Tricare Prime benefit is available overseas. The program serves active duty members, activated reserve & guard members, and their command sponsored dependents. The Tricare Prime Overseas program is considered minimum essential coverage under the Affordable Care Act

Who is Eligible

Enrollment in Tricare Prime Overseas is not automatic, family members must enroll before receiving care. To be eligible, family members must:  

  • Be eligible in DEERS
  • Be listed on their permanent change of station (PCS) orders or relocate on service sponsored/funded orders

How it Works

You will coordinate with your Primary Care Manager (PCM), who will provide most of your care, if there is specialized care your PCM cannot provide, they will refer you to a healthcare provider in your local foreign area that contracts with International SOS, the contractor authorized by Tricare to provide foreign services.


There are no enrollment fees for Tricare Prime overseas, there are no copyament fees as long as you get care from your PCM or a PCM referred provider, if you go to a provider without a PCM referral you will be liable for point-of-service fees.

To Enroll

You must enroll by calling your regional center or by mailing a completed application to International SOS, you cannot enroll online. Please visit the Tricare Prime Overseas enrollment page for more information.

TOP enrollment begins on the date of acceptance of your enrollment package. ADFMs may enroll at any time. Enrollment continues until they choose to disenroll, or are transferred to another Tricare region or area, or until they become ineligible for TOP Prime or the Tricare program. There are no enrollment fees, co-payments, or deductibles for using TOP Prime.

Moving: If you are scheduled for a permanent change of station (PCS) move, you will remain enrolled in Prime for a maximum of 60 days from the date you leave your current Tricare region (in the U.S. Territories or overseas).
