## Definition The TRICARE Overseas Program (TOP) is the Department of Defense's health care program for eligible U.S. military members, retirees, and their families living in any country or territory outside the 50 United States and the District of Columbia.

## What it means in practice Living overseas changes how you access military healthcare, primarily because the network of civilian providers is managed by a single international contractor, **International SOS**. While the core benefits of TRICARE remain consistent, the TRICARE Overseas Program (TOP) is divided into several sub-plans: **TOP Prime**, **TOP Prime Remote**, **TOP Select**, and **TOP TFL (TRICARE For Life)**.

For active duty service members (ADSMs) and their command-sponsored dependents, **TOP Prime** mimics the stateside Prime experience. Care is typically managed at a military hospital or clinic (Military Treatment Facility) on base. If care cannot be provided on base, International SOS coordinates a referral to a local host-nation provider. In TOP Prime, there are typically no out-of-pocket costs for covered medical services. For those in remote locations without a nearby base, **TOP Prime Remote** provides similar coverage but allows for more flexibility with civilian providers, though pre-authorization is almost always required.

For retirees and families who are not command-sponsored, **TOP Select** functions like a Preferred Provider Organization (PPO). You have the freedom to see any licensed host-nation provider, but you will likely have to pay upfront and file a claim for reimbursement. In 2026, TOP Select beneficiaries are subject to annual deductibles (for Group A, approximately $150 per individual or $300 per family) and cost-shares (typically 20% to 25% of the allowable charge after the deductible is met).

A critical distinction for TOP users is **medical evacuation (MedEvac)**. If you are enrolled in TOP Prime or TOP Prime Remote and require urgent care that is unavailable locally, TRICARE covers the cost of transportation to the nearest capable facility. However, TOP Select beneficiaries may be responsible for these costs if the evacuation is not deemed a medical necessity under specific TRICARE criteria, making supplemental travel insurance a common recommendation for retirees abroad.

## Related terms * **International SOS:** The current contractor responsible for managing the TRICARE network, claims, and customer service for all overseas regions. * **Command-Sponsored:** A formal status for dependents that allows them to be listed on a service member's overseas orders, granting them eligibility for TOP Prime and full transition benefits. * **Host-Nation Provider:** A civilian doctor, hospital, or specialist located in a foreign country who provides care to TRICARE beneficiaries. * **Non-Command Sponsored:** Dependents who move overseas at their own expense; they are generally ineligible for TOP Prime and must use TOP Select. * **OCONUS:** An acronym for "Outside the Continental United States," the geographic area covered by the TRICARE Overseas Program. * **TOP TFL:** TRICARE For Life coverage for beneficiaries who are entitled to Medicare and live overseas; notably, Medicare does not pay for care outside the U.S., making TRICARE the primary payer.
