TRICARE Prime Overseas

TRICARE Prime Overseas is a managed care option in overseas areas near military hospitals and clinics. 

  • Enrollment is required.
  • There are no enrollment fees.

Who Can Participate

  • Active duty service members
  • Command-sponsored active duty family members
  • Activated National Guard and Reserve members
  • Command-sponsored family members of activated National Guard and Reserve members

Retirees and their family members can’t enroll in TRICARE Prime Overseas.

How It Works

  • You’ll get most care from your assigned primary care manager at a military hospital or clinic.
  • Your PCM refers you to a specialist for care they can’t provide and works with International SOS, the overseas contractor, for authorization, when needed.

What You Pay

Your costs depend on your beneficiary category.

  • Active duty service members: No enrollment fees or out-of-pocket costs for covered care
  • Active duty family members: No enrollment fees or network copayments. Point-of-service fees may apply.

Point-of-Service Fees

If you get nonemergency care without following referral rules, you’ll pay point-of-service fees instead of your usual . These fees are much higher.

POS fees include:

  • An annual deductible: $300 per individual or $600 per family
  • Cost-shares: 50% of the TRICARE-allowable charge after you meet your POS deductible
  • Additional charges: You may have to pay amounts charged by non-network providers above the TRICARE-allowable charge.

POS fees don’t count toward your annual catastrophic cap.

Note: If you’re an active duty service member, POS fees don’t apply to you. But you must still follow your plan’s referrals and requirements.

Is TRICARE Prime Overseas right for you?

TRICARE Prime Overseas is only available to active duty service members (including National Guard and Reserve members) and command-sponsored family members.

  • If you’re on active duty, you have to enroll in TRICARE Prime Overseas where it’s available.
  • Family members must be command-sponsored to enroll.
  • Family members who aren’t command-sponsored or who choose not to enroll in TRICARE Prime Overseas may enroll in TRICARE Select Overseas.
