TRICARE Regions


TRICARE is available worldwide and is managed in four separate regions: North, South, West and Overseas.

TRICARE Regional Contractors
TRICARE has contracted with managed care support contractors in each region to provide you with health care services and support beyond what's available at military treatment facilities (MTFs) to include:

  • Establishing provider networks
  • Operating TRICARE Service Centers
  • Providing customer service call centers
  • Providing administrative support, such as enrollment, care authorization and claims processing
  • Distributing educational information to beneficiaries and providers

Click on your region in the left-hand navigation to learn more about each region including your contractor's customer service information.

Other Contractors
The regional contractors do not typically provide assistance for pharmacy, the three TRICARE dental plans, the US Family Health Plan or TRICARE For Life (in the U.S. and U.S. Territories). These services are provided by other contractors.

Health Plan Options
TRICARE offers several health plan options and while they are similar stateside and overseas, there are differences in qualifications depending on where you live.
