New TRICARE Regional Contractors

Starting January 1, 2018, there will be new regional contractors for the new East and West regions.

Your TRICARE benefit is the same regardless of where you live, but there are different customer service contacts for each region. Each region is administered by a contractor to provide you with health care.

East Humana Military
West Health Net Federal Services


Your new regional contractor will contact you in the fall. Your regional contractor is your main resource for customer service, claims processing, and prior authorization for certain health care services. We have added improvements in the delivery, quality, and cost of your health care from previous contracts.

Will I be able to keep my doctors and other health care providers?

It depends. If you have:

  • A TRICARE Prime plan and your regional contractor is changing, it will depend on if your doctor and other health care providers are in the new network.
  • Any other plan, you will be able to see your doctors, as long as they are TRICARE authorized. 

The new 2018 TRICARE Network Provider Directories are available now:

  • East Network Providers
  • West Network Providers 
  • Last Updated 10/24/2017
