TriWest Expansion

Expanding Our Role

As mentioned in our letter to providers, TriWest will be assisting the Department of Veterans Affairs (VA) in administering the VA Community Care program across the entire nation. If you are a provider who is new to TriWest, welcome! If you are a TriWest contracted provider, please reference all information on our existing Provider Portal.

We have a team of representatives at 1-866-245-3820 waiting to assist you with any questions you may have as we temporarily expand our Community Care responsibilities into the territory previously handled by Health Net Federal Services (HNFS). We hope the information on this page will provide you with more details regarding this transition.

Your participation in the network is greatly appreciated. Thank you for joining our mission and proudly caring for Veterans within your community!

Why TriWest?

TriWest Map of VA Expansion RolloutTriWest has worked collaboratively with VA from the start of Community Care across 28 states in the western and southern parts of the U.S. Along with VA, TriWest addressed challenges within these programs to improve implementation and operations to better serve Veterans.

TriWest’s performance today is strong. With a current network of more than 1 million community care provider access points, we have systems in place to rapidly build a provider network within the regions previously handled by Health Net.

Why This Change?

  • VA’s contract with Health Net, which covers half of VA’s Community Care regions, ended on September 30, 2018.
  • VA determined the only way to quickly and effectively perform the work for network development and administrative services is to tap into the support of TriWest, which already performs the same services in the other half of VA’s regions.
  • VA expanded TriWest’s services to the entire nation. TriWest collaboration has ensured that network and administrative services are meeting Veteran and community provider needs.
