Working with TriWest Healthcare Alliance online?

TriWest users: make the switch to the Availity Portal.


TriWest and Availity have teamed up to make it easier for you to manage health care for Veterans online. The Availity Portal is now TriWest’s one-stop shop for all information and training on the Department of Veterans Affairs (VA) Community Care programs.

Providers will now use Availty to access all TriWest quick reference guides, educational materials, and Provider Handbooks. These documents will no longer be available on TriWest’s public-facing provider portal at after April 7, 2020.

TriWest’s secure portal at will remain available during the transition to Availity, but will be fully decommissioned later this year.

One password is the key to information from multiple payers.
The Availity Portal is a multi-payer site where you can use a
single user ID and password to work with TriWest and other participating payers online. Availity is compliant with all HIPAA regulations, and there is no cost for providers to register or use any of the online tools.
