Welcome to TRICARE West

Your access to care is our priority. Please review the "Five Things to Know" for beneficiaries and providers.

The answers to your questions might be found on our website. We offer public and secure tools (log in required) to help you with your TRICARE transactions, including cost pages that explain the new copayment structure. 

You can also use our Interactive Voice Response system for certain transactions, such as checking eligibility and making enrollment payments, rather than waiting on hold. Tip: If you have background noise when using the IVR, mute your phone and key in your responses.
