Information about TriWest/TRICARE for Asuris Providers

Share your email address with TriWest using one of the following options:

TriWest Healthcare Alliance (TriWest) is contracted with the U.S. Department of Defense for the administration of the TRICARE program in the West Region. The TRICARE program is a health entitlement program for active duty and retired members of the military as well as their eligible dependents.  TriWest is an alliance of shareholder companies, including Regence and other BlueCross and BlueShield Plans and two large university health systems.  TriWest subcontracts panel development and maintenance activities to TriWest shareholder companies, including Regence. Asuris is also responsible for assisting and training network providers.

There are three TRICARE options available for eligible beneficiaries: Standard, Extra, and Prime.

  • TRICARE Standard is similar to a traditional indemnity plan with cost sharing and an annual deductible
  • TRICARE Extra is similar to a preferred provider organization (PPO)
  • TRICARE Prime is similar to a health maintenance organization (HMO)

For benefit information, please call 1 (888) TRIWEST (874-9378).

Claims, billing and reimbursement
Hospitals are reimbursed according to TRICARE’s diagnosis-related group (DRG) based payment methodology and Medicare guidelines with the exception of sole community hospitals which are reimbursed based on billed charges. Physicians and ancillary providers are paid according to a fee schedule called Champus Maximum Allowable Charge (CMAC).

TriWest has partnered with Wisconsin Physicians Service Insurance Corporation (WPS) to process and pay claims.
