Confirm your beneficiary’s TRICARE plan before determining coverage or starting treatment. A Uniformed Services ID card does not show plan type, so verify eligibility through the provider portal, Availity. This ensures you know whether the patient is enrolled in TRICARE Prime, TRICARE Select, or a specialty plan, and what referral, authorization, or cost‑sharing requirements apply.

How to Verify Coverage

  • Log in to the provider portal, Availity.
  • From the top navigation menu, select Patient Registration.
  • Open the Eligibility and Benefits Inquiry application.
  • Select the TRIWEST - TRICARE payer.
  • Enter the required patient information.
  • For TRICARE inquiries, the Member ID must be one of the following without dashes or spaces:
    • the patient’s nine-digit Social Security Number (SSN)
    • the patient’s 11-digit DEERS Beneficiary Number (DBN)
  • Submit the inquiry to view the patient’s eligibility and benefit details.
