TRICARE Fax Number — Claims, Authorizations, and Enrollment

TRICARE, the health program for uniformed service members, retirees, and their families, is administered by regional contractors rather than a single office, so the fax you need depends on your region and the type of request. A prior-authorization or referral goes to the fax line the regional contractor publishes for authorizations, while claims and enrollment forms go to their respective intake teams. Beneficiaries and providers find the current fax lines on the regional contractor's website and on the forms themselves, and the back of the beneficiary card lists customer-service contacts. Because TRICARE East and West are run by different contractors, match the fax line to your region before sending.

What You Can Fax to TRICARE

  • Prior-authorization and referral requests
  • Claim forms and supporting documentation
  • Enrollment and plan-change forms
  • Other-health-insurance and coordination-of-benefits forms
  • Medical records requested to support a claim or authorization
Tip: TRICARE faxes about a beneficiary contain protected health information, so send them through a HIPAA-eligible service and label every page with the sponsor's identifier, the beneficiary's name, and date of birth in case pages separate. Send FAX Mail's HIPAA-eligible Business plan ($79.99/month) works for this and returns a transmission receipt you can keep as proof a claim or authorization reached the contractor before its deadline. Note your TRICARE region and the request type on the cover sheet so the fax reaches the correct intake team.

Faxing to TRICARE — FAQ

No. TRICARE is administered by separate regional contractors, and each publishes its own fax lines for claims and authorizations. Identify your region first, then use the fax line the contractor lists for the specific request type.

The authorization fax line appears on your regional contractor's website and in the instructions on the authorization or referral form itself. Because contractors and their contact points can change between contract periods, verify the current number before sending.

Complete the claim form for your plan and fax it, with itemized bills or records, to the claims fax line your regional contractor publishes. Include the sponsor's identifier on every page and keep the transmission receipt as evidence of the filing date.

Enrollment and plan-change requests are handled by the regional contractor and may be accepted by fax, online, or mail depending on the form. Check the current enrollment instructions for your region to confirm the accepted channel and destination before faxing.
