Summary
TRICARE has updated its policy outlining how patients should update their personal information in DEERS and with regional contractors. This is primarily a patient-facing resource that provides contact information and procedures for updating demographics, but billing teams should be aware of the updated contact numbers for coordination purposes.
Action Required
Update office contact lists with current TRICARE contractor phone numbers: East Region (Humana Military: 800-444-5445), West Region (TriWest: 888-874-9378), and DEERS support (800-538-9552). Ensure front desk staff are aware of these resources when patients need to update their information for eligibility verification.
