UnitedHealthcare Fax Number — Fax Claims and Prior Authorizations
UnitedHealthcare separates its fax intake by function, so claims, prior authorizations, enrollment forms, and provider credentialing each go to their own number rather than a shared line. Appeals and grievances are handled by yet another unit. The correct number usually appears on your member ID materials, the plan's provider portal, or the specific authorization form you are completing, so check there before sending.

Tip: Include your policy number and, where a claim already exists, the claim number on every page so UnitedHealthcare can match the fax to the right record. For a prior authorization, add the diagnosis code, procedure code, and the clinical justification supporting the request, since incomplete authorizations are the usual cause of delay. Send FAX Mail returns a delivery confirmation you can keep as proof the submission went through.
