Cigna Fax Number — Fax Claims and Prior Authorizations
Cigna takes medical claims, prior authorizations, enrollment forms, and appeals by fax, but the number you need depends on the plan and the function, so there is no single Cigna fax line. The correct number for claims, credentialing, or grievances is usually printed in your policy documents or on the form you are completing. Cigna's claims department generally operates Monday through Friday during business hours, Eastern time.

- Medical claims
- Prior authorization requests
- Enrollment and disenrollment forms
- Provider credentialing documents
- Appeals and grievances
Tip: Carry your policy number, and the claim number where one exists, onto every page so Cigna can reassemble documents that get separated in processing. For prior authorizations, attach the diagnosis code, the procedure code, and a brief clinical justification, because requests missing those are the ones that get returned. Sending through Send FAX Mail leaves you with a delivery confirmation proving the submission reached Cigna by the deadline.
