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.

What You Can Fax to Cigna

  • 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.

Faxing to Cigna — FAQ

Cigna splits claims, authorizations, appeals, and credentialing across departments with different fax numbers. Check your policy documents or the specific form for the line that matches your plan and request rather than assuming one number works for all.

Fax the claim documentation with your policy number and claim number printed on every page. Using Send FAX Mail gives you a delivery confirmation that works as proof of submission if a timing dispute comes up later.

Standard health insurance claims are usually processed within about 30 days. Prior authorizations move faster when urgent, often within 24 to 72 hours depending on the medical circumstances.

Completeness. Include the diagnosis code, procedure code, and a short clinical justification on the fax so the reviewer can decide without requesting more documentation and adding days to the wait.
