Centene Fax Number — Fax Claims and Prior Authorizations

Centene processes claims, prior authorizations, enrollment changes, and provider credentialing through fax, but as a large managed-care company it splits these across departments and plan brands, so there is no single number that covers everything. The right fax line depends on which Centene plan and function you are dealing with, and it is usually printed in your policy documents or provider manual. The claims department generally works Monday through Friday during business hours, Eastern time.

What You Can Fax to Centene

  • Medical claims
  • Prior authorization requests
  • Enrollment and disenrollment forms
  • Provider credentialing documents
  • Appeals and grievances
Tip: List your policy number, and the claim number when you have one, on every page so Centene can match split documents back to your file. For prior authorization requests, include the diagnosis code, the procedure code, and a short clinical justification, since incomplete submissions are the most common cause of delays. Send through Send FAX Mail so you keep a delivery confirmation to show the request reached Centene on time.

Missing codes or justification. Include the diagnosis code, procedure code, and a brief clinical rationale on the fax so the reviewer has what they need on the first pass rather than sending it back for more information.
