How to Fax a Prior Authorization Request to Cigna
Cigna requires prior authorization for certain medications, imaging, and procedures, and a prescriber's office can submit the request and its clinical backup by fax. This guide explains who prepares the request, which identifiers and codes make it reviewable on the first pass, how to find the fax line tied to the member's plan, and how to check where the decision stands afterward.
Does Cigna accept a fax?
Cigna accepts prior authorization requests by fax for many benefits, with the receiving line determined by the plan type and whether the request is for a drug or a medical service. Cigna often routes pharmacy reviews through its pharmacy benefit operations while medical reviews go elsewhere, so the accepting fax depends on what is being authorized.
Finding the official fax number
The current fax number appears on the Cigna prior authorization form for the specific service and on the provider portal where the request is normally initiated. The member's benefit documents and any coverage-decision letter you received also state the correct destination, so verify the number against those sources rather than a saved one, since Cigna updates lines by review team.
What to include on every page
- The patient's name, date of birth, and Cigna ID number as printed on the member card
- The requesting provider's name, NPI, and a return fax for the determination
- The exact drug name and strength, or the CPT code for the procedure, plus ICD-10 diagnoses
- Documentation of tried-and-failed therapies or clinical criteria the plan lists
- A cover page identifying the patient and stating whether the request is standard or expedited
How to fax Prior Authorization Request Form to Cigna
- 1Fill out the Cigna prior authorization form that corresponds to the requested drug or service
- 2Gather the chart notes and test results that meet Cigna's medical-necessity criteria

- 4Merge the completed form and supporting records into a single legible PDF
- 5Log in to Send FAX Mail, upload the PDF, key in the confirmed fax number, and transmit
- 6Store the delivery confirmation in the patient record as evidence of when it was filed
Confirming it arrived
After the fax lands, Send FAX Mail hands back a time-stamped receipt you can keep beside the request. Cigna returns its determination through the provider portal or by fax, and if the decision runs past the expected window you can use that receipt to show the complete packet was submitted on the date claimed.

Recent updates
Federal interoperability rules keep pushing healthcare past the fax machine
CMS has advanced a series of interoperability rules that press hospitals, payers, and providers toward electronic data exchange and standardized claims attachments. The direction of travel is clear: paper and analog fax workflows are being replaced by digital transmission that carries an auditable record — which is exactly what a cloud fax with delivery confirmation provides for offices not yet on a full EHR pipeline.
CMS →Healthcare breach reporting keeps document handling under scrutiny
Ongoing reporting on HIPAA breaches and OCR settlements underscores how much scrutiny falls on how medical documents are stored, sent, and received. Sending records through a controlled, access-logged channel rather than an unmanaged machine reduces the mishandling risks that show up repeatedly in breach analyses.
HIPAA Journal →HHS OCR continues enforcing HIPAA safeguards on how PHI is transmitted
The HHS Office for Civil Rights enforces the HIPAA Security Rule's requirement that covered entities apply administrative, physical, and technical safeguards to protected health information in transit. Faxing PHI is permitted, but the sending practice is responsible for confirming the destination and controlling access — the reason healthcare senders favor a channel that logs each transmission and its recipient.

Faxing Prior Authorization Request Form to Cigna — FAQ
In practice the prescribing or ordering provider files it, because the request has to carry clinical documentation and provider identifiers that only the office holds. A member can ask their doctor to start a Cigna prior authorization, but the reviewable packet comes from the practice, not the patient.
The most common cause is a packet missing the clinical evidence Cigna's criteria call for — no prior-therapy history, absent chart notes, or an unlisted diagnosis code. Requests are also returned when the drug name, strength, or procedure code is incomplete, so check every field against the criteria before faxing.
Include the member ID, the ordering provider's NPI, the ICD-10 diagnosis codes, and the specific drug (with strength) or CPT/HCPCS code for the service. Those data points let Cigna match the request to the member's benefit and the applicable coverage policy; leaving one blank stalls the review.
Determinations are posted back through the Cigna provider portal and typically confirmed by fax or letter to the ordering office. If nothing has arrived within the plan's stated turnaround, the practice can check portal status or call using the reference on the submitted form.
