To fax an appeal or dispute to Cigna Healthcare, use 877-815-4827, the fax for Cigna National Appeals in Chattanooga, TN. If the patient's ID card shows a "G" or "GWH-Cigna" indicator, use 877-804-1679. Appeals about pharmacy (Express Scripts) decisions go to 877-852-4070. Cigna publishes these on its official provider pages, and they serve most employer-plan appeals. If your denial letter or EOB gives a different number, use that one.

This guide covers the Cigna fax numbers we confirmed on cigna.com, which plans and requests they cover, and the details that keep an appeal from being bounced.

  • Three verified fax lines: National Appeals, "G" ID card plans, and Express Scripts clinical appeals
  • ID card first: the card tells you which appeals unit handles your plan
  • Prior authorization at Cigna runs mainly through the portal and phone, not a public fax line

Which Cigna line is yours

Cigna sends appeals to one of three places, and the member ID card tells you which:

  • Standard Cigna Healthcare plans go to Cigna National Appeals, P.O. Box 188011.
  • Cards with "GWH-Cigna" or a "G" indicator go to a separate National Appeals unit at P.O. Box 188062, with its own phone and fax.
  • Pharmacy decisions made by Express Scripts, Cigna's pharmacy benefit manager, are appealed to the Express Scripts Clinical Appeals Department.

Cigna also lists separate routes for appeals involving EviCore (for services such as imaging that EviCore reviews), and Medicare and Medicaid plans have their own processes. If your denial letter names EviCore or a Medicare plan, follow that letter.

Verified Cigna fax numbers

These numbers come from Cigna's official provider pages and forms on cigna.com. Each applies to the plan and request listed.

Notes on these numbers:

  • 877-815-4827 also appears on Cigna's California customer grievance form as the fax for Cigna HealthCare National Appeals, which supports the provider listing.
  • Medicare Advantage: the Cigna Medicare appeal form we found online was dated 2022, so we have not listed a number. Medicare members should use the fax in their Evidence of Coverage or on their denial letter.
  • Behavioral health may be handled by Evernorth Behavioral Health. Check the denial letter for the right appeals address.

The number on your letter wins

The numbers above are general lines. When Cigna sends a denial letter, EOB, or explanation of payment, the fax and mailing address on it come first. They lead to the team holding your case, and they reflect any rules specific to your state or employer plan.

If you have no letter, call the customer service number on the member ID card. For employer plans, Cigna itself asks members to start an appeal this way, and the representative can confirm the fax line for your plan.

Prior authorization and claims

Cigna does not publish a general public fax number for medical precertification. Its provider contact page lists the Cigna for Health Care Professionals portal (CignaforHCP.com) and 800-88Cigna (800-882-4462) for requesting precertification, and the customer service number on the patient's ID card. Some drug-specific and service-specific forms carry their own fax numbers, so use the fax printed on the current form you are completing.

Paper claims go to the address on the patient's ID card, according to Cigna's contact page. Most claims are filed electronically by providers.

For how to assemble a complete authorization request, see our prior authorization guide.

How to fax a Cigna appeal, step by step

  1. Check the ID card for a "G" or "GWH-Cigna" indicator and pick the matching line.
  2. Look for a fax number on the denial letter or EOB. Use the table only if there is none.
  3. Complete the right form. Providers use the Request for Health Care Provider Payment Review form and tick the box for the reason for appeal. Members can send a written appeal explaining why the decision should be reconsidered.
  4. Attach the original EOB, explanation of payment, or letter, plus documents that support overturning the decision, such as operative reports or medical records.
  5. Put the patient's name, ID number, and claim number on every page.
  6. Send within 180 calendar days of the initial payment or denial notice (or of the last payment adjustment, for provider appeals), and keep the confirmation.

No fax machine needed. You can send a fax online for $2.99, with no subscription and no account, and get the delivery confirmation by email. For records to support the appeal, see faxing medical records.

Common mistakes that delay a Cigna appeal

  • Faxing the wrong unit. A "G" card appeal sent to the main National Appeals line, or a pharmacy appeal sent to Cigna instead of Express Scripts, adds delay while it is rerouted, if it is rerouted at all.
  • No EOB or letter attached. Cigna asks for the original EOB, explanation of payment, or letter so the reviewer can see the decision being challenged.
  • An incomplete form. Cigna asks providers to fill in the payment review form fully, including the reason-for-appeal box.
  • Missing the 180-day window. Late appeals can be refused regardless of merit.
  • No page count. A cover sheet with the total page count shows whether pages went missing.

Cigna appeals go smoothly when the ID card points you to the right unit, the EOB is attached, and you keep the confirmation.
