Cigna's confirmed fax number, 1-866-873-8279, is for provider precertification and prior authorization requests.
Cigna pushes most member claims and much of its prior authorization volume through electronic channels like CoverMyMeds, fax remains a secondary option.
No general consumer claims fax is published, members should use the Cigna member portal or the number on their ID card.
