Steps

  1. Call customer service. Ask for the reason, the plan provision and how to appeal. Cigna says it tries to resolve complaints on the first contact.

    PhoneCigna Healthcare customer service +1-800-997-1654
  2. If someone else will appeal for you, complete the appointment of representative form.

  3. Complete the medical appeal request form and send it with records to the address on the denial letter, within the deadline on that letter.

  4. After the final internal denial, use the external review forms on the forms page (state forms apply in some states), or contact your state insurance department.

  5. For an employer self-funded plan, contact the Department of Labor if the plan does not follow the claims rules.
