How to Appeal a Cigna Denial

What should I emphasize in a Cigna appeal?

Cigna denials often cite numbered medical policies. Quote the exact policy section in your appeal and attach chart notes that satisfy each criterion. Pharmacy and medical appeals use different portals, so filing through the wrong channel is a common reason strong clinical cases get delayed.

AppealFlow helps consumers draft insurer-specific appeal letters for free. This guide consolidates the portals, deadlines, and documentation patterns that most often matter for Cigna members — so you can file a complete first-level appeal instead of a generic complaint.

What Cigna plan types does this guide cover?

• Site-of-service or coding mismatch on the claim

How do I appeal a Cigna denial step by step?

1. Step 1

   Request a written denial letter from Cigna that lists the claim number, reason code, and medical policy number cited.

2. Step 2

   Confirm whether your plan is ERISA self-funded, fully insured, or Medicare Advantage, because appeal clocks and external review paths differ.

3. Step 3

   For medical claims, log in to myCigna → Claims → select the denied line → Appeal a Decision and download the EOB.

4. Step 4

   For Express Scripts pharmacy denials, have your prescriber submit a formulary exception or prior authorization through CoverMyMeds with a letter of medical necessity.

5. Step 5

   Draft an internal appeal that maps your diagnosis, treating physician notes, and guideline citations to each bullet in the cited Cigna policy.

6. Step 6

   Submit online through myCigna or by certified mail to the address on your EOB before the printed deadline; save confirmation numbers or tracking.

7. Step 7

   If the internal appeal is upheld, request a second-level review when your plan documents allow it, then external review under ACA Section 2719 for eligible non-grandfathered plans.

8. Step 8

   For urgent cases where delay could seriously jeopardize health, request an expedited appeal when filing and cite the clinical urgency in writing.

What documents do I need for a Cigna appeal?

• Cigna denial letter or EOB with claim ID, reason code, and policy reference
• Letter of medical necessity from your treating physician
• Relevant imaging, lab results, and specialty consult notes
• Prior authorization request and decision history (if applicable)
• Failed conservative treatment timeline when the denial cites step therapy or imaging criteria
• Cigna medical policy or clinical guideline excerpt the plan applied
• Peer-reviewed or society guidelines (ACR, NCCN, ADA, etc.) supporting your request
• Proof of timely submission (portal screenshot, fax confirmation, or certified-mail receipt)

What laws can I cite in a Cigna appeal?

Citing the correct framework shows reviewers you understand your rights. Exact applicability depends on whether your Cigna coverage is employer self-funded, fully insured, Medicare Advantage, or Medicaid.

• ERISA §503 (29 U.S.C. §1133): full and fair review for employer-sponsored group health plans
• ACA Section 2719 (42 U.S.C. §300gg-19): internal and external appeal rights for non-grandfathered plans
• 45 CFR §147.136: federal standards for claims and appeals procedures
• 42 CFR Part 422: Medicare Advantage organization determinations and reconsiderations

What if Cigna denies my appeal?

If your first-level Cigna appeal is upheld, review your denial letter for the next appeal level and filing deadline. Depending on your plan type, you may request a second internal review, external review by an Independent Review Organization under ACA Section 2719, a Medicare Independent Review Entity, a state fair hearing for Medicaid, or state Independent Medical Review for HMO coverage. Deadlines and available paths are printed on your adverse decision notice.
