How to Appeal a Cigna Prior Authorization Denial (2026 Step-by-Step Guide)

Why Cigna Denies (And Why You Can Usually Win)

Cigna denies roughly 18-22% of prior authorization requests on first submission. Of those denials, fewer than 12% are ever appealed — but when clinicians do appeal with properly structured documentation, success rates exceed 55%. The gap between first-pass denial and appeal overturn is almost entirely documentation quality.

Cigna uses Coverage Policy documents (numbered and publicly available at cigna.com/health-care-providers/coverage-and-claims/clinical-policies) to spell out medical necessity criteria. Any appeal that cites the exact Coverage Policy number and addresses each criterion one by one wins significantly more often than a generic clinical letter.

Cigna Appeal Levels and Timelines

Cigna has three formal appeal levels for commercial members:

• ✓ Level 1 (Reconsideration): 180 days from denial to file; Cigna responds in 30 days standard, 72 hours urgent
• ✓ Level 2 (Second-level appeal): 60 days from Level 1 denial; same response timelines
• ✓ Level 3 (External Review): 60 days from Level 2 denial; independent external review organization decides

The 5-Step Cigna Appeal Framework

Every Cigna appeal that wins shares the same structure.

• ✓ Step 1: Pull the denial letter and identify the exact reason code and Coverage Policy number
• ✓ Step 2: Download that Coverage Policy PDF from cigna.com and map each criterion to your chart
• ✓ Step 3: Document step therapy with dates, doses, and discontinuation reasons for every prior agent
• ✓ Step 4: Cite 1-2 recent guideline recommendations (e.g., ACR, NCCN, ADA) by recommendation number
• ✓ Step 5: Close with a specific clinical request (drug, dose, frequency, duration) and prescriber attestation

Common Cigna Denial Reasons and Winning Responses

"Step therapy not met" is the most common denial. Winning response: list every prior agent with start date, end date, daily dose, and specific reason for discontinuation (e.g., "Methotrexate 20mg weekly 03/2024–08/2024, d/c due to AST 98 / ALT 115").

"Not medically necessary" usually means Cigna thinks the criteria in the Coverage Policy aren't met. Winning response: Copy each criterion from the Coverage Policy and paste your patient's documentation underneath each one.

"Non-formulary" means the drug isn't on Cigna's formulary tier. Winning response: submit a formulary exception request with clinical justification for why every formulary alternative is inappropriate for this patient.

When to Request a Peer-to-Peer

Peer-to-peer conversations with a Cigna medical director convert 55-65% of the time when the clinician is prepared. Always request a P2P when: (1) the denial cites "not medically necessary" but your chart clearly meets policy, (2) step therapy requirements are ambiguous, or (3) the patient has an unusual clinical profile that doesn't fit standard criteria. Call 1-800-882-4462 to request a P2P.

Urgent / Expedited Appeals

If a denial is causing imminent harm, request expedited processing. Cigna must respond within 72 hours. Urgent appeals apply when standard timelines would jeopardize the patient's life, health, or ability to regain maximum function. Most specialty drug appeals qualify — when in doubt, request expedited.
