How to Appeal a Cigna Denial — Complete 2026 Guide + Free Template
Cigna covers approximately 20 million Americans across individual, employer, Medicare, and international plans. A subsidiary of The Cigna Group (now operating under the Evernorth brand for health services), Cigna is known for aggressive prior authorization requirements and a high rate of step therapy denials. What distinguishes Cigna appeals is their publicly accessible Coverage Policies — detailed documents that define exactly what clinical criteria must be met for coverage — and a dedicated Cigna Appeals Center that handles the formal review process. This guide shows you how to use both to your advantage.

Cigna Coverage Policies — Your Strategic Tool
Cigna publishes its coverage criteria as Coverage Policies — internal documents that define exactly what clinical criteria a treatment must meet before Cigna will approve it. Like Aetna’s Clinical Policy Bulletins and UHC’s Coverage Determination Guidelines, these policies are the rulebook Cigna reviewers apply when evaluating claims.
How to find the Cigna Coverage Policy applied to your denial
- Read your denial letter — it should reference a specific Coverage Policy name or number (e.g., “PHARM_1234” for pharmacy or “MED_5678” for medical procedures)
- If not listed, call Cigna Customer Service at the number on your member ID card and ask which Coverage Policy was applied to your denial
- Request your complete claim file — federal law requires Cigna to provide this free of charge within 30 days, including the policy and reviewer notes
- Search for the policy at cigna.com — look under “For Health Care Professionals” → “Coverage Policies” or search the policy number directly
- Read the “Coverage Criteria” or “Indications” section — this is the checklist your appeal must satisfy point by point
Quote each Coverage Policy criterion in your appeal letter, then present the specific clinical evidence from your medical record that satisfies it. Cigna reviewers evaluate appeals against the policy — a letter that addresses every criterion with documented evidence is far more effective than a generic medical necessity statement. This is the single highest-impact thing you can do in a Cigna appeal.
The Cigna Appeals Center Process
Cigna routes all formal member appeals through its dedicated Appeals Center. Understanding how the Appeals Center works — and the two levels of review available — helps you plan your strategy before filing.
Level 1 — Standard internal appeal
Your written appeal is reviewed by a Cigna medical professional with appropriate clinical expertise who was not involved in the original denial. This is where the majority of successful appeals are resolved. Your Level 1 letter should be complete and contain all your clinical evidence — don’t hold back evidence for Level 2.
Level 2 — Voluntary additional review
If your Level 1 appeal is denied, Cigna offers a voluntary Level 2 appeal — a second internal review by a different clinical panel. While not required before requesting external review, Level 2 is worth pursuing if you have new clinical evidence not included in Level 1, or if you can now provide a peer-to-peer review that wasn’t available earlier.
Put your complete case into your Level 1 appeal. External reviewers assess the full appeal record — a weak Level 1 undermines your credibility at external review even if you supplement at Level 2. The strongest appeals are comprehensive from the first submission.
Cigna Appeal Deadlines — 2026
| Appeal Type | Your Filing Deadline | Cigna Response Time |
|---|---|---|
| Level 1 internal appeal (standard) | 180 days from denial notice (ACA minimum) | 30 days (pre-service) / 60 days (post-service) |
| Level 1 internal appeal (urgent) | Any time while urgent need exists | 72 hours |
| Level 2 voluntary appeal | 60 days from Level 1 denial notice | 30 days (standard) / 72 hours (urgent) |
| Concurrent care (ongoing treatment) | Sufficient advance notice before termination | 72 hours (urgent) |
| External review request | 4 months after final internal appeal denial | 45–60 days |
| Cigna Medicare Advantage | 60 days from denial notice | 30 days (standard) / 72 hours (urgent) |
| ERISA employer plan | Check Summary Plan Description — may differ | 60 days (standard) |
If your Cigna plan is a Medicare Advantage plan, your appeal deadline is only 60 days from the denial notice — not 180 days. Act immediately. See the full appeal deadlines guide for all plan-type deadlines.
Most Common Cigna Denial Reasons
| Denial Reason | What Cigna Is Claiming | Winning Rebuttal Strategy |
|---|---|---|
| Not medically necessary — Coverage Policy criteria not met | Your treatment doesn’t satisfy the applicable Cigna Coverage Policy — often determined algorithmically | Find the specific Coverage Policy. Address each unmet criterion point by point with documented clinical evidence. Show your presentation satisfies every requirement. See full medical necessity guide. |
| Prior authorization not obtained | The service required pre-approval that wasn’t obtained before treatment | Argue retroactive authorization based on medical necessity. Demonstrate all Coverage Policy criteria were met regardless of the procedural oversight. See full prior auth guide. |
| Step therapy / fail-first not satisfied | Cigna requires documented failure of specified alternatives before approving the requested treatment | Document every step therapy treatment with specific dates, dosages, duration, and clinical failure reason. If step therapy completion would cause clinical harm, document that explicitly with your physician’s signed statement. |
| Experimental / investigational | Cigna classifies the treatment as not established standard of care under its Coverage Policy | Establish FDA approval status and indication. Reference professional society guidelines (NCCN, ADA, ACC, AAD, etc.) endorsing treatment as standard of care. Cite Coverage Policy’s own clinical references where they support approval. |
| Out-of-network provider | Your provider was not in Cigna’s network | Document absence of qualified in-network alternatives. Cite ACA emergency care protections if applicable. For ongoing treatment, argue continuity of care and clinical harm from mid-treatment provider change. |
| Quantity / frequency limit exceeded | The amount or frequency of the service exceeds Cigna’s plan limits | Request the specific plan language establishing the limit. Document the medical necessity for the additional quantity or frequency with objective clinical evidence. Cite Coverage Policy criteria supporting higher utilization for your diagnosis severity. |
| Benefit exclusion | Cigna claims the service is excluded under your plan | Request the exact plan exclusion language cited. Review for ambiguity. Check whether ACA mental health parity, preventive mandates, or other federal requirements override the exclusion. |
The Exact Cigna Appeal Process — Step by Step
Requesting Peer-to-Peer Review with Cigna
Peer-to-peer review is particularly effective against Cigna’s algorithmic denial process. Cigna relies heavily on automated prior authorization systems — a peer-to-peer forces a Cigna medical director to engage with your case directly, replacing the algorithm with a clinical conversation.
How to request a peer-to-peer with Cigna
- Your treating physician (not you) initiates the peer-to-peer by calling Cigna’s Provider Services line — found on the denial letter or member ID card — or through the Cigna provider portal at cignaforhcp.com
- State your explicit request in your written appeal letter: “I request that Cigna arrange a peer-to-peer review between your reviewing physician and my treating physician, [DR. NAME], prior to issuing a Level 1 appeal decision”
- Provide your physician’s name, specialty, phone number, and availability in your appeal letter
- Peer-to-peer reviews at Cigna are typically arranged within 3–7 business days of the request
Before the peer-to-peer call, share the specific Cigna Coverage Policy with your physician and highlight the criteria your clinical presentation meets. A physician who can speak criterion by criterion against the Coverage Policy has a significant advantage. Ask them specifically to document the peer-to-peer conversation in your medical record immediately after — this creates a formal record that strengthens any subsequent Level 2 or external review.

Example 1: Humira for Psoriatic Arthritis — Step Therapy Denial
Denial reason: “Prior authorization denied — step therapy requirements not satisfied per Coverage Policy PHARM_0892; conventional DMARDs not documented”
What the Coverage Policy required: Documented 3-month trial of at least two conventional DMARDs (methotrexate, sulfasalazine, or leflunomide) with inadequate response before approving a biologic.
Appeal strategy: Located Coverage Policy PHARM_0892 on cigna.com. Documented: methotrexate 20mg weekly for 5 months (discontinued due to hepatotoxicity — liver enzymes 3x upper limit, documented in labs); leflunomide 20mg daily for 4 months (inadequate response — DAS28 score 5.8 at month 4 vs 5.6 at baseline). Cited ACR guidelines recommending biologic therapy for moderate-to-severe PsA after DMARD failure. Physician letter directly referenced PHARM_0892 and confirmed both required DMARD trials were complete with documented failure.
Result: Cigna approved at Level 1 without requiring peer-to-peer review. The step therapy documentation directly satisfied each Coverage Policy criterion. The original denial was an administrative issue — the DMARD trials existed but weren’t organized against the policy criteria in the original PA request.
Example 2: Outpatient Intensive Behavioral Health — Medical Necessity Denial
Denial reason: “Not medically necessary — symptoms do not meet criteria for intensive outpatient program per Coverage Policy BEH_0234; standard outpatient therapy appropriate”
What the Coverage Policy required: Documentation that standard outpatient therapy had been tried and was insufficient, plus objective evidence of symptom severity meeting specified clinical thresholds (PHQ-9 score ≥ 15, GAD-7 ≥ 10, or documented functional impairment).
Appeal strategy: PHQ-9 score was 18 at intake (documented in records) and GAD-7 was 14 — both above policy thresholds. Standard outpatient therapy: 16 weekly sessions over 4 months with documented minimal improvement (PHQ-9 improved from 19 to 17 — below the 5-point response threshold). Cited APA and SAMHSA guidelines recommending IOP for patients with moderate-to-severe depression failing standard outpatient therapy. Invoked ACA Mental Health Parity Act — Cigna’s criteria for IOP were more restrictive than comparable medical/surgical benefit criteria, a potential parity violation.
Result: Approved at Level 1. The Mental Health Parity argument in particular prompted immediate review escalation within Cigna’s appeals process.
If Cigna Denies Your Appeal
If Cigna upholds the denial at Level 1 — and Level 2 if you file it — two powerful options remain.
External review
After exhausting Cigna’s internal appeal process, you have 4 months to request external review by an Independent Review Organization with no affiliation to Cigna. The IRO’s decision is legally binding on Cigna — if they rule in your favor, Cigna must cover the treatment regardless of their internal decision. External review is free to patients and overturns insurer decisions in approximately 40–60% of cases.
Request external review by submitting a written request to Cigna’s Appeals Center within 4 months of your final internal denial. Cigna will assign your case to a state-certified IRO. Submit any additional clinical documentation directly to the IRO before their review closes.
Mental Health Parity Act complaints
If your Cigna denial involves behavioral health, substance use treatment, or mental health services, Cigna’s criteria may be more restrictive than comparable medical/surgical benefits — a violation of the federal Mental Health Parity and Addiction Equity Act (MHPAEA). Parity violations can be reported to the Department of Labor (for ERISA plans) or your state insurance commissioner. Raising the parity argument explicitly in your appeal letter often prompts faster resolution.
