Cigna Denied Your Weight Loss Surgery? Here's How to Fight Back

Bariatric surgery — including gastric bypass, sleeve gastrectomy, and adjustable gastric banding — can be life-changing for people with severe obesity. But Cigna denies a significant number of weight loss surgery claims, citing strict eligibility criteria that vary widely based on your specific employer plan. If your claim was denied, you are not out of options.

Why Cigna Denies Bariatric Surgery

Cigna's medical coverage policy for bariatric surgery (Policy OAC-M1062) establishes a set of clinical criteria that members must satisfy before approval is granted. Common denial reasons include:

BMI threshold not met. Cigna's standard criteria require a BMI of 40 or greater, or a BMI of 35 or greater with at least one obesity-related comorbidity such as type 2 diabetes, hypertension, or obstructive sleep apnea. If your BMI falls slightly below the threshold or your comorbidities are not adequately documented, Cigna may deny coverage.

Supervised diet program incomplete. Cigna typically requires documentation of a physician-supervised weight loss program lasting three to six months within the two years prior to surgery. If your diet program was self-directed, completed more than two years ago, or not documented in your medical records, Cigna will use this as grounds for denial.

Psychiatric evaluation not completed. Cigna requires a psychological evaluation by a licensed mental health professional to assess behavioral readiness for surgery. A missing or unfavorable evaluation is a frequent denial trigger.

Employer plan exclusion. This is a critical and often overlooked issue. Cigna serves as a third-party administrator for many self-funded employer plans under ERISA. These employers set their own plan terms, and some explicitly exclude bariatric surgery regardless of medical necessity. Before investing time in an appeal, request your Summary Plan Description to confirm whether bariatric coverage exists in your plan at all.

The Role of eviCore in Cigna PA Reviews

Cigna routes many Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization decisions for bariatric surgery through its clinical subsidiary eviCore healthcare. If eviCore issued a denial on Cigna's behalf, the appeal process still runs through Cigna, but your peer-to-peer review request will be handled by an eviCore medical director. You can initiate a peer-to-peer review by calling 1-800-88-CIGNA (1-800-882-4462) and asking to be connected with the appropriate clinical reviewer.

How to Appeal a Cigna Bariatric Surgery Denial

Step 1: Request the full denial letter and clinical criteria. Cigna is required to tell you exactly which criteria you failed to meet and which medical policy governed the decision. This document is your roadmap for the appeal.

Step 2: Gather supporting clinical documentation. Work with your bariatric surgeon and primary care physician to compile:

• A detailed letter of medical necessity explaining why surgery is appropriate and conservative treatments have failed
• Records from your supervised diet program with dates and clinical notes
• Documentation of all obesity-related comorbidities with diagnostic codes
• Results of your psychological evaluation
• Any relevant labs, sleep studies, or cardiology clearances

Step 3: Address every criterion Cigna cited. Your appeal letter must respond point by point to the denial rationale. If Cigna said your supervised diet was too short, provide evidence it met the required duration. If a comorbidity was not recognized, have your physician submit a supplemental letter with supporting clinical data.

Step 4: Request a peer-to-peer review. Before filing a formal written appeal, your bariatric surgeon can request a direct physician-to-physician call with the Cigna or eviCore reviewer who issued the denial. This conversation frequently resolves straightforward documentation gaps without a full appeal.

Step 5: File a Level 1 internal appeal. You have 180 days from the denial date to file a written internal appeal. Submit to: Cigna Appeals, PO Box 188011, Chattanooga, TN 37422. Keep copies of everything and send via certified mail.

Step 6: Request an external independent review. If Cigna upholds the denial at Level 1 (and Level 2 if applicable), you have the right to an external review by an IROs) Explained" class="auto-link">Independent Review Organization (IRO). The IRO's decision is binding on Cigna. State-regulated plans have access to state IRO programs; ERISA plans use a federally approved IRO process.

What Makes a Strong Bariatric Appeal

The most successful appeals combine strong physician advocacy with thorough clinical evidence. A compelling letter of medical necessity from your bariatric surgeon should cite peer-reviewed literature supporting surgery for your specific BMI and comorbidity profile. The American Society for Metabolic and Bariatric Surgery (ASMBS) publishes clinical guidelines that directly counter many of the conservative treatment standards Cigna relies on.

If your plan explicitly excludes bariatric surgery, an appeal is unlikely to succeed on medical necessity grounds alone. In that case, consider filing a complaint with your state's Department of Insurance (for fully insured plans) or the DOL's Employee Benefits Security Administration (for ERISA plans), particularly if you believe the exclusion discriminates based on a covered health condition.
