This guide explains why Cigna denies surgery and gives you a clear path to appeal.

Why Cigna Denies Surgery Claims

Cigna evaluates surgical claims using its Medical Coverage Policies — publicly available clinical criteria documents that define what Cigna considers medically necessary for specific procedures. These policies are accessible at cigna.com/coverage-policies. Common denial reasons include:

• No prior authorization: Cigna requires prior authorization for most elective and semi-elective surgeries. Authorization must be obtained by your provider through Cigna's provider portal (cignaforhcp.com) or by calling Cigna's clinical team at 1-800-88CIGNA (1-800-882-4462). Without a valid authorization, the claim will be denied.
• Medical necessity criteria not met: Cigna's Coverage Policies establish specific criteria for each surgical procedure. For example, lumbar spinal fusion typically requires documented failure of at least 6 months of nonsurgical care, specific imaging findings, and documented functional disability. If your records don't satisfy all criteria, Cigna will deny the claim.
• Out-of-network provider or facility: If your surgeon or the hospital is not in Cigna's network, claims may be denied or significantly underpaid. Cigna's networks include Open Access (OA) plans with out-of-network coverage and HMO plans with strict network limits.
• Procedure classified as experimental or investigational: Cigna's Medical Coverage Policies categorize many newer surgical techniques as investigational and exclude them from coverage.
• Step therapy or conservative care not documented: Cigna routinely requires evidence that less invasive treatments were tried and failed before surgery.
