CPT code 22802 represents multilevel spinal arthrodesis (spinal fusion) performed to secure seven to twelve vertebral segments, commonly used to treat persistent pain and structural deformities such as scoliosis and kyphosis. This major surgical procedure is nationally significant because it involves extensive operative time, resource use, and postoperative care, and it has implications for hospital reimbursement, utilization management, and clinical pathways for complex spine disease. Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find a concise briefing on the clinical context of multilevel spinal fusion, typical sites of service, and the kinds of benchmarks and policy considerations that affect coverage and billing for large-segment arthrodesis. The publication covers utilization benchmarks, common payer authorization and coverage themes, relevant documentation and coding considerations, and recent policy updates that influence prior authorization and medical necessity review for major spine surgery. Data not available in the input for specific payer rates, ICD-10 pairings, and associated taxonomies are noted where applicable.
