Summary & Overview
CPT 22802: Multilevel Spinal Fusion, 7–12 Vertebral Segments
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.
Billing Code Overview
CPT code 22802 describes arthrodesis (spinal fusion) performed to secure multiple vertebral segments. The procedure is used to treat persistent pain and structural deformities of the spine, such as scoliosis or kyphosis, by fusing vertebrae together to eliminate motion at painful segments. The description specifies fusion of seven to twelve vertebral segments and notes that the provider may apply a body cast as part of postoperative management.
Service type: Major spinal surgery — multilevel posterior/anterior spinal fusion (arthrodesis).
Typical site of service: Inpatient hospital or specialized surgical center for operative spinal fusion and immediate postoperative care.
Clinical & Coding Specifications
Clinical Context
A 62-year-old patient with progressive thoracolumbar deformity and chronic mechanical back pain presents for planned multilevel posterior spinal arthrodesis. Prior conservative care including physical therapy, epidural injections, and analgesics failed to relieve symptoms. Imaging demonstrates degenerative scoliosis with instability across multiple motion segments spanning T10 to L5 (nine vertebral segments). The surgical team schedules an elective posterior spinal fusion with instrumentation and possible application of a body cast for postoperative immobilization.
The clinical workflow includes preoperative evaluation by the spine surgeon and anesthesia team, imaging review and surgical planning, informed consent addressing risks and anticipated levels fused, perioperative administration of prophylactic antibiotics, intraoperative neuromonitoring and instrumentation placement across seven to twelve segments, grafting and arthrodesis techniques, potential application of a body cast, and postoperative inpatient monitoring with pain control, mobilization, and discharge planning to home or rehabilitation based on recovery.
