Summary & Overview
CPT 22808: Anterior Spinal Fusion, 2–3 Segments
CPT code 22808 represents an anterior spinal arthrodesis (spinal fusion) of two to three contiguous vertebral segments. This operative code captures a common reconstructive and stabilizing spine surgery used to address deformity and persistent pain from conditions such as scoliosis and kyphosis. Nationally, spinal fusion procedures are significant drivers of surgical utilization and inpatient surgical resource use due to their complexity and perioperative needs.
Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what 22808 represents clinically, the typical sites of service, and the payer landscape covered. The publication outlines reimbursement and utilization benchmarks where available, common billing and coding considerations, and relevant policy or coverage themes that affect claims adjudication and prior authorization practices.
The piece provides clinical context for when an anterior 2–3 level fusion is coded, highlights typical postoperative care settings, and clarifies the code’s role within spinal surgery coding sets. Data not available in the input will be noted where applicable, and the reader will gain an operational summary useful for coding staff, billing managers, and policy analysts working with spinal surgery claims.
Billing Code Overview
CPT code 22808 describes an arthrodesis (spinal fusion) procedure performed via an anterior (front) approach to the spine, fusing two to three vertebral segments. The procedure secures adjacent vertebrae to reduce motion at a painful unstable segment and to treat spinal deformities such as scoliosis or kyphosis. The description notes the provider may apply a body cast as part of postoperative immobilization.
Service type: Surgical – spinal fusion (anterior approach), 2–3 segments
Typical site of service: Hospital operating room or ambulatory surgical center with inpatient admission possible depending on clinical need
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with progressive thoracolumbar deformity and chronic axial back pain presents for evaluation after conservative care failed. Imaging shows degenerative disc disease with coronal and sagittal imbalance involving two adjacent motion segments in the anterior column. The spine surgeon plans an anterior spinal arthrodesis (fusion) of two to three vertebral segments using interbody structural graft and anterior plating. The procedure is scheduled in an operating room with general anesthesia, preoperative antibiotics, and intraoperative fluoroscopic guidance. Postoperative care includes monitoring in the PACU, pain control, early mobilization with a possible thoracolumbosacral orthosis or body cast applied postoperatively, and routine wound checks. Typical sites of service are an inpatient hospital operating room or an ambulatory surgery center for select patients. Billing uses 22808 for arthrodesis, anterior approach, two to three vertebral segments fused.
