Summary & Overview
CPT 27280: Open Sacroiliac Joint Fusion with Autograft and Instrumentation
CPT code 27280 represents an open sacroiliac joint fusion procedure that uses autologous bone grafting and may include internal fixation. This code captures a definitive surgical approach for patients with sacroiliac joint pain or instability and is relevant for national surgical practice patterns, payer coverage decisions, and hospital service-line planning. Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical intent and typical care setting for the procedure; a summary of which payers are addressed; and what to expect in benchmarking and policy review sections, including common billing considerations and documentation elements relevant to coverage determinations. The publication highlights clinical context around indications for fusion, typical perioperative setting, and elements that influence coding and reimbursement. Data not available in the input for associated taxonomies, ICD-10 diagnoses, and related codes will be noted where applicable in detailed sections. This material is written for a national audience interested in coding accuracy, payer policy alignment, and operational implications for surgical services involving sacroiliac joint arthrodesis.
Billing Code Overview
CPT code 27280 describes an open surgical procedure to immobilize the sacroiliac joint by inducing bone formation across the joint, commonly called sacroiliac joint arthrodesis with bone grafting. The code specifically includes harvest of autologous bone graft from the patient and the use of instrumentation when performed.
Service type: Surgical — open sacroiliac joint fusion with autograft and possible instrumentation.
Typical site of service: Inpatient or outpatient hospital operating room or ambulatory surgery center, depending on clinical complexity and payer rules.
Clinical & Coding Specifications
Clinical Context
A 52-year-old ambulatory patient with chronic, refractory sacroiliac joint pain related to degenerative sacroiliitis and prior failed conservative treatment (physical therapy, corticosteroid injections, and analgesics) is scheduled for surgical sacroiliac joint arthrodesis via an open approach. The patient presents preoperatively for evaluation, imaging review, and informed consent. On the day of surgery the patient undergoes general anesthesia, a posterior or lateral open incision over the sacroiliac joint, debridement of the joint surfaces, autologous bone graft harvest (typically from the posterior iliac crest), placement of bone graft into the joint to promote arthrodesis, and fixation with instrumentation as indicated. Intraoperative fluoroscopy or radiographs confirm graft and hardware position. The patient receives perioperative antibiotics and postoperative pain management, is observed in a post-anesthesia care unit, and is admitted for short-term inpatient recovery with mobility precautions and a tailored rehabilitation plan focused on protected weight bearing and gradual return to function.
