CPT code 27286 represents an orthopedic surgical procedure that immobilizes the hip joint using fixation devices, incorporates autologous bone grafting to induce bone formation, and includes a subtrochanteric osteotomy of the femur. This code captures complex reconstructive work on the proximal femur and hip joint and is used in cases requiring stabilization and realignment with bone grafting.

The analysis covers national payer practices including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context on the procedure type and typical sites of service, plus operational benchmarks and policy considerations relevant to billing and coverage for complex hip reconstruction. Key topics include typical utilization settings (inpatient and ambulatory surgical centers), common documentation elements needed to support medical necessity, and how payers approach coverage of combined fixation, grafting, and osteotomy procedures.

This publication provides clinicians, coding staff, and policy analysts a concise reference for understanding what CPT code 27286 represents, why it matters for reimbursement and care pathways nationally, and where to focus clinical documentation and prior authorization efforts. Data not available in the input are explicitly noted in the detailed sections.
