About 27181: Femoral neck osteotomy for slipped epiphysis
Reports a femoral neck osteotomy to correct deformity associated with slipped capital femoral epiphysis, rather than traction or pinning in situ.
This procedure surgically cuts the femoral neck to correct alignment in a patient with slipped capital femoral epiphysis. Orthopedic surgeons typically perform it in an operating room when the deformity calls for osteotomy rather than treatment by traction or pinning in situ. The operative report should identify the affected side, femoral neck osteotomy, the deformity being corrected, and the correction performed.
Report the code for the femoral neck osteotomy, not simply because the patient has a slipped epiphysis; documentation should support the procedure actually performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
