About 27158: Bilateral pelvic osteotomy for hip correction
Reports bilateral pelvic osteotomy to correct hip alignment, such as for congenital hip dislocation, with open reduction included when performed.
An orthopedic surgeon performs this bilateral pelvic osteotomy to reposition or reshape the pelvis as part of correcting hip alignment, commonly for congenital hip dislocation or developmental hip dysplasia. The operation is performed in the operating room; open reduction of the hip is included when performed as part of the procedure. This code identifies the bilateral pelvic service, rather than a femoral osteotomy or hip replacement.
Select the code from the operative report’s documented procedure and laterality, including the pelvic bone work and whether open reduction was performed. CMS prices this code as bilateral, so modifier 50 does not increase payment. It has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Assistant-at-surgery payment may be allowed; co-surgeon and team-surgery payment are not permitted.
