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.

27158 billing questions
When should the bilateral code be selected instead of 27156?
Use 27158 when the documented pelvic osteotomy is bilateral. Code 27156 is the unilateral counterpart.
Should modifier 50 be added?
No. CMS prices 27158 as bilateral, and modifier 50 does not increase payment.
Is open reduction separately reported with this procedure?
Open reduction of the hip is included when performed as part of the pelvic osteotomy reported with 27158.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant-at-surgery claim be submitted?
Assistant-at-surgery payment may be allowed. Co-surgeon and team-surgery payment are not permitted for this code.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
