What 27151 covers

An orthopedic surgeon cuts and repositions pelvic bone to improve hip alignment or coverage. A bilateral pelvic osteotomy may be performed for congenital hip dysplasia or another documented pelvic deformity. The operation takes place in a surgical setting; the operative report should identify the bones treated and the correction performed on each side.

Select this code for the bilateral pelvic osteotomy described by the operative work, distinguishing it from a more localized iliac or acetabular osteotomy and from procedures that reposition the femoral head. Documentation should establish the indication, laterality, operative steps, and any separately performed procedures. CMS assigns a 90-day global period, including 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 others at 50%. The bilateral rule with modifier 50 is payment at 150%. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

27151 billing questions

How does 27151 differ from 27146?

27151 describes a bilateral pelvic osteotomy. Code 27146 is for an osteotomy of the iliac, acetabular, or innominate bone, so select based on the documented site and procedure.

When would 27147 be considered instead?

27147 describes an iliac, acetabular, or innominate osteotomy with femoral head repositioning. The operative report should support that repositioning and the specified bone work.

What postoperative care is included?

The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

How does Medicare handle bilateral payment?

CMS lists bilateral payment with modifier 50 at 150%. Code 27151 itself describes bilateral pelvic osteotomy, so the documentation should support the bilateral work reported.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery services may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

What happens when another procedure is performed in the same session?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
