Orthopedic surgery
About 27147: Combined pelvic and femoral osteotomy
Reports corrective hip-bone realignment that includes osteotomies of both the pelvis and femur, commonly for structural hip deformity or developmental dysplasia.
This code describes a reconstructive operation combining an osteotomy of the iliac, acetabular, or innominate bone with a femoral osteotomy to improve hip alignment or joint coverage. Orthopedic surgeons most often perform it for significant structural deformity, including selected cases of developmental hip dysplasia. The operative report should identify the pelvic and femoral work performed and the side treated; the code represents the combined procedure rather than an isolated pelvic osteotomy.
Report it when both components are performed in the same operative session. Documentation should support the deformity being corrected, the specific bones and osteotomies, and laterality. It has 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 other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be allowed; co-surgeon payment requires supporting documentation. Team surgery is not permitted.

27147 billing questions
When should I choose this instead of 27146?
Use 27147 when the operation includes both a pelvic osteotomy and a femoral osteotomy. Code 27146 describes the pelvic osteotomy without the femoral osteotomy.
Can the femoral osteotomy be billed separately?
The combined procedure is represented by 27147 when the pelvic and femoral osteotomies are performed together as the described reconstruction. The operative report should make both components clear.
What documentation supports reporting this code?
Document the hip deformity or other indication, the pelvic and femoral bones treated, the osteotomies performed, and the side. The operative report should establish that both bony components were part of the reconstruction.
How is bilateral reporting handled?
CMS lists bilateral reporting with modifier 50, paid at 150%. The documentation should support the procedure on both sides.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
May an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be allowed. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
