Orthopedic surgery
About 27161: Femoral neck corrective osteotomy
Reports a corrective bone cut through the femoral neck, typically performed by an orthopedic surgeon to address a proximal femur deformity.
The surgeon cuts through the femoral neck to change its alignment or shape, most often to correct a congenital or acquired deformity of the proximal femur. An orthopedic surgeon typically performs the operation in a hospital or ambulatory surgical setting. The operative report should make clear that the cut was at the femoral neck, rather than at the intertrochanteric or subtrochanteric femur, and describe the condition and intended correction.
Report 27161 when the documented work is an osteotomy at the femoral neck; the anatomic level and indication help distinguish it from other hip-region procedures. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral surgery reported with modifier 50, CMS pays at 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27161 billing questions
How is 27161 distinguished from an osteotomy at another part of the femur?
The operative report must identify the femoral neck as the site of the bone cut. An intertrochanteric or subtrochanteric osteotomy is a different service.
How does 27161 differ from the slipped femoral epiphysis codes?
Use the code that matches the documented treatment of the slipped epiphysis, such as closed or open treatment. Code 27161 describes an osteotomy at the femoral neck, while 27179 is the osteotomy code associated with slipped capital femoral epiphysis.
What documentation supports reporting 27161?
Document the femoral neck as the osteotomy site, the condition prompting surgery, and the corrective work performed. Include laterality and the operative details needed to show the extent of the procedure.
What postoperative care is included in the CMS global period?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days after surgery.
How are bilateral procedures and additional same-session procedures handled?
CMS pays bilateral surgery reported with modifier 50 at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others at 50%.
