Orthopedic surgery
About 27466: Femoral lengthening osteoplasty
Reports surgical lengthening of the femur to address a documented limb-length discrepancy or shortening through a planned bone-lengthening procedure.
An orthopedic surgeon lengthens the femur by surgically dividing the bone and gradually increasing the distance between the bone ends, with stabilization during healing. The procedure is generally performed in an operating room for a patient with a clinically significant femoral length discrepancy, including congenital or acquired shortening. The operative report should identify the femur treated and describe the lengthening procedure and stabilization used.
Report this code when the operation lengthens the femur; distinguish it from procedures directed at shortening the bone, correcting alignment, or using a specifically described intramedullary lengthening device. Documentation should support the indication, side, operative method, and work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

27466 billing questions
How is this code distinguished from 27458?
Use this code for femoral lengthening when the procedure documentation supports this service. Code 27458 is the nearby code associated with femoral osteotomy and an intramedullary lengthening device; follow the operative method documented.
Can this code be reported with a separate femoral osteotomy code?
The lengthening procedure itself includes the femoral bone work involved in achieving length. Do not separately report another code for work that is part of that same procedure.
What supports reporting the code?
The operative report should document the femur and side, the reason for lengthening, the bone-lengthening method, and stabilization. The record should make clear that the operation lengthened the femur rather than simply correcting its alignment.
How is bilateral femoral lengthening reported?
CMS recognizes bilateral reporting with modifier 50, paid at 150%. The record should support that the procedure was performed on both femurs.
Does the 90-day global period include postoperative visits?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.
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.
