What 27450 covers
This service is an osteotomy of the femoral shaft or supracondylar region performed without internal fixation. An orthopedic surgeon may use it to change the alignment of the thigh bone, such as when correcting a deformity. The procedure is typically performed in an operating room; the operative report should identify the femoral site and describe the bone cut and correction made.
Select this code when the documented osteotomy is in the specified femoral region and is performed without internal fixation. The operative note should support the site, technique, and absence of internal fixation, distinguishing this service from the related code for an osteotomy with fixation. CMS assigns 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 the others are subject to the standard multiple procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27450 billing questions
How does this differ from 27448?
The key distinction is fixation: 27450 describes the femoral osteotomy without internal fixation, while 27448 is the related code when internal fixation is used. Check the operative report for the fixation method.
What documentation supports reporting this code?
The operative report should identify the femoral shaft or supracondylar site, describe the osteotomy and correction, and establish that internal fixation was not used.
How is a bilateral procedure paid?
CMS lists this as a bilateral procedure; reporting modifier 50 results in payment at 150%.
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 or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
