About 24400: Humeral corrective osteotomy
Reports surgical cutting and realignment of the humerus to correct a bone deformity, with internal fixation used when needed.
An orthopedic surgeon cuts the humerus and changes its alignment to correct a deformity, such as a healed fracture that has left the bone malaligned. Internal fixation may be used to hold the corrected bone position, but it is not required for this code. The service is generally performed in an operating room, including a hospital or ambulatory surgery center, rather than as an office procedure.
Report the code for the humeral osteotomy itself, whether or not fixation is used. The operative report should identify the bone and deformity, describe the osteotomy and correction, and document any fixation. The code 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% multiple-procedure reduction. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

24400 billing questions
When should this code be chosen over 24410?
Use 24400 for a humeral osteotomy that does not meet the specific multiple-osteotomy and intramedullary-rod description of 24410. The operative report should support the actual number and type of osteotomies and fixation method.
Does internal fixation have to be used?
No. The code covers the osteotomy whether or not internal fixation is used.
Is related postoperative care separately reported?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. The operative report and follow-up documentation should distinguish care related to the surgery from any separately reportable service.
How is bilateral surgery handled?
For a bilateral procedure reported with modifier 50, CMS pays 150%. Document the procedure on both humeri.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, while other procedures are subject to the standard 50% multiple-procedure reduction.
