About 24470: Humeral hemiepiphyseal growth arrest
A pediatric orthopedic surgeon selectively arrests one side of a humeral growth plate to guide correction of a progressive angular deformity.
This operation slows growth on one side of a humeral physis while growth on the opposite side continues, allowing gradual correction of an angular deformity in a child who is still growing. It is typically performed by an orthopedic surgeon in an operating room. The growth plate, side of the deformity, and remaining growth potential guide whether growth modulation is an appropriate approach; it differs from cutting or reshaping the bone directly.
Report the service for the operative hemiepiphyseal arrest, with documentation identifying the humeral site, laterality, deformity, and procedure performed. CMS assigns a 90-day global period, which includes 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 other procedures are subject to the standard multiple-procedure reduction. For bilateral surgery, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.

24470 billing questions
When is this code chosen instead of a humeral osteotomy?
Use this code when the surgeon arrests growth on one side of the humeral physis to gradually guide alignment. A humeral osteotomy corrects alignment by cutting the bone.
Does the 90-day global period include postoperative visits?
Yes. Related postoperative care for 90 days is included, along with the day-before preoperative visit.
How is bilateral surgery reported?
CMS lists this as a bilateral procedure; modifier 50 is paid at 150%.
Can an assistant surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons and team surgery are not permitted under the CMS rules provided.
What documentation supports selecting this code?
Document the humeral physis treated, laterality, angular deformity, and the operative growth-arrest procedure. The record should make clear that growth modulation, rather than direct bone realignment, was performed.
