What 25420 covers
An orthopedic surgeon uses this service to correct a nonunion or malunion involving both the radius and ulna. The operation addresses the abnormal healing of both forearm bones and uses the patient’s own bone graft to support repair. It is typically performed in an operating room; the code’s grafting work includes obtaining the autograft.
Report this code when the operative documentation supports repair of both bones and use of autologous graft, rather than repair of only one bone or repair without graft. The record should identify the nonunion or malunion, the bones treated, and the graft used. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral reporting with modifier 50, CMS pays at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
