What 24685 covers
This service covers open surgical treatment of a fracture near the elbow at the upper end of the ulna, including the olecranon or coronoid region. An orthopedic surgeon typically exposes the fracture and restores the bone’s position; internal fixation is included when performed. The procedure is commonly done in an operating room for a fracture requiring open treatment rather than closed fracture care.
Report 24685 when the operative record supports open treatment of a proximal ulna fracture. Documentation should identify the fracture location and describe the open treatment and any fixation. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures at 50%. 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.
