What 24665 covers
This operation treats a radial head or neck fracture through an incision, allowing the surgeon to expose and restore the bone and stabilize it with fixation; fragment excision may also be part of the treatment. Orthopedic surgeons typically perform it in an operating room when the fracture requires direct surgical management rather than closed treatment.
Choose 24665 when the native radial head is treated without prosthetic replacement; use 24666 when a radial head prosthesis is placed. The operative report should identify the fracture site, open approach, treatment performed, and whether fixation or excision was used. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one 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.
