Orthopedic surgery
About 25491: Prophylactic ulna stabilization
Reports operative stabilization of an ulna weakened and at risk for fracture, such as from destructive bone disease, before a fracture occurs.
An orthopedic surgeon stabilizes the ulna before it breaks when disease or bone damage has made it vulnerable to fracture. The operation may use internal fixation such as a plate, pins, wires, or a nail; bone cement may also be used. A typical clinical setting is an operating room, with a destructive lesion, including one related to metastatic disease, creating concern for an impending fracture.
Choose this code when the operative goal is to prevent an ulna fracture, rather than to repair an existing fracture or a healing problem. The record should identify the ulna treated, the condition weakening the bone, the fracture risk, and the stabilization performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 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 services may be paid; co-surgeons and team surgery are not permitted.
