Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 23490 covers

An orthopedic surgeon uses fixation to reinforce a clavicle that is weakened and at risk of fracture, such as from a destructive bone lesion. The service is preventive: the clavicle has not fractured. It may be performed in a hospital or other surgical setting, often in the context of orthopedic oncology care. The operative report should support why the bone was considered at risk and describe the stabilization performed.

Report this code for prophylactic reinforcement of the clavicle, not for fixation of an existing clavicle fracture or an osteotomy performed to correct bone alignment. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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 50% reduction. For bilateral procedures, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
