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

What 23180 covers

An orthopedic surgeon removes a limited portion of the clavicle, using an approach suited to the location and extent of the abnormal bone. This may be performed for focal bone disease, including infected or nonviable bone, when the procedure is a partial bone excision rather than removal of a sequestrum alone or resection of a larger clavicular segment. The service is generally performed in an operating room, and the operative report should identify the clavicle and the portion excised.

Select this code from the work documented, not simply from the diagnosis: record the site, extent of bone removed, indication, and relevant operative findings. Distinguish a limited excision from partial or total claviculectomy and from sequestrectomy. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in one session, the highest-valued is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons require supporting documentation, and team surgery is not permitted.
