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.

23180 billing questions
How is this code distinguished from partial claviculectomy?
Use this code for limited excision of clavicular bone. Compare the operative description with 23120, which represents partial claviculectomy; the documented procedure and extent determine the appropriate code.
When is clavicle sequestrectomy a better fit?
Use 23170 when the surgeon removes a sequestrum from the clavicle. This code describes partial bone excision rather than sequestrectomy specifically.
Can modifier 50 be reported for both clavicles?
Yes. CMS identifies this as a bilateral procedure; bilateral reporting with modifier 50 is paid at 150%.
Is the day-before visit included in the global period?
Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant-at-surgery be billed?
CMS lists a statutory restriction, so assistant-at-surgery payment is not made for this code. Co-surgeon payment requires supporting documentation.
