What 24150 covers
An orthopedic oncologist typically performs this operation to remove a tumor involving the shaft or distal portion of the humerus, the upper-arm bone. The surgeon removes the tumor-bearing area as a radical resection rather than scraping or taking only a limited portion of bone. These procedures are generally performed in a facility operating room, with the resected specimen sent for pathologic examination. The operative report should identify the humeral site, tumor extent, and the resection performed.
Select this code when the operative service is a radical tumor resection at the distal or shaft humerus; a limited bone excision or curettage belongs to a different procedure category. CMS assigns a 90-day global period, including 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%. If performed bilaterally with modifier 50, CMS pays 150%. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
