What 24110 covers
An orthopedic surgeon removes or curettes a cystic or benign bone lesion in the humerus, the upper-arm bone. The procedure is performed in an operating-room setting and may involve opening the affected bone to remove lesion tissue. This code distinguishes the humeral site and the procedure without the grafting specified by related codes.
Choose the code from the operative report’s documented site and treatment: the lesion must be in the humerus, and the work must be excision or curettage of a bone cyst or benign tumor. Record the lesion and the procedure performed, including whether grafting was part of the service. This major surgery has 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 others at 50%. 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.

This code describes humeral cyst or benign tumor excision or curettage without the grafting specified by those codes. Use the operative documentation to identify whether grafting was performed and which type.

No. The site for this code is the humerus; 24120 is the related code for a bone cyst or benign tumor in the radius without grafting.
What documentation supports reporting this service?
The operative report should identify the humerus as the treated bone and describe excision or curettage of a cyst or benign tumor. It should also make clear whether bone grafting was performed.

CMS pays bilateral reporting with modifier 50 at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%.
