What 24120 covers

An orthopedic surgeon removes or curettes a bone cyst or benign tumor in the radius or ulna. The procedure is generally performed in an operating room, with the operative approach and extent guided by the lesion’s location and the bone involved. The removed tissue may be submitted for examination, but the defining service is treatment of the bone lesion rather than joint biopsy or removal of the radial head.

Choose this code when the operative report identifies a cyst or benign tumor in the radius or ulna and describes excision or curettage without grafting. Use the graft-specific sibling when autograft or allograft is placed. 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 others at 50%; bilateral reporting with modifier 50 is paid at 150%. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

24120 billing questions

When should this code be chosen instead of 24125 or 24126?

Use 24120 for radius or ulna cyst or benign-tumor curettage or excision without grafting. The sibling codes distinguish procedures that include autograft or allograft.

How does this differ from code 24110?

The lesion procedure is similar, but 24110 is for the humerus. Code 24120 applies to the radius or ulna.

What documentation supports reporting this code?

The operative report should identify the radius or ulna, characterize the treated lesion as a cyst or benign tumor, describe excision or curettage, and clarify whether grafting was performed.

How is the 90-day global period handled?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

Can this procedure be reported bilaterally?

When the procedure is performed bilaterally, modifier 50 is associated with payment at 150%.

When is an assistant at surgery payable?

CMS payment for an assistant at surgery requires documentation of medical necessity. Co-surgeons and team surgery are not permitted.
