What 24140 covers

The surgeon removes or reshapes a limited area of humeral bone, such as by creating or enlarging a cavity or removing a localized sequestrum. This may be performed for a focal bone problem, including devitalized bone associated with chronic infection. An orthopedic surgeon typically performs the operation in a hospital or ambulatory surgery setting, with the approach and extent guided by the affected humeral site and operative findings.

Select this code when the documented work is partial excision of the humerus, rather than a separately described procedure for a specific cyst or benign tumor, or a more extensive tumor resection. The operative report should identify the humeral site, the reason for excision, and the bone removed or reshaped. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral reporting with modifier 50, payment is 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

How to choose

24134Bone sequestrectomy
24134 is specifically for sequestrectomy of the shaft or distal humerus. Choose 24140 for partial humeral excision when that narrower site-specific service does not describe the operation.
24110Bone lesion excision
24110 identifies excision or curettage of a humeral bone cyst or benign tumor. 24140 describes partial bone excision without that lesion-specific service.
24150Bone tumor resection
24150 describes radical resection of a tumor in the humeral shaft or distal humerus. 24140 is for a more limited partial excision.
24145Bone excision
24145 covers partial excision of the radius or ulna; 24140 applies when the bone partially excised is the humerus.

24140 billing questions

How is this different from 24134?

24134 is for sequestrectomy at the shaft or distal humerus. Use 24140 when the documented service is a partial excision of the humerus and the more specific site-and-service description for 24134 does not fit.

When is 24110 a better fit?

Use 24110 for excision or curettage of a humeral bone cyst or benign tumor. This code describes partial humeral bone excision rather than that lesion-specific service.

What documentation supports reporting 24140?

The operative report should state the humeral site, the clinical reason for surgery, and the portion of bone removed or reshaped. Document whether the work involved localized removal of nonviable bone or another partial excision.

What postoperative care is included?

Medicare assigns a 90-day global period. It includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.

How does Medicare pay when other procedures are performed in the same session?

The highest-valued procedure is paid in full, and other procedures are paid at 50%. For bilateral reporting with modifier 50, this code is paid at 150%.

Can an assistant or co-surgeon be reported?

An assistant at surgery may be paid. Co-surgeons and team surgery are not permitted for this code.
