What 24566 covers

An orthopedic surgeon uses a percutaneous approach to manipulate and stabilize a fracture of the medial or lateral epicondyle at the elbow, typically with skeletal fixation such as pins or wires. The procedure is performed in a surgical setting, often with imaging to guide reduction and fixation. The fracture site is the epicondyle, not the supracondylar region or the humeral condyles.

Report this code when the operative record supports percutaneous skeletal fixation and identifies the epicondylar fracture, laterality, manipulation, and fixation performed. Choose a closed-treatment code when the fracture is managed without percutaneous skeletal fixation, or an open-treatment code when the fracture is exposed for fixation. Medicare 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%. Modifier 50 bilateral reporting is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

How to choose

24565Fracture treatment
Use 24565 for closed treatment with manipulation when percutaneous skeletal fixation is not performed. Use 24566 when percutaneous skeletal fixation is part of the treatment.
24575Epicondylar fracture repair
24575 describes open treatment of the epicondylar fracture. 24566 applies when fixation is performed percutaneously rather than through open exposure.
24538Humerus fracture fixation
24538 concerns a supracondylar humeral fracture, not a fracture of the medial or lateral epicondyle.
24582Humeral fracture fixation
24582 is for a humeral condylar fracture. Select 24566 when the documented fracture involves an epicondyle.

This code describes fixation through a percutaneous approach. Use the open-treatment code when the fracture is exposed for fixation.

What documentation supports 24566?

The operative report should identify the medial or lateral epicondyle fracture, laterality, manipulation, and percutaneous skeletal fixation performed.

Does the fracture care global period include follow-up?

Yes. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant surgeon be paid for 24566?

Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.

How is bilateral reporting handled?

When the procedure is performed bilaterally and reported with modifier 50, Medicare pays 150%.
