What 24360 covers

An orthopedic surgeon performs this operation for a damaged, painful elbow joint by reshaping the joint surfaces and placing a soft-tissue membrane, commonly fascia, between them. The interposed tissue helps reduce direct contact between the surfaces while retaining the patient’s native joint rather than substituting an elbow prosthesis. It is generally performed in an operating room for selected patients with elbow arthritis or other substantial joint damage.

Report the code when the operative service includes elbow arthroplasty with membrane interposition, not for isolated tendon or ligament repair, debridement, or prosthetic elbow replacement. The operative report should identify the joint work and the membrane used. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose

24361Elbow arthroplasty
Choose 24360 when a soft-tissue membrane is interposed at the elbow. Code 24361 describes arthroplasty using a distal humeral prosthetic replacement.
24362Elbow arthroplasty
Code 24362 describes elbow arthroplasty with an implant and fascia; 24360 is the membrane-interposition procedure.
24363Elbow arthroplasty
Code 24363 is for total elbow replacement. Use 24360 when the surgeon performs interposition arthroplasty instead of replacing the joint with a prosthesis.
24370Elbow revision
Code 24370 addresses revision of a prior elbow reconstruction. Code 24360 describes the interposition arthroplasty itself, not revision surgery.

24360 billing questions

How does this differ from a prosthetic elbow arthroplasty?

This code describes interposition of a soft-tissue membrane between joint surfaces. Prosthetic replacement procedures use different codes, such as 24363 for total elbow replacement.

Does this code include the membrane interposition?

Yes. The defining service is elbow arthroplasty with a soft-tissue membrane placed between the joint surfaces.

What documentation supports reporting this code?

The operative report should describe the elbow joint reconstruction and identify the membrane interposed. A note documenting only debridement or tendon or ligament work does not establish this service.

What is the Medicare global period?

It has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.

How is bilateral surgery handled?

For bilateral surgery, Medicare pays this procedure at 150% when reported with modifier 50.
