What 24164 covers

The orthopedic surgeon removes the artificial radial head component at the elbow, commonly during surgery for a failed, loose, painful, or infected implant. The procedure is performed in an operating room and may be part of a larger elbow operation. The operative report should identify the prosthetic radial head as the component removed and describe the work performed; removal of a native radial head is a different service.

Report this code when the documented procedure removes the radial head prosthesis, distinguishing it from removal of other elbow replacement components or excision of native bone. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are subject to a statutory payment restriction; co-surgeons require supporting documentation, and team surgery is not permitted.

How to choose

24130Radial head excision
Choose 24164 when the surgeon removes an implanted radial head. Choose 24130 when the procedure excises the patient’s native radial head.
24160Elbow prosthesis removal
24160 concerns removal of prosthetic humeral and ulnar elbow components; 24164 concerns removal of the prosthetic radial head.
24666Radial head surgery
24666 applies to operative treatment of a radial head or neck fracture with prosthetic replacement. It is not the code for removing an existing radial head prosthesis.

24164 billing questions

How does this differ from 24130?

24164 is for removing a prosthetic radial head. Code 24130 describes excision of the native radial head, not removal of an implant.

When would 24160 be more appropriate?

Use 24160 when the removed prosthetic components are the humeral and ulnar components of an elbow replacement. This code is for removal of the prosthetic radial head.

What documentation supports reporting 24164?

The operative report should identify the radial head prosthesis and document its removal. It should distinguish the implant from native radial-head bone and from other prosthetic components.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period. The code is classified as major surgery.

How are bilateral procedures and additional procedures paid?

Bilateral reporting with modifier 50 is paid at 150%. For multiple procedures in one session, the highest-valued procedure is paid in full and the others are subject to a 50% reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is restricted by statute. Co-surgeons are paid only with supporting documentation, and team surgery is not permitted.
