What 24366 covers

The surgeon removes or reshapes the damaged radial head and places a prosthetic implant to restore the radial head’s role in elbow articulation and forearm rotation. This operation is performed by an orthopedic surgeon in an operating room, commonly when the radial head cannot be reconstructed adequately with the patient’s own bone. The operative report should identify the treated side and document the implant and the work performed on the radial head.

Report 24366 for radial head arthroplasty with an implant; distinguish it from implant-free arthroplasty and from open treatment of a radial head or neck fracture. For an acute fracture managed with prosthetic replacement, evaluate 24666, which describes the fracture treatment with replacement. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure setting, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 for a bilateral procedure is paid at 150%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

24366 billing questions

How does 24366 differ from 24365?

24366 describes radial head arthroplasty with a prosthetic implant. Use 24365 for the corresponding arthroplasty without an implant.

Should 24366 be reported for an acute fracture treated with a radial head prosthesis?

When the procedure is open treatment of a radial head or neck fracture with prosthetic replacement, evaluate 24666. That code describes the fracture treatment with replacement rather than separately reporting 24366 for the arthroplasty.

Can 24366 be billed with 24666 for the same radial head?

Do not separately report 24366 for the prosthetic replacement included in the fracture treatment described by 24666.

What documentation supports 24366?

Document the side, the radial head procedure, and the prosthetic implant placed. The operative report should also make clear whether the service was arthroplasty or open fracture treatment.

Can an assistant or co-surgeon be reported?

CMS may pay for an assistant at surgery. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.

How is a bilateral procedure handled?

For a bilateral procedure, report modifier 50; CMS pays the bilateral procedure at 150%.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
