CPT code 24365: Radial head reconstruction, without prosthetic implant2026 Medicare rate & RVUs

Medicare pays $605.56 for 24365 nationally in a facility.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 24365 covers

An orthopedic surgeon reconstructs the radial head, the upper end of the radius at the elbow, using native bone and, when needed, graft material. The operation may address a damaged or deficient radial head when reconstruction is chosen instead of prosthetic replacement. It is generally performed in an operating room, often in a hospital setting, and differs from treatment that fixes an acute fracture without reconstructing the radial head.

Report this code for reconstruction without a prosthetic implant; use the implant-specific sibling when an implant is used. The operative report should identify the reconstruction performed and whether graft material was used. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
