What 24370 covers

An orthopedic surgeon uses this service to revise both the humeral and ulnar components of a previously implanted total elbow replacement. The operation may address problems such as loosening, wear, or instability of the prosthesis. It is generally performed in a hospital operating room, with the surgeon removing or revising the existing components and reconstructing the joint as needed. Allograft used during the revision is included in the service.

Report this code when the operative documentation supports revision of both components; use the related one-component revision code when only the humeral or ulnar component is revised. Document the prior elbow replacement, the condition prompting revision, and which components were revised. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 bilateral procedures are paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
