CPT® Code 24370

The CPT® Code 24370 refers to the procedure known as the revision of total elbow arthroplasty, which may include the use of allograft tissue when performed. This surgical intervention is typically indicated for patients experiencing complications such as component loosening, joint instability, infection, or periprosthetic fractures that necessitate the replacement or adjustment of the elbow joint components. During the procedure, the surgeon reopens the previous incision over the elbow joint to access the underlying structures. The ulnar nerve is carefully identified and protected to prevent injury during the operation. The procedure involves the exposure of the ulnar component, followed by the removal of any loose bone cement that may be compromising the stability of the implant. The radial nerve is also identified and safeguarded as the humeral component is exposed and evaluated. If necessary, the surgeon may debride any infected or necrotic bone and tissue. Depending on the condition of the existing components, they may be replaced with new implants or repositioned to restore proper function. The final steps involve securing the components in place using allograft bone, cerclage wires, and/or bone cement, followed by the reattachment of ligaments and tendons, and the closure of the incision in layers. This procedure is crucial for restoring the functionality of the elbow joint and alleviating pain associated with the aforementioned complications.
