CPT® Code 24371

The CPT® Code 24371 refers to the procedure known as the revision of total elbow arthroplasty, which is a surgical intervention aimed at correcting issues related to previously implanted elbow joint components. This procedure is typically indicated in cases where there is component loosening, joint instability, infection, or periprosthetic fracture. During the revision surgery, the surgeon reopens the old incision over the elbow joint to access the internal structures. The ulnar nerve, which runs along the inner side of the elbow, is carefully identified and protected to prevent injury during the procedure. The surgical approach involves exposing the ulnar component of the prosthesis, 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 during the operation. The humeral component, which is the part of the prosthesis that replaces the upper arm bone, is similarly exposed, and any loose cement is removed. The surgeon evaluates both the ulnar and humeral components to determine if they need to be replaced or repositioned. In cases where infection or necrotic bone is present, debridement of the affected tissues is performed to ensure a healthy environment for the new or repositioned components. The components are then secured in place using allograft bone, cerclage wires, and/or bone cement, and are locked together with a pin to create a stable hinged prosthetic joint. After the components are secured, the surgeon reattaches ligaments and tendons, medializes the triceps muscle, and creates a subcutaneous pocket for the ulnar nerve to ensure it is properly positioned. Finally, the fascia and skin are closed in layers, and the arm is placed in a splint to facilitate recovery. This code is specifically used when both the humeral and ulnar components are revised, distinguishing it from CPT® Code 24370, which is used when only one of the components requires revision.
