CPT® Code 24331

Flexor-plasty of the elbow, specifically described by CPT® Code 24331, is a surgical procedure aimed at repairing the flexor-pronator complex at the elbow joint. This procedure is indicated for cases where there is a complete or partial detachment of the flexor-pronator complex, or when there is a need to enhance the flexion capability of the elbow. The surgery involves making an incision over the elbow joint to access the underlying structures. During the procedure, the ulnar nerve is carefully dissected and protected to prevent any nerve damage. If the flexor-pronator complex remains intact, it is surgically detached along with a segment of the medial epicondyle using a chisel. The flexor group is then meticulously dissected, and a planned attachment site on the humerus is drilled to facilitate the reattachment of the flexor group. This group is then transferred proximally by 2-6 cm and secured to the medial or mediovolar surface of the humerus using a fixing wire or screw fixation, which may also be applied to stabilize the epicondyle fragment. In addition to these steps, CPT® Code 24331 includes the advancement of the lateral extensor group, which is released, transposed proximally by 3-7 cm, and fixed to the humerus in a similar manner, thereby enhancing the overall function and stability of the elbow joint.
