CPT® Code 26492

Opponensplasty is a surgical procedure aimed at restoring thumb abduction, particularly in patients who have experienced median nerve damage. This condition often results in a loss of function in the thumb, which is critical for grasping and pinching movements. The procedure involves various techniques, including the transfer of tendons such as the palmaris longus, flexor digiti superficialis, extensor indicis, extensor digiti minimi, and flexor pollicis brevis, among others. Each technique is designed to re-establish the necessary muscle function to enable thumb movement. Specifically, CPT® Code 26492 refers to the method where a tendon graft is harvested from either the forearm or leg and then transplanted to the muscles and tendons of the palm and thumb. This grafting process is essential for restoring the abduction of the thumb, which is vital for hand functionality. The procedure may also involve the transfer of the flexor carpi ulnaris tendon, which is extended with the tendon graft to enhance the effectiveness of the surgical intervention. Overall, opponensplasty is a critical procedure for patients suffering from thumb abduction issues due to median nerve injuries, aiming to improve their quality of life and hand function.
