CPT® Code 26476

The procedure described by CPT® Code 26476 involves the lengthening of an extensor tendon in the hand or finger. This surgical intervention is typically indicated for patients who present with an extension deformity, which can occur as a result of various conditions, including the late effects of injuries or chronic diseases such as severe rheumatoid arthritis or osteoarthritis. The goal of the procedure is to correct the deformity by adjusting the length of the extensor tendon, thereby restoring normal function and alignment of the affected digit. During the procedure, a skin incision is made over the targeted tendon, allowing for careful dissection of the surrounding soft tissues to expose the tendon. A Z-shaped incision is then created in the tendon itself, which facilitates lengthening by enabling the tendon fibers to slide apart when the wrist is flexed or extended. After the tendon has been lengthened, sutures are placed to secure it in this new position. To ensure proper healing and maintain the desired length of the tendon, the hand or finger is subsequently immobilized using a splint or cast. It is important to note that this code is applicable for each tendon that is lengthened during the procedure, emphasizing the need for accurate reporting in medical coding practices.
