CPT® Code 26478

The procedure described by CPT® Code 26478 involves the lengthening of a flexor tendon in the hand or finger. This surgical intervention is typically indicated for correcting a flexion deformity, which can occur due to various factors, including the late effects of injuries or chronic conditions such as severe rheumatoid arthritis or osteoarthritis. The flexor tendons are responsible for bending the fingers and hand, and when they become too short or tight, they can lead to a condition where the fingers cannot fully extend, resulting in a deformity. The surgical technique for lengthening the tendon involves making a skin incision over the affected tendon, followed by careful dissection of the surrounding soft tissues to expose the tendon. A Z-shaped incision is then created in the tendon itself, which allows the tendon fibers to slide apart when the wrist is flexed or extended, effectively lengthening the tendon. After the tendon is lengthened, sutures are placed to secure it in this new, elongated position. To ensure proper healing and maintain the length achieved during the procedure, the hand or finger is immobilized in 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.
