CPT® Code 25270

The procedure described by CPT® Code 25270 involves the surgical repair of extensor tendons or muscles located in the forearm and wrist. Extensor tendons and muscles are crucial for the extension movements of the wrist, hand, and fingers, and they originate from specific anatomical landmarks, including the lateral epicondyle and lateral supracondylar ridge of the humerus, as well as the proximal dorsal surface of the ulna. Key muscles involved in this procedure include the extensor carpi radialis longus, extensor carpi ulnaris, extensor digitorum, and extensor indicis. Surgical intervention may be necessary due to various types of injuries, which can be classified as either open injuries, such as lacerations or punctures, or closed injuries, such as ruptures or avulsions. During the procedure, an incision is made directly over the affected tendon or muscle to access the site of injury. If the extensor tendon has been completely severed, the surgeon locates the ends of the tendon, which may be pulled either distally or proximally to facilitate repair. The tendon is then sutured back together. In cases where the tendon is only partially transected, the surgeon repairs the damaged fibers. If the muscle itself has sustained a laceration or tear, the repair involves suturing the muscle tissue in layers to restore its integrity. For accurate reporting of this procedure, CPT® Code 25270 is utilized to indicate the primary suture repair of a single extensor tendon or muscle. Should the primary repair fail to achieve the desired functional outcome, a secondary repair may be necessary, which is reported using CPT® Code 25272. In more complex cases requiring a free graft, CPT® Code 25274 is applicable, where a local tendon graft is harvested and attached to the remnants of the severed tendon. Post-surgery, the surgical site is closed in layers, and the wrist and hand are immobilized with a splint or cast to promote healing and restore function.
