CPT® Code 26432

The CPT® Code 26432 refers to the closed treatment of a distal extensor tendon insertion, which may occur with or without the use of percutaneous pinning, commonly associated with conditions such as mallet finger. Mallet finger is characterized by a flexion deformity of the distal interphalangeal joint, resulting in the inability to straighten the affected finger. This injury typically arises from a blunt force applied to the fingertip, leading to a tear or rupture of the distal extensor tendon. In certain instances, the injury may also involve an avulsion fracture, where a fragment of bone is pulled away along with the tendon. The closed treatment approach aims to facilitate healing of the damaged tendon while maintaining proper alignment and function of the finger. This is often achieved through the application of a splint that keeps the finger fully extended during the healing process. In cases where additional stabilization is necessary, a Kirschner wire may be utilized, which is inserted through the distal phalanx and across the distal interphalangeal joint into the middle phalanx, ensuring that the finger remains in an extended position to promote optimal recovery.
