CPT® Code 25645

The CPT® Code 25645 refers to the open treatment of a fracture involving one of the carpal bones, excluding the carpal scaphoid (navicular) bone. Carpal bones are the eight small bones that make up the wrist, arranged in two rows. The proximal row consists of the scaphoid, lunate, triquetrum, and pisiform, while the distal row includes the trapezium, trapezoid, capitate, and hamate. When a fracture occurs in any of these bones, it can be treated through various methods, including closed treatment without manipulation, closed treatment with manipulation, or open treatment. The open treatment approach, as indicated by this code, involves a surgical procedure where an incision is made to access the fracture site directly. This allows for the identification and cleaning of the fracture area, followed by the reduction of the fracture fragments to restore proper alignment. In some cases, internal fixation devices such as screws or wiring may be utilized to stabilize the fracture. It is important to note that if multiple carpal bones are fractured, each bone's treatment must be reported separately. Additionally, radiographs are typically obtained to confirm the presence and alignment of the fracture, and a neurovascular examination is performed to ensure the integrity of the nerves and blood vessels surrounding the injury.
