CPT® Code 25609

Open treatment of distal radial intra-articular fracture or epiphyseal separation; with internal fixation of 3 or more fragments

The CPT® Code 25609 refers to the open treatment of a distal radial intra-articular fracture or epiphyseal separation, specifically involving the internal fixation of three or more fragments. In simpler terms, this procedure is performed on the distal radius, which is the lower part of the outer bone of the forearm located near the wrist. An intra-articular fracture means that the fracture line extends into the joint, potentially affecting the joint surface's congruity. This type of fracture can lead to complications in the radial-carpal complex, which is crucial for wrist function. During the procedure, the physician makes an incision along the front and lateral side of the distal forearm to access the wrist fracture. Careful retraction of muscles and tendons is necessary to protect the median nerve, which runs through this area. In some cases, the pronator quadratus muscle may need to be severed from its attachment to gain better access to the fracture site. Once the fracture or epiphyseal separation is properly aligned, a small metal plate is utilized to stabilize the fractured pieces, which are then secured to the bone fragments using screws. It is important to note that this code is specifically used when three or more fragments are involved in the fixation process, distinguishing it from similar procedures that may involve fewer fragments.
