CPT® Code 25400

The procedure described by CPT® Code 25400 pertains to the surgical repair of a nonunion or malunion of the radius or ulna, specifically when this repair is performed without the use of a bone graft. A nonunion occurs when the fracture fragments fail to unite after an adequate period of healing, while a malunion refers to a situation where the fragments heal in an incorrect position, leading to potential complications. These complications can include osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement, which may result in functional impairment. During the procedure, the original fracture sites of the radius and/or ulna are surgically exposed to assess the condition of the nonunion or malunion. The evaluation determines the necessary repair technique, which may involve the application of internal fixation methods. In cases where a bone graft is not utilized, a compression plate may be employed to stabilize the fracture site. The procedure may also involve refracturing the bone to realign it properly in cases of malunion. The fixation device's stability and the alignment of the fracture are confirmed through radiographic imaging, ensuring that the repair is effective and that the bone is positioned correctly for optimal healing.
