CPT® Code 25415

The procedure described by CPT® Code 25415 pertains to the surgical repair of a nonunion or malunion of both the radius and ulna bones, specifically performed without the use of a bone graft. A nonunion occurs when the fracture fragments fail to heal together after an adequate period, while a malunion refers to a situation where the fragments heal but in an incorrect alignment, leading to potential complications. These complications can include osseous abnormalities, incongruity of articular surfaces, soft tissue contracture, and nerve impingement, which may result in pain and functional impairment. During the procedure, the surgeon exposes the original fracture sites of the radius and ulna 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 compression technique is utilized, a compression plate is affixed over the fracture site and secured with lag screws to promote stability. If malunion is present, the surgeon may need to refracture the bones to realign them properly before applying internal fixation to maintain anatomical alignment. The procedure emphasizes the importance of ensuring the stability and correct alignment of the fracture, which is verified through radiographic imaging following the placement of the fixation device.
