CPT® Code 25426

The procedure described by CPT® Code 25426 involves the surgical repair of a bone defect located in both the radius and ulna, utilizing an autograft. An autograft is a type of graft that is harvested from the patient's own body, ensuring compatibility and reducing the risk of rejection. This specific procedure is indicated for defects that are not the result of a nonunion or malunion of a fracture, meaning that the defect is not due to a failure of the bone to heal properly after a fracture. The surgical process begins with the preparation of the defect site, which is essential for successful grafting. An autograft is typically harvested from the iliac crest, a common donor site due to its accessibility and the quality of bone available. The procedure involves making a skin incision over the iliac crest, followed by stripping the muscle to expose the underlying bone surface. The surgeon then collects either cortical bone, which is dense and forms the outer layer of bone, or cancellous bone, which is spongy and found inside bones. The harvested bone is then shaped to fit the defect precisely, or in some cases, cancellous bone may be morcellized and packed into the defect to promote healing. To ensure stability and proper integration of the graft, internal fixation methods, such as pins or wires, may be employed. Additionally, a compression plate and screws or other forms of internal fixation are utilized to stabilize the bone during the healing process. It is important to note that CPT® Code 25426 is specifically designated for the repair of defects in both the radius and ulna, distinguishing it from CPT® Code 25425, which is used for repairs involving only one of these bones.
