CPT® Code 25350

An osteotomy of the radius, specifically at the distal third, is a surgical procedure aimed at correcting a deformity or realigning the bone structure of the radius. The term 'osteotomy' refers to the surgical cutting of bone, which is performed to address various deformities that may affect the functionality and alignment of the arm. The specific location of the osteotomy, in this case, the distal third of the radius, is chosen based on the nature and site of the deformity being treated. Different types of osteotomies can be employed, including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy, each tailored to achieve the desired correction. Prior to the surgical intervention, the physician utilizes radiographic studies to accurately determine the optimal site for the bone cut, ensuring that the procedure is planned effectively to achieve the best possible outcome. The surgery involves making an incision over the radius, followed by careful dissection of the soft tissues to expose the bone. The periosteum, a layer of connective tissue surrounding the bone, is elevated to facilitate access. The actual osteotomy is performed using surgical instruments such as a drill, saw, or osteotome to create the necessary bone cut. In some cases, bone grafts may be inserted between the cut segments to promote healing and stability. To maintain proper alignment of the bone after the cut, various internal fixation devices, such as pins, screws, or plates, may be utilized. Alternatively, an external fixation device can be applied if deemed appropriate. This procedure is coded as CPT® Code 25350, specifically for osteotomy of the distal radius, while CPT® Code 25355 is designated for osteotomy of the middle or proximal radius.
