CPT® Code 25355

An osteotomy of the radius, specifically coded as CPT® 25355, is a surgical procedure aimed at correcting a deformity or realigning the bone in the middle or proximal third of the radius. The term 'osteotomy' refers to the surgical cutting of bone, which is performed to address various deformities that may affect the radius, the bone located in the forearm. The specific type of osteotomy performed can vary based on the nature and location of the deformity, with options including transverse, wedge, sliding, right or left angle, V-osteotomy, and Z-osteotomy. 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 tailored to achieve the desired alignment and correction. The surgical approach involves making an incision over the radius, followed by careful dissection of the soft tissues to expose the bone. The periosteum, a dense layer of connective tissue surrounding the bone, is elevated to facilitate access. The actual osteotomy is executed using surgical instruments such as a drill, saw, or osteotome to create the bone cut in the predetermined configuration. In some cases, bone grafts may be interposed between the cut segments to promote healing and stability. To secure the bone in its new position, various internal fixation devices, such as pins, screws, or plates, may be employed. Alternatively, an external fixation device can be used if deemed appropriate. It is important to note that CPT® 25355 is specifically designated for osteotomies performed on the middle or proximal radius, while a different code, 25350, is used for osteotomies of the distal radius.
