CPT® Code 27726

The procedure described by CPT® Code 27726 involves the surgical repair of a fibula that has either not healed properly, known as nonunion, or has healed in an incorrect position, referred to as malunion. These conditions can lead to significant complications, including persistent pain, instability in the ankle joint, and potential shortening of the fibula, which may result in malrotation and further derangement of the ankle. The surgical approach typically involves making a lateral incision over the previous fracture site to access the affected area. Once the incision is made, the surgeon carefully dissects through the surrounding tissues to reach the site of the nonunion or malunion. An oscillating saw or osteotome is then utilized to perform an osteotomy, which is the surgical cutting of the bone. This step is crucial as it allows the surgeon to correct the length, rotation, and alignment of the fibula based on preoperative measurements. After the osteotomy, preliminary internal fixation is applied to stabilize the bone in its corrected position, ensuring that alignment is maintained. This alignment is confirmed through visual inspection and radiographic imaging. Depending on the specific needs of the case, additional internal fixation devices such as screws and plates may be employed, often with the assistance of fluoroscopic guidance to enhance precision during the procedure.
