CPT® Code 23480

An osteotomy of the clavicle, as described by CPT® Code 23480, is a surgical procedure aimed at correcting various conditions affecting the clavicle, which is the bone connecting the arm to the body. This procedure is particularly indicated for issues such as chronic dislocation of the sternoclavicular joint, as well as malunion or nonunion of the clavicle. The term 'osteotomy' refers to the surgical cutting of bone, and in this case, it is performed without the use of bone grafting. The specific location of the osteotomy is determined based on the underlying condition being treated. The procedure involves making a skin incision over the designated site on the clavicle, followed by the exposure of the bone. Drill holes are created at both the lateral and medial sides of the planned osteotomy site, allowing for precise cuts to be made. A horizontal cut is executed between these drill holes, and additional vertical cuts are made to form a Z-osteotomy, which facilitates the lengthening of the clavicle by sliding the cut edges apart. The stabilization of the bone is achieved through the use of sutures or internal fixation devices, ensuring proper alignment and support during the healing process.
