Osteotomy, clavicle, with or without internal fixation; with bone graft for nonunion or malunion (includes obtaining graft and/or necessary fixation)

An osteotomy of the clavicle, as described by CPT® Code 23485, is a surgical procedure aimed at correcting structural issues of the clavicle, particularly in cases of malunion or nonunion. Malunion refers to the improper healing of a fractured bone, while nonunion indicates that the bone has failed to heal altogether. This procedure may also be indicated for chronic dislocation of the sternoclavicular joint. The osteotomy involves making precise cuts in the clavicle to realign it properly. The specific location of the osteotomy is determined based on the underlying condition being treated. In this procedure, bone grafting is utilized to facilitate healing and ensure proper bone integration. The graft can be harvested from the patient’s own body, often from the iliac crest, or it may be obtained from another site. The surgical technique includes creating drill holes, making horizontal and vertical cuts to form a Z-osteotomy, and securing the bone with sutures or internal fixation devices. This comprehensive approach aims to restore the normal anatomy and function of the clavicle, ultimately improving patient outcomes.
