CPT® Code 24125

Excision or curettage of bone cyst or benign tumor of head or neck of radius or olecranon process; with autograft (includes obtaining graft)

The procedure described by CPT® Code 24125 involves the excision or curettage of a bone cyst or benign tumor located in the head or neck of the radius or the olecranon process. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type. The unicameral or simple bone cyst is the most common, characterized as a benign lesion. In contrast, an aneurysmal bone cyst is less common and consists of vascular tissue surrounding a blood-filled cystic lesion. Additionally, there are various types of benign bone tumors, including giant cell tumors, chondromyxoid fibromas, and enchondromas. The procedure begins with an incision made over the lesion site, followed by dissection of the soft tissues to expose the lesion. If a cystic lesion is identified, the bone is incised to create a window, allowing for the aspiration of fluid, which is then sent for laboratory analysis. The lining of the cystic cavity is removed using a curette. In cases where benign tumors are present, the lesion is excised along with a margin of healthy bone. Following the excision or curettage, the procedure includes the use of an autograft, where healthy bone is obtained either locally or from a separate site, such as the iliac crest, and packed into the defect created in the bone. This comprehensive approach ensures the effective treatment of the lesion while promoting healing through the use of the patient's own bone tissue.
