CPT® Code 25125

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

The CPT® Code 25125 refers to the surgical procedure involving the excision or curettage of a bone cyst or benign tumor located in the radius or ulna, specifically excluding the head or neck of the radius and the olecranon process. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type. The most common type is the unicameral or simple bone cyst, recognized as a benign lesion. Another type, the aneurysmal bone cyst, is characterized by vascular tissue surrounding a blood-filled cystic lesion. Additionally, there are various benign bone tumors, including giant cell tumors, chondromyxoid fibromas, and enchondromas. During the procedure associated with CPT® Code 25125, an incision is made over the lesion site on the radial or ulnar shaft or the distal radius or ulna. The soft tissues are carefully dissected to expose the lesion. If a cystic lesion is identified, the bone is incised to create a window, allowing access to the cyst. The fluid within the cyst is aspirated for laboratory analysis. A curette is then utilized to remove the lining of the cystic cavity completely. In cases where a benign tumor is present, the lesion is excised along with a margin of healthy bone. Following the excision or curettage, the procedure involves obtaining a healthy bone graft, either from the local area or a separate site, such as the iliac crest. This autograft is then packed into the defect created in the radius or ulna, facilitating proper healing and structural integrity of the bone.
