CPT® Code 26210

The CPT® Code 26210 refers to the excision or curettage of a bone cyst or benign tumor located in the proximal, middle, or distal phalanx of a finger. 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, though less common, is the aneurysmal bone cyst, 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. The procedure involves making an incision over the lesion site in the phalanx of a finger, 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 access to the cyst for fluid aspiration, which is then sent for laboratory analysis. The curettage process involves using a curette to remove the lining of the cystic cavity completely. In cases where benign tumors are present, the procedure may involve excising the tumor along with a margin of healthy bone to ensure complete removal. This procedure is critical for addressing bone cysts and benign tumors in the fingers, facilitating proper treatment and recovery.
