CPT® Code 26200

The CPT® Code 26200 refers to the excision or curettage of a bone cyst or benign tumor located in the metacarpal bones, which are the long bones in the hand that connect the wrist to the fingers. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type and presentation. One of the most common forms is the unicameral or simple bone cyst, characterized as a benign lesion that typically does not cause significant symptoms. Another type, the aneurysmal bone cyst, is less common and is composed of vascular tissue surrounding a blood-filled cystic lesion, which may lead to more pronounced symptoms or complications. In addition to cysts, there are various benign bone tumors that may necessitate excision or curettage, including giant cell tumors, chondromyxoid fibromas, and enchondromas. The procedure described by CPT® Code 26200 involves making an incision over the lesion site on the metacarpal bone, followed by dissection of the soft tissues to expose the lesion. If a cystic lesion is identified, the procedure includes incising the bone to create a window, allowing for the aspiration of fluid, 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 physician will excise the tumor along with a margin of healthy bone to ensure complete removal. This procedure is essential for alleviating symptoms, preventing complications, and ensuring proper healing of the affected area.
