CPT® Code 25130

The procedure described by CPT® Code 25130 involves the excision or curettage of a bone cyst or benign tumor located within the carpal bones, which are the eight small bones that form the wrist joint. A bone cyst is characterized as a fluid-filled space within the bone, and it can manifest in various forms. One common type is the unicameral or simple bone cyst, which is a benign lesion that typically does not pose a significant health risk. Another type, the aneurysmal bone cyst, is less common and is composed of vascular tissue that surrounds a blood-filled cystic lesion. Additionally, there are several types of benign bone tumors that may be encountered, including giant cell tumors, chondromyxoid fibromas, and enchondromas. During the procedure associated with CPT® Code 25130, the physician initiates the process by making an incision in the skin directly over the lesion located in the carpal bone. Following this, the soft tissues are carefully dissected to expose the lesion. If a cystic lesion is identified, the physician incises the bone to create a window, allowing access to the cyst. The fluid within the cyst is then aspirated and sent to a laboratory for analysis, which is reportable separately. A curette is subsequently inserted through the bone window to completely remove the lining of the cystic cavity via curettage. In cases where a benign tumor is present, the procedure may involve excision instead of curettage. The lesion is exposed in a similar manner, and the physician excises the benign lesion along with a margin of surrounding healthy bone to ensure complete removal. This procedure is critical for addressing bone cysts and benign tumors in the wrist, facilitating recovery and preventing further complications.
