CPT® Code 24110

The CPT® Code 24110 refers to the excision or curettage of a bone cyst or benign tumor located in the humerus, which is the long bone of the upper arm. A bone cyst is defined as a fluid-filled space within the bone, and it can manifest in various forms. One of the most common types is the unicameral or simple bone cyst, which is generally considered a benign lesion. Another type, though less common, is the aneurysmal bone cyst, characterized by vascular tissue that surrounds a blood-filled cystic lesion. In addition to cysts, there are several types of benign bone tumors that may require excision, including giant cell tumors, chondromyxoid fibromas, and enchondromas. The procedure associated with CPT® Code 24110 involves making an incision in the skin over the lesion site, which can be located in the humeral shaft or the distal end of the humerus. Following the incision, the soft tissues are carefully dissected to expose the lesion. If a cystic lesion is identified, the surgeon incises the bone to create a window, allowing access to the cyst. The fluid within the cyst is then aspirated and sent for laboratory 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 benign tumors are present, the procedure may involve excising the tumor along with a margin of surrounding healthy bone, ensuring complete removal of the lesion. This procedure is critical for addressing both bone cysts and benign tumors in the humerus, facilitating further treatment or recovery as necessary.
