CPT® Code 24116

The CPT® Code 24116 refers to the excision or curettage of a bone cyst or benign tumor located in the humerus, specifically with the use of an allograft. 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, recognized as a benign lesion that typically does not pose significant health risks. Another type, the aneurysmal bone cyst, is characterized by vascular tissue surrounding a blood-filled cystic lesion, which can be more complex in nature. Additionally, there are various benign bone tumors, such as giant cell tumors, chondromyxoid fibromas, and enchondromas, which may also necessitate surgical intervention. The procedure begins with an incision made over the lesion site in the humeral shaft or distal humerus, allowing for the dissection of soft tissues to expose the lesion. If a cystic lesion is identified, the bone is incised to create a window, enabling access to the cyst. The fluid within the cyst is aspirated for laboratory analysis. Following this, a curette is utilized 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. After the lesion is addressed, the defect created in the bone may be filled with either an autograft, which is bone harvested from the patient, or in the case of CPT® Code 24116, with an allograft, which is donor bone sourced from a tissue bank. This procedure is essential for addressing bone lesions while promoting healing and structural integrity in the affected area of the humerus.
