CPT® Code 23140

The CPT® Code 23140 refers to the excision or curettage of a bone cyst or benign tumor located in the clavicle or scapula. A bone cyst is defined as a fluid-filled space within the bone, which can vary in type and characteristics. 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 less common and is characterized by vascular tissue that surrounds a blood-filled cystic lesion. In addition to cysts, there are various benign bone tumors, including giant cell tumors, chondromyxoid fibromas, and enchondromas, which may also necessitate surgical intervention. The procedure begins with an incision made over the lesion site on the clavicle or scapula, 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. A curette is used to remove the lining of the cystic cavity completely. In cases where benign tumors are present, the procedure involves excising the tumor along with a margin of healthy bone to ensure complete removal. This code is essential for accurately documenting and billing for the surgical management of these conditions in the specified anatomical locations.
