CPT® Code 28102

Excision or curettage of bone cyst or benign tumor, talus or calcaneus; with iliac or other autograft (includes obtaining graft)

The CPT® Code 28102 refers to the surgical procedure involving the excision or curettage of a bone cyst or benign tumor located in the talus or calcaneus, which are bones in the foot. This procedure is performed with the use of an iliac or other autograft, which includes the process of obtaining the graft. A bone cyst is defined as a fluid-filled space within the bone, and it can be classified into various types. The unicameral or simple bone cyst is a common benign lesion, while the aneurysmal bone cyst is characterized by vascular tissue surrounding a blood-filled cystic lesion. Additionally, benign bone tumors can include giant cell tumors, chondromyxoid fibromas, and enchondromas. The procedure begins with an incision made over the lesion site, followed by dissection of the soft tissues to expose the lesion. If a cystic lesion is identified, a window is created in the bone to access the cyst, allowing for fluid aspiration and laboratory analysis. The lining of the cystic cavity is then removed through curettage, or the benign tumor may be excised along with a margin of healthy bone. Following the excision or curettage, healthy bone is harvested from a separate site, typically the iliac crest, and is then packed into the defect created in the talus or calcaneus. This procedure is essential for addressing bone cysts and benign tumors, ensuring proper healing and structural integrity of the affected bone.
