CPT® Code 26215

Excision or curettage of bone cyst or benign tumor of proximal, middle, or distal phalanx of finger; with autograft (includes obtaining graft)

The CPT® Code 26215 refers to the surgical procedure involving the excision or curettage of a bone cyst or benign tumor located in the proximal, middle, or distal phalanx of a finger, accompanied by the use of an autograft. A bone cyst is defined as a fluid-filled cavity within the bone, which can vary in type. The unicameral or simple bone cyst is the most common form, characterized as a benign lesion. In contrast, an aneurysmal bone cyst is less common and is composed of vascular tissue surrounding a blood-filled cystic lesion. Additionally, 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 in the finger's phalanx, 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 for the aspiration of fluid for laboratory analysis. The lining of the cystic cavity is then removed through curettage. In cases where benign tumors are present, excision is performed, removing the tumor along with a margin of healthy bone. Following the excision or curettage, an autograft is obtained either from the local area or a separate site, such as the iliac crest, and is packed into the defect created in the phalanx, facilitating healing and structural integrity of the bone.
