CPT® Code 21184

Reconstruction of orbital walls, rims, forehead, nasoethmoid complex following intra- and extracranial excision of benign tumor of cranial bone (eg, fibrous dysplasia), with multiple autografts (includes obtaining grafts); total area of bone grafting greater than 80 sq cm

The procedure described by CPT® Code 21184 involves the surgical reconstruction of the orbital walls, rims, forehead, and nasoethmoid complex following the excision of benign tumors from the cranial bone, such as fibrous dysplasia. This complex surgical intervention is performed under general anesthesia and requires the use of multiple autografts, which are bone grafts harvested from the patient's own body. The total area of bone grafting in this procedure exceeds 80 square centimeters, indicating a significant reconstruction effort. The surgeon gains access to the surgical site through various incisions, which may include those made in the eyelid or scalp, allowing for both intra- and extracranial approaches to effectively remove the tumors. After the tumors are excised, the affected bones are carefully fractured and repositioned to restore their proper anatomical alignment. The harvested bone grafts are then strategically placed to augment and stabilize the areas where the tumors were removed. To ensure the structural integrity of the facial bones, fixation devices such as wires, plates, and screws are utilized. Finally, the incisions are meticulously closed in layers to promote optimal healing and aesthetic outcomes.
