CPT® Code 21034

The CPT® Code 21034 refers to the excision of a malignant tumor located in the maxilla or zygoma, which are critical structures in the facial skeleton. The maxilla is the upper jawbone, while the zygoma, also known as the cheekbone, contributes to the structure of the face. This procedure is performed by a physician who specializes in surgical oncology or maxillofacial surgery. The primary goal of this surgical intervention is to remove the malignant tumor along with a margin of healthy tissue to ensure that all cancerous cells are excised, thereby reducing the risk of recurrence. The physician may employ various surgical techniques to access the tumor, which may include dissection of the surrounding tissues to reach the tumor effectively. During the excision, the physician utilizes specialized instruments such as saws, osteotomes, files, and drills to carefully remove the tumor mass. Depending on the size and location of the tumor, the procedure may necessitate the removal of adjacent teeth. Following the excision, soft tissue reconstruction may be required, which could involve the use of myocutaneous flaps to restore the anatomical integrity of the area. The final step of the procedure involves closing all incisions with sutures to promote healing and minimize scarring.
