CPT® Code 21030

The CPT® Code 21030 refers to the excision of a benign tumor or cyst located in the maxilla or zygoma, which are bones in the facial structure. This procedure is performed through a technique known as enucleation and curettage. Enucleation involves the careful removal of the tumor or cyst in its entirety, while curettage refers to the scraping of the tissue to ensure that all remnants of the tumor are eliminated from the surrounding bone. The procedure can be approached in two ways: externally or internally. In an external approach, the physician makes an incision on the outer surface of the face, allowing for direct access to the tumor. This method requires careful dissection of the surrounding tissue to reach the tumor. Conversely, the internal approach involves making an incision within the oral cavity, which provides access to the tumor without visible scarring on the face. Regardless of the approach taken, the goal is to remove the tumor intact, ensuring that it is completely excised from the maxilla or zygoma. After the tumor is removed, the incision site is sutured closed to promote healing and minimize complications.
