CPT® Code 40650

The procedure described by CPT® Code 40650 involves a full thickness repair of the vermilion, which is the pink to red portion of the lips. The lips are anatomically divided into three regions: the cutaneous, vermilion, and mucosal areas. The cutaneous region includes the outer skin of the lips, while the mucosal region is located inside the mouth, adjacent to the teeth. The vermilion is a critical area for cosmetic and functional purposes, as it plays a significant role in the appearance of the lips and their ability to function during speech and eating. In this procedure, the surgeon focuses solely on repairing the vermilion, ensuring that the submucosa is addressed first with nonirritating suture material, followed by the repair of the orbicularis oris muscle using absorbable sutures. The final step involves meticulously aligning the vermilion border to restore the natural appearance of the lips. This procedure is essential for patients who have experienced trauma or defects in the vermilion area, allowing for both aesthetic restoration and functional improvement.
