CPT code 41821 denotes surgical excision of an operculum, a small tissue flap on the back or top of a tooth. This minor oral surgical procedure matters nationally because it addresses recurrent pericoronal problems—such as food impaction, hygiene challenges, and localized inflammation—that can lead to patient discomfort or more serious infection if untreated. The code is used by dental and oral surgery providers in outpatient dental offices and oral surgery clinics.
