My husband, who had a small leukoplakia patch, started with an oral surgeon (DDS) who specializes in oral pathology (doesn't just pull teeth and such). After an initial biopsy of a tiny area showed moderate dysplasia, he was referred to an ear-nose-throat surgeon, or ENT (an MD), for an excisional biopsy, which removed the whole thing. That report came back showing squamous cell carcimona in situ, and he has since been checked regularly by a oral cancer specialist at Hopkins.

The oral surgeon was out-of-network for our medical insurance, so we paid in full and submitted the claims. ENT and cancer doc were in-network.
