1. When billing or code 00170, insurance is wanting an appropriate modifier. I am a dental office that does oral surgery and we use conscious sedation (D9241 and D9242). What modifier do we need to be using? Our dentist is not an oral surgeon, but a sedation dentist that does oral surgery procedures. He has an RN that works with him during sedation procedures. 2. Is code 41899 still the appropriate medical procedure code to be using for extractions in the year 2015? Thanks
