• Here is the situation: dr X saw patient Y for lower left quadrant scaling and root planing using mandibular block anesthesia. He then used an antibacterial gel in each sulcus. while the patient was in the office he reviewed the patient's progress on smoking cessation and went over the results of a biopsy done on a previous visit. how do i code that?
