Thank you for your information on insurance coding, as it is a very complex world. I am a dental associate in a practice that I do not feel is completely up to date on the rules and regulations behind the periodic, comprehensive, or periodontal exams that occur in conjunction with the hygiene visit. My office bills these exams under the practice ownerÕs name regardless of whether he actually completed the exam or is even in the office. I do not think this is acceptable under our state regulations but I cannot find any evidence against it. Can you help?
