I was very upset with the billing practices of Allen Endodontic with regard to the coding used for my initial visit to diagnose the need for a root canal. I was in considerable pain and away from my permanent residence. The coding used (D9310) indicated that it was a consultation rather than a 1-time emergency and/or distress visit. The result of which was that when I visited my regular dentist back home for my bi-annual periodic exam, that claim was denied due to the coding on the root-canal emergency diagnosis appearing as one of the two periodic exams I was eligible for in a year. When I called Allen Endodontic, I was told that they did not think they could change it, but would call me back. They never called back and I was out the $42 my regular dentist charged. There is available coding for seeing a specialist for an imminent dental problem that does not interfere with the two periodic exams I can have, but they were not willing to take the time to do that. Probably did not want to change coding for it because it was worth $165 to them, rather that a less expensive code. Very disappointed with their lack of follow-up and response to my inquiry.
