You don't have to keep track of who is using which guidelines, you just audit based on what is most advantageous to each note.
Your ortho specialist might want to use 1997 specialty exam, but your family practice might prefer 1995 guidelines. That's perfectly okay.
We're a very large practice, and while we generally follow 1995, and our provider compliance training focuses on 1995 guidelines. But if 1997 works better for a note we allow 1997. Our compliance plan specifically states that we will use whichever is best for the service provided.
