Hi John,
Over the years I have had % 99214 (vs 99213) increase gradually. Ironically, I think it took even a further jump since starting the MU garbage. As long as I list and "address" 3 problems, I think the 99214 is justified, especially for a 3 or 4 mo recheck.
Earlier rechecks, esp to address just 1 item ( BP med adjustment ), are typically 99213. Sore throat/sinus infection/sore knee are typically 99213, UNLESS they also need BP meds adjusted etc.
I'm not billing a lot of annuals, usually bill 99214 based on problems addressed.
Major/int joint injections typically 99213 plus procedure code, unless other problems addressed, then 99214 and injection.
Very few 99215s
Most initial visits 99203s.
