I have a provider that tends to see pts for their AWV, ACP and often a seperate E/M code on the same visit. Lately I am being told that insurance will not cover the ACP 99497 portion of the visit. We are billing it with a 33 modifier (which is how we have always billed it) I am at a complete loss. I've researched everything I can think of. Is there anyone with any experience in this area that can help me out?
