Now I’m confused. I have ALWAYS been taught if the provider is billing for eg: and 99213 and 92552 (hearing test for hearing problem). I should add a mod 25 to the 99213. Basically anytime there is a procedure or "service" being done we should add a modifier 25 with the exception of 8xxxx codes (lab type codes). Now I’m being told that everything I had be told in the past is wrong. Can someone help me please!!!
Thank you
