My provider asked me to run a report of E/M’s billed (99213-99215) over the past two months; mostly out of curiosity. Our 99215 visits are very low and he’s thinking that some of his level 4’s could have been level 5’s based on the complexity of his patients. I’ve read over the requirements in the CPT book and skimmed over the lengthy E/M guidelines from CMS, however, I’m wondering if any of you can provide me with a link to a document/table that I can show him to make it easier to reference to. I’ve been looking and haven’t had great luck. I may make my own but was hoping someone might have a good starting point for me. (I’m a fairly new biller) Main interest is comparison between 99214 vs 99215.

Also, when does time come into play? I know 99215 states 40min; need some guidance on whether or not that needs to be documented in the note if he bills based on MDM vs time.

I appreciate your time very much!!!
