if documentation supports both services you can split bill it as you have it, with a modifier on the 99213. But documentation has to be able to "stand alone" and support each visit separately. (when our providers do this we have them dictate separate notes to support each service) The consult is going to need to meet all 3 components and the 3 R's - (request, render, report), and the level 3 E/M will need to stand alone in it's services. It might be kind of difficult to pull out a level 3 consult AND level 3 E/M. You could probably pull out a 99242 & 99213.25 or visa/versa - 99243 & 99212.25. If documentation doesn't support both levels - independently of the other, well - then you only have one service.
{that's my opinion on the posted matter}
