I have 4-5 patients who I see for weekly therapy who I bill 99214+ 90838 (90636 if the appointment is shorter than normal for some reason). I have another one who is usually 99213+90838 but recently has been 99214 due to some recent developments and re-orientation of our work on a more acute problem. It helps that a couple of them are on lithium or are not infrequently suicidal. I agree with
@splik ; if the documentation is good and you are hitting the criteria in a justifiable way, what exactly is an audit going to be able to say to you? I've not yet had a problem getting this paid.
You're probably not going to get away with saying it's an hour of supportive psychotherapy in the long run, though, so I'd definitely be documenting an established modality of some kind.
