Dan,
About 7 years ago I heard a speaker (family doc), at a Pa. AFP seminar, reporting that virtually every visit of his was a 214. He got paid for all of them, and had no problems with the occasional audit that he was subject to.
In my experience, the only potential problem based on percentage of visit coding, was a Medicare letter received by an ENT. He was flagged for coding all office visits as 213s, the norm for that specialty was about 5% 212, 70% 213, 25% 214. They suggested that he review his coding procedures.
He never heard back from them afterward.
