Thanks for all your input.
I'd have to review our contract to see if the down coding without chart review is permitted. As far as if it is legal regardless, I have no idea.
That said, the remedy to test appears to be more specific coding and using all the appropriate codes. If the down coding becomes more aggressive, I don't think we'll hassle with appealing with clinical documentation or take anyone to court. We'll just drop the contract. A lot of the non hospital systems around here don't take Aetna anymore. The large entities probably can negotiate more favorable terms. I cannot.
I'm just an independent primary care doc, a vestige from a long gone era. It's just a constant squeeze to exhaust all the cash and resources from primary care physicians until no one comes in to fill the ranks.
