I think it will depend on the doctor, and how much they let the insurance company dictate their practice.
During my doctor shopping a couple years ago, trying to find someone who will work with me, I had one woman completely fuck up my medical history by putting down a bunch of baloney. I'm not (nor was I at the time) the leanest guy in the world, but I can see my toes when I stand up straight, ya know? Well this wonderful woman put "sever obesity" on my chart, and that shit has haunted me ever since.
This woman also lectured me on steroids because I could pull 405, and said that was too much stress for my body and wouldn't treat me if I continued to destroy myself with drugs and lifting unnatural weights.
Worst doctor appointment ever.
