First, let me say that I'm so sorry you are in this situation. You are definitely NOT being "over sensitive". You sound like such a diligent and conscientious worker. I agree with the others, that if you can get out and go elsewhere, do so.
But, I picked up on a few other nuances. The "good" thing is, now you KNOW that he is actively trying to trick you, so (1) you can keep an extra eye on his charts and be sure to query him about EVERYTHING. (2) What does your supervisor say about all this? Does your supervisor support you? If so, and I tend to think so or s/he wouldn't have told you about this setup scheme, work together to create a plan to keep on top of this doctor. If your supervisor does not support you, then, yes, you need to get out, or grit your teeth and follow the advice of joykaye8.
Wishing you the best...
