Teaching E/M to co-worker

[jccoder]

I was pretty much self-taught (reading everything I could) when I started coding E/M visits. I now need to teach a fellow co-worker how to code E/M, looking for any suggestions on how to go about doing this in a timely and accurate manner. Another co-worker looks at the 95 (what we use) guidelines--just as guidelines and relies on the MDM to assign her codes.
