I believe what your are saying is that this physician is NOT coding acurately-- he is upcoding. Have you told them that you believe he is upcoding and shown them? When you told them this, they responded by telling you to ignore it? Then this is a serious fraud problem, since they have been informed that they are billing incorrectly and are chosing to continue. It is no longer an error-- they are chosing to bill fraudulently.
I agree with these previous folks. Get what they said in writing and document what you told them. If you have been told that your job is diagnosis only, not CPT, ask for that in your job description.
Ironically, your physician is probably doing the work for the higher code; he probably just isn't documenting enough of what he is doing. I'm sure he asks the patient how they are and doing the same exam he's done for 20 years on autopilot, and he's just not writing it all down if it is normal.
Unfortunately most coders need their jobs and fear losing them, for good reason. It is easier getting rid of you than arguing with the physician. If you have a compliance officer, this is their job and you should talk to them about how the documentation needs to improve. If you don't have one, or if you are it, can you set up a teaching meeting with the physician? You can say it is about 2009 updates and changes. Talk about the changes in 2009 ICD-9s and how some of them are more specific and require more documentation (for instance, the new fever codes) and then transition into what you see that is missing in the E/M documentation.
