I agree that some doctors will change wholly inaccurate notes, but it is difficult to do months/years later. Further, if the doctor’s office has a hint of a possible med. mal. case then they never will cooperate with your request for changes. I always advise clients to write everything down, make copies, and then bring in the documents to the doctor’s appointment. Given how busy most offices are these days, many doctors will just put note right into your chart and you could be protected from this very situation.
