I posted this same question on the EM University website, and this was the answer I received from Dr. Peter Jensen. Lots of different opinions.
Just an FYI....
I think you can take some elements of history, such as items in the HPI which can also be used in the ROS, but some carriers consider this double-dipping and do not allow it. Check with your own carrier. As far as elements of history from the MDM, I do not think you can do this. I think what youare saying is, if in the assessment and plan, the doc describes a problem as stable, can I use this statement to help complete the HPI based on the "status of chronic or inactive problems." I don't think you can do this. My advice is to have doctors "surrender" and structure the note so that there all three key components can stand alone. Any other approach is simply too risky.
