Teaching hospital?
You need to document the name/license of the assistant (MD, PA, NP, DO, etc), as well as that person's role as assistant.
Additionally, if you are in a teaching hospital, you much document the fact that no qualified resident/fellow was available to assist.
The assistant surgeon does NOT need to dictate a separate operative note. (Co-surgeons, however, must each dictate their own operative notes.)
Hope that helps.
