Danielle, I do the exact same thing. A couple of weeks ago I had a situation where one of our cardiothoracic surgeons dictated a note stating that he and the entire team were on-call for 4 hours while a child was undergoing cardiac catheterization just in cast a catastrophic event occurred. I had never seen that before and I was wondering how that would have been coded. Ironically while doing the Medicine section of Module II I ran across the code for being on-call.
