I am not sure where I learned it - have been using beta since day 1. I have also talked with Jon and other AC team members at conventions when version 5 was first coming out and looked at some demos. There is a demo video at
www.amazingcharts.com/5beta but I am not sure if it shows codifying meds.
There are lots of new features that taking getting used to - allergies are not autocodified and you will have to manually enter allergies and code them - they will pull over ones you have put in the past, but they are italicized and not truly coded for allergy checking. That will take you a few seconds on most patients and after you manually put in those from the past you will want to remove the old italicized ones (a pain, but useful in the future when comparing scrips to allergies).
