I would use their pre set up charts for most of my pt's. Only thing was I used a macro every time in the history as that check box system is useless. I would populate it with my own and the required number of elements for billing. Such as:
Onset
[__] sudden
[__] gradual
and then I just type an x into the box. I also had a huge macro for the second half of the chart. I basically recreated an IBEX type chart complete with all the boxes into epic. Studies obtained, consults, etc. I so miss ibex!!!!!
