If I am not going to do a separate office note so I only have a procedure to document I use addendum - have templates and I just choose - Addendum - changed to procedure in box on top - label the subject with for instance - corticosteroid injection of left knee and then use that template. When I bring up the pt. chart and look I can scan through and quickly see when it was last done (great for things you tell a patient they cannot do more than 2 times per year, etc).
This is great and you can make a superbill for the addendum at the end.
