My confusion is do you enter a CPT code when you finish a visit - I put mine on a superbill as I leave room. If you know the CPT code you are going to use it really is no big deal to enter it - you don't have to click the boxes for each shot, EKG, PFT, etc - since you are not using it for PM. Just put the office code and hit save.
Now if you do not use ICD-9 codes and have never got into looking them up it could be a bit more work but you just have to get into the habit - it will also fulfill the criteria for a problem list as you need ICD 9 codes for the summary sheet to have diagnoses, etc.
My staff teases me and calls me "Rainman" because I am so good at coding. At least on our system right now, our 6.09 is running slowly. It isn't inviting to add more time in the room waiting for AC to pull up and change screens.
