You have two ways to do NDC codes in Kareo. One is the line note, the other is to put it into the master file for the medication. We use the code ADD in the Ref Code box (to the right of the Line note box) for medications. If you click the drop down arrow on Ref Code, you'll see other choices for that box. Right now, we are not using any of the other choices.
We're also dumping Kareo in about a month, after 15 or 20 years (our ID number is in the low 4 digits - tech support always thinks I'm giving them the wrong number when I tell them what it is).
