One additional twist I just heard the other day about eRx. If the pharmacy you're eRx'ing to isn't set up to receive electronic prescriptions, the Rx clearinghouse falls back to faxing the script. Apparently, this is something that you won't see on your end, but because the pharmacy doesn't do things electronically, you don't get credit for the eRx, as far as Medicare is concerned, even if you bill the G8553 code.
