I agree, as I pointed out, Joseph that there needs to be a link. The other numbers serve no purpose at all.
Our state doesn't require DEA numbers except on controlled scripts.
Here is an idea:
Why don't we write the scripts:
Medication: Hi pharmacist. My NPI number is 9999999999. Oh, by the way, I would like to write for Augmentin, etc. Just a joke.
And, Joseph, if you ask Roy, Paul or Brian, they will tell you I am obsessed with workarounds so I recognize a good one when I see one.
