i would agree with Marty. Prescribing is limited to those authorized by the state, generally licensed practitioners.
Signing the charts could be done as a midlevel, but that gives them the ability to write Rxs, which is NOT legal. Perhaps if they are not verified to write Rx's it would block them from that ability.
It would be a provider that should have to pay yearly fees to AC however.
It's probably simpler to write the note completely, then forward to the provider to sign.
