I'm no kinda police either but I would be afraid of any Rx being generated by other than the Licensed Physician. Have the Doctor review the laws in your state for that. In California you can't delegate this, (and no I never ever had a staff member refill "any refills for BP meds until I get back from vacation" or any thing of the sort, we all use to do something like that, but with an EMR it is a thing of the past).
Maybe the safe thing to do is have the unlicensed forward the chart to the supervising physician. The problem then becomes closing the chart and keeping any of these "coaching fees" out of the insurance billing, as this is not likely a legitimate covered service.
interesting problem.
