Here's an update. I cleared his future schedules and inactivated his account. I am still receiving eRx refills for him. For patients that have transferred care to me (are on my future schedule) I am refilling the prescriptions. For those who have no scheduled f/u, I am denying with a note to the pharmacy that the physician is no longer in practice and to send refill requests to patient's PCM. So far it's working ok.
I have not tried to inactivate him in NC, but I'm planning to try in a month or two.
