Rene,
So exactly how amicable is this? You could of course just give your former associate a copy of your enc file. I understand this would be a VERY generous and trusting way to handle the situation...but it would also be by far the least labor intensive.
How do you propose to identify these patients? Will you provide the records for all of the patients seen by the associate? Will you wait until each one has been requested?
Do you have Updox?
