When you say you did "everything" do you also mean patient billing as well?
Their PM system is THEIR's.. lock, stock and barrel, I have my own HIPAA compliant login and that's that. problem solved.
What concerns me though, that you asked about, is the 52 hours a week it took you to work the one account.
Basically the problem is that the people in the doctors office are not doing their jobs, or at least not doing it well and you are paying for it.
BTW...about using the providers own PM software, I wonder if the learning curve is going to go through the roof? How has it worked out for you? I mean, I took at look at eClinicalWorks and couldn't make heads of tails
