Well I'm curious to hear other's input on this but here's mine:
I have a hard enough time getting what I need from a provider to do their billing. Asking them to do a report card on our service would be much for most of the provider's I deal with. We do stay in contact with them regularly, try to meet to go over things, and verbally make sure they are content, see if they have any areas of concern or issues. But I've never asked them to fill out a score card. I've requested referrals, or testimonials. That's it.
