Talk to the provider about why they are unhappy with the current billing service. If you know what was going wrong you can talk to the provider about how you will handle things so that these same problems won't occur. You also must have confidence in yourself and be able to communicate that confidence. You have been doing billing for a long time and you know what you are doing. (I do know this to be true as I know aksharhealth) Try not to be nervous. Don't talk too much. Get the provider to reveal as much as possible. Good luck! Hope the ankle is doing well now.
