Okay thanks guys. Well she told me last night that I would be using their system. Basically they would do the billing, send it to me, I would review it and add modifiers if needed and then send it to their clearinghouse. They would also need me to follow up on unpaid and rejected claims and then have patients call me with billing inquiries. I have no idea how I would charge for this. I do percentage billing with my other clients (which I hate) but I don't think that would work for this situation. Do you have any suggestions?
