Yes I actually after multiple phone calls turned to my Social Worker Lisa in Transplant Social worker dept. She contacted the finance people and now I'm working with one of them. So I would say begin by getting an Apt with the Social Workers in your particular area and see if they could help. I don't have a direct contact phone number to the person helping me but his name is David and I receive calls from him typically but did get a message to him once via the main Mayo number. I suggest using the Social Workers as a beginning as all the phone calls I made directly to finance sound like the ones you also have gotten. I'll be honest I feel that the Finiance dept is in my humble opinion not easy to work with. I have found 2 people I have talked with on the phone who were very helpful but rare. I'm sad to say. I truly love Mayo and all the great healthcare Workers I've met but I think the finance department could improve a bit.
Hope that helps
