Hi John: I opened your site and it does say that the patient will be responsible for anything that Medicare does not cover. The problem is that they really don’t explain their position fully. People with Medicare think that they are completely covered and then are hit with a big bill. Even when my husband called them, and he is fully aware of their policy, they didn’t know how to explain it to him. Anyway, hope your info also will be helpful to anyone interested in Mayo. Thanks.
