Yes, I am on Medicare Advantage through United Health. I am on an HMO. The Mayo will not accept it. I have to change to a PPO in October (taking effect in January). That is considered national coverage. I spoke to the Mayo business office for an hour and they did not mention a fund that assists with finances. I am glad that yours worked out to be easy on your wallet, all things considered and feel free to get political with me. Whats happening is a travesty on every level.
