@lilianna I'm sorry Mayo doesn't take your insurance. There are issues with the so called "advantage" plans. They limit the list of physicians they will cover to those within their own network which is a contract between them and the providers. They may also limit coverage to their list only within the state where you live. My physical therapist will not take advantage plans because they are always reviewing care after the fact if they had covered it, and they will reverse a decision and come back to the provider for reimbursement of money they had already paid out. That is too big a risk for a provider to accept particularly in a very small PT clinic. Places like Mayo with huge operating costs also need to make sure they will be able to pay their employees. before I chose my Medicare and insurance plans, I called the Mayo Billing office to make sure what I selected would be good at Mayo if I need care there in the future. I have been a surgical patient there, and would come back if I need care for a complex issue. When the next enrollment period comes around, you could select insurance that Mayo would also accept.
