@rwinney the way it was explained to me last year was that Mayo does accept Medicare, but the different departments have differing amounts of people they accept for Medicare. Mayo is very popular and cannot accept everyone for every department. Thus even non Medicare patients may be turned away. I believe the best way would be to have your doctor refer you to Mayo and see what happens. There is also a phone number to call about being admitted. Some one on here probably knows more about this.
