I was a patient at the Mayo a year ago for Prostate Surgery. I am 71 years old, on Medicare, with an AARP Supplemental Plan F. This insurance combination is accepted at the Mayo. They do not accept patients with Medicare Advantage Plans. Advantage Plans have lower premiums for you, but your out of pocket expenses (deductibles) are greater. I received a letter from Mayo Clinic last year explaining that they would no longer except Advantage Plan insured patients.
