@dandl48 Mayo Clinic does accept Medicare Advantage Plans. The Medicare Advantage that is accepted depends on several factors including state regulations which are different for Florida vs. Arizona vs. Minnesota. It may also depend on the specific practice area, again, varying by state. I write this because I do know several people who have Medicare Advantage Plans and have received treatment at Mayo Clinic in Minnesota.

The only way for a person to know if their insurance plan would be accepted at the Mayo Clinic campus that they are interested in is to do the following:

Contact the Mayo Clinic Billing Department:

Contact their Medicare Advantage Insurance company such as United Health Care or Blue Cross/Blue Shield - whatever insurance company they signed up with to manage their Medicare.

I hope this this explanation is helpful to you and to others who are similarly confused about what insurance Mayo Clinic does and does not accept.
