Welcome, @backyarder1.
@karina77 is right. You can self-refer to Mayo Clinic. Here is the contact information: http://mayocl.in/1mtmR63
When you call, you can also talk to them about insurance coverage. Mayo Clinic generally doesn't require a doctor's referral. But your insurance might. It's a good idea to check with your insurance company. If you need a referral, we can help you through the process.

I think you'll also appreciate these Frequently Asked Questions about appointments at Mayo Clinic:
