Access to Mayo was quite easy. There is an online form to request an appointment for any of their 3 locations. It was followed up by a call with an appointment coordinator. My insurance is with United Health Care (not the AARP policy) and Mayo is in network. I do have a referral from my primary care doc, too, which was not needed. Had a 2nd appointment with the rheumatologist here in Santa Fe Thursday (the only one...) and told her I was going for care there. Was not met with much enthusiasm. A story for another time. Will let you know what I learn at the appointment. Cheers!
