Please be aware that Mayo now prioritizes privately insured patients over those that are Government insured—e.g. Medicare and Medicaid. In the specialties that are heavily in demand (e.g. gastroenterology) this means that if you are on one of the government programs and are anew patient, it is highly unlikely that you will get an appointment unless your condition is something very complex and unusual. This is no secret. The CEO announced it a couple of years ago.
