Request an appointment By Mayo Clinic Staff Print Mayo Clinic works with hundreds of insurance companies and is an in-network provider for millions of people. In most cases, Mayo Clinic doesn't require a physician referral. Some insurers require referrals, or may have additional requirements for certain medical care. All appointments are prioritized on the basis of medical need. Appointments can often be arranged quickly — sometimes within two business days.
