The "plan providers" listed in this site have agreed to provide you with your health care coverage. You will get your routine or basic care from your Primary Care Physician (PCP). The PCP you choose works with certain plan specialists he/she uses for referrals, called a "referral circle", to provide the medical care you need. This means in most cases, you will not have access to the entire Tufts Medicare Preferred HMO network, except in an emergency or urgent care situations, or for out-of-area renal dialysis. If you obtain routine care from out-of-network providers neither Medicare nor Tufts Health Plan Medicare Preferred will be responsible for the costs.
