What you need to know. An exclusive provider organization, or EPO, is a health insurance plan that is often described as a hybrid between HMOs and PPOs. Like an HMO, EPO plans do not cover out-of-network health care providers. You will not be reimbursed for health care services you get at an out-of-network provider. Like a PPO, EPO plans do not require that you get a referral from your primary care physician in order to see a specialist.
