Which of the following best describes how an EPO (Exclusive Provider Organization) works?

An EPO combines features of both HMOs and PPOs in a specific way. Like an HMO, an EPO provides no coverage for out-of-network care except in genuine emergencies. But like a PPO, an EPO does not require you to designate a primary care physician or obtain referrals before seeing a specialist. EPOs typically offer lower premiums than PPOs in exchange for the strict network-only requirement. They are a good option for people who do not anticipate needing out-of-network providers but want the flexibility to self-refer to specialists.
