EPO insurance is a newer variant on older health care plans that combines aspects of more-common HMO and PPO insurance. EPO stands for "exclusive provider organization."
Exclusive provider organizations, or EPOs, provide a health insurance option that falls in between HMOs and PPOs in terms of price and access to health care services. It is lesser known than the other two options, but it also may be less expensive for those who are not turned off by some of the restrictions. It is considered a subset of preferred provider organizations, but it does not include reduced fees for out-of-network care.
