Exclusive Provider Organization (EPO)
An EPO is a managed care plan where services are covered only if you go to doctors, specialists, or hospitals in the plan’s network — except in an emergency.
EPO's are often compared to Health Maintenance Organizations (HMOs). EPOs are restrictive like HMOs in that they have a limited network of providers.
EPOs are less restrictive than HMOs in that they do not require a primary care physician be selected or a referral to a specialist like HMOs.
