An Exclusive Provider Organization (EPO) is a health insurance plan that covers care only from providers within its network. EPO plans don't require a referral to see a specialist, and they're available on the Health Insurance Marketplace in Bronze, Silver, Gold and Platinum tiers, per HealthCare.gov's plan type definitions.
But EPO coverage stops at the network boundary for non-emergency care. If an EPO member sees an out-of-network provider, the plan pays nothing and the member covers the full cost. EPO plans work best for policyholders in areas with large, accessible provider networks.
