An EPO, or Exclusive Provider Organization, is a health insurance plan that covers care only from doctors and hospitals inside its approved network. EPO plans don't require a referral to see a specialist, which sets them apart from HMO plans.
EPO plans give you direct access to in-network specialists without routing through a primary care doctor, which works well for people who already know what type of specialist they need or see the same providers regularly. Coverage averages $676 monthly for a Silver-tier plan, per MoneyGeek's 2026 analysis of 4,639 individual marketplace plans.
One firm limit applies to every EPO: the plan pays nothing for out-of-network care outside emergencies. If your doctor leaves the network mid-year, you pay the full cost of any visit until you switch to an in-network provider.
