In the United States, essential health benefits (EHBs) are a set of ten benefits, defined under the Affordable Care Act (ACA) of 2010, that must be covered by individually-purchased health insurance and plans in small-group markets both inside and outside of health insurance marketplaces. Large-group health plans, self-insured ERISA plans, and ERISA-governed multi-employer welfare arrangements that are not subject to state insurance law are exempted from the requirement.
