What Are Essential Health Benefits?
Essential health benefits, or EHB, are categories of health care services that many Affordable Care Act-compliant plans must cover. They apply to plans in the individual and small group markets, including Marketplace plans.
EHB rules are meant to keep coverage from excluding entire core categories of care. The exact covered services, limits, and cost sharing can still vary by state benchmark plan and by the specific insurance policy.
Key Takeaways
- Essential health benefits are required categories of coverage for many individual and small group plans.
- They include broad categories such as emergency services, hospitalization, prescription drugs, and preventive care.
- Coverage details can vary by state and plan.
- EHB rules do not mean every service is free or covered without limits.
The Ten Benefit Categories
ACA rules identify ten broad EHB categories. Plans can still use networks, formularies, medical necessity rules, prior authorization, deductibles, copays, and coinsurance.
Category | Examples |
|---|---|
Ambulatory and emergency care | Doctor visits and emergency services. |
Hospital and maternity care | Hospitalization, pregnancy, and newborn care. |
Mental health and substance use | Behavioral health treatment and related services. |
Prescription drugs | Covered medications under the plan formulary. |
Preventive and pediatric services | Preventive care and pediatric oral and vision coverage. |
Where It Affects Coverage
EHB rules affect plan design, annual and lifetime dollar limits, and how consumers compare health plans. If a service falls within an EHB category, federal and state rules may shape how plans cover it.
Large employer plans and self-insured plans are not required to cover all EHB categories in the same way, but other ACA rules may still apply.
What to Check
Review the Summary of Benefits and Coverage, provider network, drug formulary, prior authorization rules, and cost-sharing details. EHB status answers whether a category must be covered, not exactly what the member will pay.
The Bottom Line
Essential health benefits set a coverage floor for many health plans. They make coverage more complete, but the plan documents still determine access, limits, and out-of-pocket cost.
