Essential Health Benefits

Essential health benefits are 10 categories of healthcare services that all ACA-compliant health insurance plans must cover, including hospitalization, prescription drugs, maternity care, mental health, and preventive services.

What Are Essential Health Benefits?

The ACA requires all marketplace and ACA-compliant private plans to cover 10 categories of essential health benefits (EHBs). These are the minimum services every plan must include — you cannot buy an ACA-compliant plan that excludes any of them.

The 10 Essential Health Benefit Categories

  1. Ambulatory services (outpatient care — doctor visits, outpatient surgery)
  2. Emergency services (ER visits — covered at in-network rates even out-of-network)
  3. Hospitalization (inpatient care, surgery, overnight stays)
  4. Maternity and newborn care (prenatal, delivery, postnatal)
  5. Mental health and substance use disorder services (therapy, counseling, rehab)
  6. Prescription drugs (at least one drug in every category)
  7. Rehabilitative services and devices (physical therapy, speech therapy, medical equipment)
  8. Laboratory services (blood tests, diagnostic imaging)
  9. Preventive and wellness services (checkups, vaccinations, screenings — all at $0)
  10. Pediatric services (including dental and vision for children)

What Non-ACA Plans May Exclude

Short-term health insurance, fixed indemnity plans, and supplemental plans are not required to cover essential health benefits. Common exclusions on non-ACA plans:

  • Maternity care
  • Mental health and substance abuse treatment
  • Prescription drug coverage (or very limited)
  • Preventive care at $0
  • Pre-existing conditions

Key distinction: Private ACA-compliant plans purchased directly from carriers (off-marketplace) include all 10 essential health benefits — same as marketplace plans. Only non-ACA plans like short-term insurance can exclude them. This is one of the most important differences when comparing your options.
