Essential Health Benefits

Essential health benefits, or EHBs, are a set of 10 categories of services that certain health plans must cover under the Affordable Care Act. HealthCare.gov describes them as categories of services that health insurance plans must cover, with each state's benchmark plan filling in the details.

For HR teams, EHBs matter because they shape the baseline benefits in the individual and small group markets, and they limit what large and self-funded plans can do with the services they choose to cover.

What Are the 10 Essential Health Benefits?

The Affordable Care Act lists ten categories that covered plans must include:

• Ambulatory patient services, such as outpatient visits.
• Emergency services.
• Hospitalization.
• Maternity and newborn care.
• Mental health and substance use disorder services, including behavioral health treatment.
• Prescription drugs.
• Rehabilitative and habilitative services and devices.
• Laboratory services.
• Preventive and wellness services and chronic disease management.
• Pediatric services, including oral and vision care.

Which Plans Must Cover Essential Health Benefits?

The requirement applies to non-grandfathered health insurance sold in the individual and small group markets, both on and off the marketplace. Each state's benchmark plan defines what is covered within each category.

Large group plans and self-funded plans are not required to cover EHBs as a set. That is why a large employer's plan can look different from a small group plan sold in the same state.

Children's dental coverage is a common point of confusion. HealthCare.gov notes that plans must offer dental coverage for children, while dental benefits for adults are optional.

How Do EHBs Affect Large and Self-Funded Employers?

Even when a plan is not required to cover EHBs, the ACA still limits how it treats them. A large or self-funded plan that does cover an essential health benefit generally cannot impose annual or lifetime dollar limits on it.

Out-of-pocket maximums also apply to in-network essential health benefits across group health plans. Employers use the EHB categories as the reference list when they review whether a limit or exclusion is permitted.

In practice, HR and brokers often point to the benchmark plan when explaining why a certain service is covered. It is a useful yardstick even where it is not binding.

How Are EHBs Different From Preventive Care and Voluntary Benefits?

Preventive services form one of the ten EHB categories, but the ACA also requires most plans to cover many preventive services without cost sharing. That no-cost rule is separate from the EHB list and reaches a wider set of plans.

Voluntary benefits such as accident, critical illness or dental riders sit outside the EHB framework. They are optional additions and appear in the employer's fringe benefits mix, not as the core medical plan.

Keeping these ideas apart makes employee communication clearer. EHBs describe what a qualifying medical plan covers, and voluntary benefits describe optional extras.

How Should Employers Use EHBs in Plan Reviews?

Treat the EHB list as a checklist during plan review. When a vendor proposes exclusions, caps or visit limits, compare them against the ten categories and ask whether the change would place a dollar limit on a covered essential benefit.

Ask the broker which state benchmark plan applies if the employer buys insured coverage in the small group market, and whether any categories are carved out through a separate vendor, such as a pharmacy benefit manager or a behavioral health carve-out.

Record the answers in the plan file. When employees ask why a service is or is not covered, HR can respond with specifics instead of guesses.

How Can HR Cloud Help Explain Coverage to Employees?

HR Cloud's product pages do not cover plan design or EHB mapping. People HRIS offers a self-service HRIS, secure document storage with version tracking and workflows, which HR can use to publish plan documents and keep them current.

Frequently Asked Questions

Q: Who decides what each EHB category includes?

A: Each state selects a benchmark plan, and that plan defines the services covered within each category for individual and small group coverage.

Q: Do self-funded plans have to cover EHBs?

A: No, not as a set. If they cover an essential health benefit, they generally cannot apply annual or lifetime dollar limits to it.

Q: Are EHBs the same as preventive care?

A: No. Preventive care is one of the ten categories, and a separate rule requires many preventive services to be covered without cost sharing.

Q: Is adult dental an essential health benefit?

A: No. Pediatric dental is part of the pediatric services category, and dental benefits for adults are optional.

Q: Do grandfathered plans have to cover EHBs?

A: No. Grandfathered individual and small group plans are exempt from the EHB requirement, though other ACA rules still apply.

Q: Why should HR care about EHBs?

A: They set the reference list that tells employers which services cannot be subject to annual or lifetime dollar limits, and they help explain why plan coverage differs by market.
