Essential health benefits: the ten categories, and what "covered" still leaves open

Shopping for marketplace coverage gets easier once you know which questions the law has already answered. One of them is what the plan has to cover at all.

The ten categories

Plans sold through the Marketplace cover a set of essential health benefits. The categories are fixed in federal regulation at 45 CFR §156.110:

• Ambulatory patient services — outpatient care you get without being admitted
• 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

HealthCare.gov's own summary of what Marketplace plans cover walks the same list in consumer language, and adds the other pieces that ride along with it — coverage regardless of pre-existing conditions, and no annual or lifetime dollar limits on these benefits.

Where the specifics come from

The categories are federal; the detail underneath them is not uniform. Each state has a benchmark plan that fills in what the categories mean in practice — how many visits of a given therapy, which devices, how a drug class is handled. That is why two plans in different states can both cover “rehabilitative services” and describe the benefit differently. It is also why the plan document, not the category list, is the place to check a specific need.

What the list doesn't decide

Three things sit outside it, and they are usually the three that determine your experience of the plan.

What you pay. Covered does not mean free. The metal tier — bronze, silver, gold, platinum — describes how the plan splits the cost of covered care with you, which we walked through in metal tiers and the silver rule. The one systematic exception is preventive care: in-network preventive services are covered without cost sharing, even before a deductible is met.

Where it's covered. The category list says nothing about networks. Whether your doctor is in network, and whether you need a referral to see a specialist, is the plan type — a separate axis we covered in HMO, PPO, EPO, POS.

Which drug, specifically. Prescription drugs is a category; the formulary is the list. Two plans can both cover the category and place your particular prescription on different tiers, or handle it under different rules.

The adult dental footnote

Pediatric dental and vision are inside the ten categories. Adult dental is not. HealthCare.gov explains how dental coverage is handled in the Marketplace — as part of a health plan or as a separate dental plan — and the distinction between children's and adults' coverage is the part most people find surprising.

Coverage that isn't marketplace coverage

The ten categories apply to Marketplace plans. Products that sit outside that framework — fixed indemnity plans, accident and critical-illness plans, and other limited-benefit coverage — are not built to that standard and are not designed to replace it. That is a real distinction rather than a fine-print one, and we treated it directly in what fixed indemnity is and isn't.

If you want to know whether a specific plan covers a specific thing you rely on — a medication, a therapy, a specialist — that is a plan-document question rather than a category question, and a licensed agent can look it up with you at no cost and with no pressure.
