15.1 ACA Essential Health Benefits and Metal Levels

Essential Health Benefits (EHB)

The Affordable Care Act (ACA) requires every individual and small-group plan sold on or off the Marketplace to cover a defined package of Essential Health Benefits (EHB). The package is built from ten statutory categories, and a plan cannot impose annual or lifetime dollar limits on any EHB. This is one of the most heavily tested concepts on the national Life & Health exam, so memorize the ten categories cold.

The Ten Essential Health Benefit Categories

A common exam trap: adult dental and adult vision are NOT Essential Health Benefits. Only pediatric oral and vision care are required. Cosmetic surgery, long-term custodial care, and most adult dental services fall outside the EHB package. Preventive services in category 9 must be covered with zero cost sharing — no deductible, copay, or coinsurance applies to in-network preventive care such as immunizations, well-woman visits, and recommended cancer screenings.

Metal Levels and Actuarial Value

Non-grandfathered individual and small-group plans are organized into four metal levels plus a limited catastrophic tier. Metal levels are defined by actuarial value (AV) — the percentage of total covered medical costs the plan is expected to pay for a standard population. The metal level does NOT describe the quality of care or the breadth of the EHB package (all metal plans cover the same ten EHBs); it describes only how cost sharing is split between the plan and the insured.

Metal Tiers by Actuarial Value

There is an allowable de minimis variation (generally plus or minus 2 percentage points) around each target AV. Remember the inverse relationship: higher metal level = higher premium but lower out-of-pocket cost when care is used. A healthy consumer who rarely uses care may prefer Bronze; a consumer expecting heavy utilization may prefer Gold or Platinum.

Worked Example: Actuarial Value

Suppose a standard population is projected to incur $10,000 in total covered medical costs in a year. Under a Silver plan with a 70% AV, the insurer is expected to pay 70% × $10,000 = $7,000, and the standard population pays the remaining $3,000 through deductibles, copays, and coinsurance. Under a Bronze plan (60% AV), the insurer pays only $6,000 and the insured population pays $4,000. AV is a population-wide actuarial estimate — it does not promise any single insured that exactly 70% of their bills will be paid.

The Catastrophic Plan

A fifth option, the catastrophic plan, is available only to people under age 30 or those who qualify for a hardship or affordability exemption. Catastrophic plans carry very low premiums and very high deductibles (the deductible equals the annual out-of-pocket maximum), but they still cover all ten EHBs, at least three primary-care visits per year before the deductible, and free preventive services. A critical exam point: premium tax credits cannot be applied to catastrophic plans.

Annual Out-of-Pocket Maximum

Every non-grandfathered plan must cap the insured's annual out-of-pocket maximum (MOOP) for in-network EHBs. Once combined deductible, copays, and coinsurance reach this cap in a plan year, the plan pays 100% of covered in-network EHBs for the rest of the year. Premiums do not count toward the MOOP, and out-of-network charges and non-EHB services generally do not count either. The federal limit is indexed annually; the MOOP is a hard ceiling protecting against catastrophic medical debt, which is the core consumer protection the ACA was built to provide.

Why Metal Levels Matter to the Producer

When advising a client, a producer balances premium against expected utilization. A young, healthy client with few prescriptions and rare doctor visits often saves money on a Bronze plan despite its high deductible, because the lower premium outweighs occasional out-of-pocket costs. A client managing a chronic condition, expecting surgery, or taking expensive specialty drugs usually comes out ahead on Gold or Platinum, where richer cost sharing offsets the higher premium. Suitability discussions should document the client's anticipated needs, network preferences, and prescription list.

Reasoning About Metal Levels and EHBs

ACA questions reward you for connecting the ten essential health benefits to the metal-level actuarial values, not for memorizing premiums. Every non-grandfathered individual and small-group plan must cover the ten EHB categories — ambulatory, emergency, hospitalization, maternity and newborn, mental health and substance-use, prescription drugs, rehabilitative and habilitative services, laboratory, preventive and wellness, and pediatric services including dental and vision — with no annual or lifetime dollar limits on essential benefits and free in-network preventive care.

The metal levels describe the share of costs the plan pays on average: Bronze about 60 percent, Silver 70, Gold 80, and Platinum 90, with the member paying the remainder through deductibles, copays, and coinsurance up to the annual out-of-pocket maximum. Higher metal tiers carry higher premiums but lower cost-sharing, so the suitable choice depends on expected utilization.

Exam Trap: Cost-sharing reductions attach only to Silver plans. A subsidy-eligible client who picks Bronze for the lower premium forfeits the CSR benefit, so suitability discussions should document the client's needs, network preferences, and prescription list before choosing a tier.
