15.1 ACA Essential Health Benefits and Metal Levels

The Affordable Care Act (ACA) standardized what a qualified individual or small-group health plan must cover. Before 2014, an individual policy could omit maternity care, prescription drugs, or mental-health treatment. The ACA replaced that patchwork with a federally defined floor called Essential Health Benefits (EHBs).

A plan that covers all required EHBs and meets the consumer-protection rules is a qualified health plan (QHP) when sold on a Marketplace. Producers must understand that EHBs are a coverage floor, not a ceiling: insurers may add benefits but may not drop any of the ten categories.

The Ten Essential Health Benefit Categories

Non-grandfathered individual and small-group plans (whether sold on or off the Marketplace) must cover all ten EHB categories.

Exam trap: EHB rules apply to individual and small-group plans. Large-group and self-funded (ERISA) plans are NOT required to cover the full EHB package, though if they do cover an EHB they cannot impose annual or lifetime dollar limits on it.

Each state selects a benchmark plan that defines the precise services within each EHB category, so the exact covered drug list or therapy-visit count can vary by state. What never varies is that all ten categories must be present. A producer who tells a client a plan "doesn't include mental-health coverage" is describing a non-compliant or grandfathered product, not a current qualified health plan.

The ACA also folded in earlier reforms that remain heavily tested. Dependent children may stay on a parent's plan until age 26 regardless of marital, student, or financial status. Insurers may not rescind coverage except for fraud or intentional misrepresentation, and they must provide a plain-language Summary of Benefits and Coverage (SBC) so consumers can compare plans on a standardized form.

No Dollar Limits on Essential Benefits

The ACA prohibits both annual and lifetime dollar limits on EHBs. An insurer can still limit the number of covered visits (for example, 30 physical-therapy sessions per year), but it cannot cap the dollar value of an EHB.

First-Dollar Preventive Care

Preventive services that the U.S. Preventive Services Task Force (USPSTF) rates A or B must be covered at 100% with no cost-sharing when delivered in-network — no deductible, copay, or coinsurance. This category includes immunizations, recommended cancer screenings (mammograms, colorectal), blood-pressure and cholesterol screening, and well-woman visits.

Worked example: A Silver plan has a $3,000 deductible. A member gets an in-network screening colonoscopy (a USPSTF grade-A service). The member pays $0, because grade A/B preventive care is exempt from the deductible. Had the colonoscopy been diagnostic (to investigate symptoms), normal cost-sharing would apply.

Metal Levels and Actuarial Value

The ACA groups Marketplace plans into four metal levels. The metal level does not change which benefits are covered — every metal plan covers the same ten EHBs. Instead, it describes actuarial value (AV): the average share of covered medical costs the plan is expected to pay for a standard population.

Each AV is allowed a de minimis variation, generally plus or minus 2 percentage points, so a Silver plan can range roughly 68%–72% AV.

Reading the Premium/Cost-Sharing Trade-Off

• Bronze: low monthly premium, high deductible. Best for healthy people who want catastrophic protection.
• Platinum: high premium, low out-of-pocket costs. Best for members who expect heavy utilization.
• Silver: the benchmark tier — the only tier where cost-sharing reductions (CSRs) apply (covered in 15.3).

Worked example: Two members each incur $10,000 of covered, in-network claims after meeting plan rules. On a Bronze plan (60% AV) the carrier pays roughly $6,000; on a Platinum plan (90% AV) it pays roughly $9,000. AV is a population average, not a guarantee for any one claim.

Catastrophic Plans

A fifth, separate category — the catastrophic plan — sits below Bronze. It carries a very low premium, a deductible equal to the annual out-of-pocket maximum, and covers three primary-care visits plus all USPSTF preventive services before the deductible.

Eligibility is restricted:

• Enrollees under age 30, OR
• Anyone with a hardship or affordability exemption.

Catastrophic plans are not eligible for premium tax credits and CSRs do not apply. They are designed as a true safety-net product, not a subsidized coverage option.

Grandfathered vs. Grandmothered Plans

• Grandfathered plans existed on March 23, 2010, and have not made significant changes; they are exempt from some ACA mandates (such as the full EHB package) but must still cover dependents to age 26 and cannot impose lifetime limits on covered EHBs.
• Grandmothered (transitional) plans were issued after the ACA but before 2014 and have been allowed to continue under federal transitional relief in many states.

Exam trap: Candidates confuse "metal level" with "benefit richness." A Gold plan does not cover more services than a Bronze plan — both cover the same EHBs. Gold simply pays a higher share of the cost (higher actuarial value).

When advising a client, weigh expected utilization against cash flow. A young, healthy client with stable income and an emergency fund is often well served by Bronze: the low premium is a near-certain saving, and the high deductible only bites in a bad year. A client managing a chronic condition with frequent specialist visits and ongoing prescriptions usually saves money overall on Gold or Platinum, where predictable copays replace large deductible exposure.

Actuarial value should never be read as a personal guarantee. A 70% Silver plan does not pay 70% of your next claim — it pays 70% of total covered costs across a standard population. An individual's real share depends on the specific deductible, copay, and coinsurance structure and on how much care that person actually uses during the year.
