17.2 The Affordable Care Act: EHBs, Marketplaces, Subsidies, Mandates

The Affordable Care Act Framework

The Affordable Care Act (ACA), enacted in 2010, reshaped the individual and small-group health markets. Its core consumer protections are heavily tested:

• Guaranteed issue: insurers must accept all applicants regardless of health.
• No pre-existing condition exclusions for any enrollee.
• Community rating: premiums may vary only by age (3:1 maximum), tobacco use (1.5:1), geographic area, and individual vs. family — not by health status or gender.
• No lifetime or annual dollar limits on essential health benefits.
• Dependent coverage to age 26 on a parent's plan.
• Preventive services at no cost-sharing when in-network.

These protections apply to non-grandfathered individual and small-group plans.

The ACA also requires a single risk pool within each market, a medical loss ratio (MLR) rule (insurers must spend at least 80% of individual/small-group premium, or 85% in the large-group market, on claims and quality, or issue rebates), and a uniform Summary of Benefits and Coverage (SBC) so consumers can compare plans on the same terms.

Essential Health Benefits (EHBs)

Non-grandfathered individual and small-group plans must cover ten categories of Essential Health Benefits (EHBs):

1. Ambulatory (outpatient) services
2. Emergency services
3. Hospitalization
4. Maternity and newborn care
5. Mental health and substance-use disorder services
6. Prescription drugs
7. Rehabilitative and habilitative services and devices
8. Laboratory services
9. Preventive and wellness services and chronic disease management
10. Pediatric services, including oral and vision care

A frequent trap: adult dental and vision are NOT required EHBs — only pediatric dental and vision are. Plans sold through the Marketplace are categorized by metal tier, which sets the actuarial value (AV) — the share of average costs the plan pays.

Metal Tiers and Actuarial Value

Actuarial value describes the average split across a standard population, not what any one person pays. Cost-sharing reduction (CSR) subsidies are available only on Silver plans, which is why Silver is strategically important for lower-income enrollees.

All non-grandfathered plans must also respect a federal annual out-of-pocket maximum that caps a member's in-network cost-sharing for EHBs each year; once reached, the plan pays 100% of covered EHB costs. A higher actuarial value (Gold or Platinum) means higher premiums but lower cost-sharing — a trade producers explain so clients match the tier to expected utilization rather than premium alone.

Grandfathered Plans and Open Enrollment

Plans that existed before March 23, 2010 and have not made significant benefit cuts are grandfathered and are exempt from some ACA requirements (such as covering all EHBs and offering preventive care with no cost-sharing). Most plans have lost grandfathered status over time.

Individuals enroll during the annual Open Enrollment Period. Outside that window, coverage requires a Special Enrollment Period (SEP) triggered by a qualifying life event — marriage, birth or adoption, loss of other coverage, or a permanent move. Producers must document the qualifying event; a desire to buy after getting sick is not a qualifying event and is a common consumer misunderstanding the exam tests.

Marketplaces, Subsidies, and Mandates

The Health Insurance Marketplace (Exchange) is where individuals shop, compare metal tiers, and apply for financial help. Two subsidy types exist:

• Premium Tax Credit (PTC): an advanceable, refundable credit that lowers monthly premiums; tied to the second-lowest-cost Silver plan (the benchmark) and household income relative to the Federal Poverty Level (FPL).
• Cost-Sharing Reductions (CSRs): lower deductibles, copays, and out-of-pocket maximums for eligible enrollees who choose Silver.

Worked example. A household's expected contribution under the PTC formula is $200/month, and the benchmark Silver premium is $650/month. The advance PTC is $650 − $200 = $450/month. The credit is reconciled on the tax return; if income was higher than estimated, part of the credit may be repaid.

The federal individual mandate penalty was reduced to $0 beginning 2019, though some states impose their own mandate. The employer shared-responsibility mandate still applies to Applicable Large Employers (50+ full-time-equivalent employees), which must offer affordable, minimum-value coverage or face penalties.

Eligibility Limits, Affordability, and Reconciliation

PTC eligibility depends on household MAGI relative to the Federal Poverty Level (FPL) and on not having access to other affordable coverage. Key tested rules:

• An employee with an affordable, minimum-value employer offer is generally ineligible for a Marketplace subsidy.
• Subsidies are advanced monthly based on estimated income, then reconciled on the federal tax return; underestimating income can mean repaying part of the credit.
• CSR plans quietly raise a Silver plan's actuarial value (for example, to 87% or 94%) for the lowest-income enrollees, which is why advisors steer those clients to Silver.

Scenario. A client estimates income that qualifies for a $400/month advance PTC but earns a large bonus mid-year. At tax time the reconciliation shows excess advance credit, and the client must repay some of it — a point producers should disclose so clients estimate income carefully.
