Impact of the Affordable Care Act on Health Insurance

For students preparing for the practice Accident & Health questions, understanding the transformation of the insurance landscape under federal reform is essential. The legislation introduced standardized requirements that removed many of the traditional barriers to obtaining health coverage, shifting the industry from a medical underwriting model to a guaranteed issue model.

Before these federal standards, insurance companies frequently used individual medical histories to determine eligibility or set premium rates. Under the current framework, insurers are prohibited from denying coverage or charging higher premiums based on pre-existing conditions. This shift ensures that all individuals have access to a baseline level of care regardless of their health status at the time of application. For a broader look at how this fits into the industry, refer to our complete Accident & Health exam guide.

One of the most significant impacts of the legislation was the mandate that all individual and small group health insurance plans must provide coverage for a specific set of benefits. These are known as Essential Health Benefits (EHBs). These benefits ensure that every policyholder has access to comprehensive care across several categories.

The ten categories of Essential Health Benefits include:

• Ambulatory patient services: Outpatient care provided without being admitted to a hospital.
• Emergency services: Care for life-threatening conditions, which cannot require prior authorization.
• Hospitalization: Inpatient care, including surgeries and overnight stays.
• Maternity and newborn care: Care provided before and after a baby is born.
• Mental health and substance use disorder services: Including behavioral health treatment, counseling, and psychotherapy.
• Prescription drugs: Coverage for medications required to treat illnesses or conditions.
• Rehabilitative and habilitative services: Services and devices to help people with injuries or disabilities recover or gain skills.
• Laboratory services: Testing required for diagnosis or treatment monitoring.
• Preventive and wellness services: Chronic disease management and screenings (often provided at no cost-sharing).
• Pediatric services: Including oral and vision care for children.

To help consumers compare plans, the law established four "Metal Tiers" based on actuarial value. The actuarial value represents the percentage of total average costs for covered benefits that the plan will pay. It is important to note that these tiers do not reflect the quality of medical care, but rather how the insurer and the insured share the costs.

• Bronze: The plan pays approximately 60%, and the insured pays 40%. These plans typically have the lowest premiums but the highest out-of-pocket costs.
• Silver: The plan pays 70%, and the insured pays 30%. This is the only tier where individuals may qualify for Cost-Sharing Reductions (CSRs).
• Gold: The plan pays 80%, and the insured pays 20%. These plans have higher premiums but lower deductibles.
• Platinum: The plan pays 90%, and the insured pays 10%. These plans have the highest premiums and the lowest out-of-pocket costs for the consumer.
