What it means
The Affordable Care Act (ACA), signed into law in 2010, is the major US health reform legislation that expanded insurance coverage through multiple mechanisms: the Health Insurance Marketplace with income-based subsidies, Medicaid expansion in participating states, requirements for coverage of pre-existing conditions, prohibition on lifetime and annual benefit limits, extension of dependent coverage to age 26, and requirements for coverage of essential health benefits and preventive services without cost-sharing. The ACA significantly reduced the uninsured rate in the US.
