ACA (Affordable Care Act)
ACA（医療費負担適正化法） (ACA (iryōhi futankin tekisei-ka hō))
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.
The ACA's individual mandate (penalty for not having insurance) was effectively eliminated in 2019, but its other coverage provisions remain in effect.
