The Affordable Care Act (ACA) extends health insurance coverage to people who lack access to an affordable coverage option. Under the ACA, as of 2014, Medicaid coverage is extended to low-income adults in states that have opted to expand eligibility, and tax credits are available for middle-income people who purchase coverage through a health insurance Marketplace. Millions of people have enrolled in these new coverage options, but millions of others are still uninsured. Some remain ineligible for coverage, and others may be unaware of the availability of new coverage options or still find coverage unaffordable even with financial assistance.
