The Affordable Care Act expands Medicaid eligibility to 138% of the federal poverty level and creates health insurance exchanges for individuals and small businesses to purchase insurance. It also establishes regulations on private health plans such as requiring them to cover pre-existing conditions and limiting premium variation. Additionally, the law mandates that most individuals obtain health insurance by 2014 or pay a penalty, while providing subsidies to make coverage more affordable. The Kaiser Family Foundation provides an overview of these key provisions of the Affordable Care Act.
