ACA

The Affordable Care Act (ACA), often called Obamacare, is a U.S. law enacted in 2010 to make health insurance more accessible and affordable. It expanded Medicaid, created health insurance marketplaces, and established rules to prevent insurers from denying coverage due to pre-existing conditions. The ACA also mandates that most Americans have health insurance or face a penalty (though the penalty has been reduced to zero in many states). Overall, it aims to improve healthcare quality, reduce costs, and increase coverage for more Americans.
