Patient Protection and Affordable Care Act

The Patient Protection and Affordable Care Act (PPACA), commonly called the Affordable Care Act (ACA) or, colloquially, Obamacare, is a United States federal statute signed into law by President Barack Obama on March 23, 2010. Together with the Health Care and Education Reconciliation Act amendment, it represents the most significant regulatory overhaul of the U.S. healthcare system since the passage of Medicare and Medicaid in 1965. Under the act, hospitals and primary physicians would transform their practices financially, technologically and clinically to drive better health outcomes, lower costs and improve their methods of distribution and accessibility.

The ACA was enacted to increase the quality and affordability of health insurance, lower the uninsured rate by expanding public and private insurance coverage, and reduce the costs of healthcare for individuals and the government. It introduced mechanisms like mandates, subsidies, and insurance exchanges. The law requires insurance companies to cover all applicants within new minimum standards and offer the same rates regardless of pre-existing conditions or sex. In 2011, the Congressional Budget Office projected that the ACA would lower both future deficits and Medicare spending.
