The Patient and Protection Affordable Care Act (ACA) is signed into law on March 23rd. The most sweeping health care reform the U.S. had seen in decades, the ACA sought to dramatically increase access to health insurance for those without employer-sponsored care, to expand access to Medicaid for low-income Americans, and to encourage states to develop and explore innovative medical care delivery methods designed to lower the cost, and improve the quality, of health care.
