Health Care for America Now (HCAN) is a progressive political coalition of more than 1,000 organizations that joined together in 2008 in a successful effort to promote legislation to reform the United States health care system and extend medical benefits to most of the population that is currently uninsured. The Patient Protection and Affordable Care Act (PPACA or ACA) was signed into law by President Barack Obama on March 23, 2010, and HCAN was credited with being a "major contributor" to its passage. After enactment of the law, HCAN shifted its activities to defending the law from opposition attacks and advocating for the law before Congress and federal and state regulatory agencies.
