The Affordable Care Act refers to the 2010 healthcare reform law that aims to improve the healthcare system in the United States. It does this by improving access to health coverage and increasing consumer protections in the health insurance markets. It is based on a market model (not a government model) of healthcare. President Obama signed it into law on March 23, 2010. It is in the process of being implemented, and many provisions have already taken effect.
