<P> The ACA includes provisions to take effect between 2010 and 2020 , although most took effect on January 1 , 2014 . Few areas of the US health care system were left untouched , making it the most sweeping health care reform since the enactment of Medicare and Medicaid in 1965 . However , some areas were more affected than others . The individual insurance market was radically overhauled , and many of the law 's regulations applied specifically to this market , while the structure of Medicare , Medicaid , and the employer market were largely retained . Most of the coverage gains were made through the expansion of Medicaid , and the biggest cost savings were made in Medicare . Some regulations applied to the employer market , and the law also made delivery system changes that affected most of the health care system . Not all provisions took full effect . Some were made discretionary , some were deferred , and others were repealed before implementation . </P>
