The ACA includes health-related provisions, most of which took effect in 2014, including expanding Medicaid eligibility for people making up to 133 percent of the federal poverty level (FPL) starting in 2014,[305] subsidizing insurance premiums for people making up to 400 percent of the FPL ($88,000 for family of four in 2010) so their maximum "out-of-pocket" payment for annual premiums will be from 2 percent to 9.5 percent of income,[306] providing incentives for businesses to provide health care benefits, prohibiting denial of coverage and denial of claims based on pre-existing conditions, establishing health insurance exchanges, prohibiting annual coverage caps, and support for medical research. According to White House and CBO figures, the maximum share of income that enrollees would have to pay would vary depending on their income relative to the federal poverty level.
