The estimated total amount of uncompensated costs incurred by hospitals in 2014 was $27.3 billion, which is $7.4 billion, or 21 percent, less than uncompensated hospital care would have been in 2014 at 2013 levels, before Accountable Care Act Medicaid coverage provisions took effect. Federal data reported by CNBC on March 23 indicate most of the reduction came in the 28 states and the District of Columbia that expanded their Medicare programs under the act to cover nearly all poor people in their states, while those that did not could have seen their revenues decline by an additional $1.4 billion.
