U.S Health Care Spending Could be Trillions Less Than Expected Over 5 Years: Study

Health care spending in the United States could be $2.6 trillion less over five years than originally projected after the Affordable Care Act was passed, an Urban Institute study says.

It said growth in health care spending appeared to slow after it spiked in 2014, CNBC reported.

It’s not clear if the Affordable Care Act is the reason for the 11 percent drop in projected health care spending between 2014 and 2019, or whether it’s the weak economy, according to the study.

It said if the Affordable Care Act is the reason for the savings, “then slower growth [in national health spending] may persist beyond current projections,” CNBC reported.
