Health care spending rose in 2015 by a 5.5 percent increase over 2014's spending, and that rate of increase is likely to rise in years to come.

That's according to Modern Healthcare, which reported that the U.S. health care system spent $3.2 trillion in 2015, or almost $10,000 for every person, according to the latest federal projections. The rate of increase in 2014 was 5.3 percent, and while a lot of that additional spending is due to more people being insured under the Affordable Care Act, the rate increase is not as high as in previous years.

However, government economists are predicting that health care spending is going to increase by an average of 5.8 percent annually for the next 10 years. And health care occupies more of a share of the economy than it ought, accounting for 17.8 percent of gross domestic product in 2015. That share, estimate actuaries from the Center for Medicare and Medicaid, will rise to 20.1 percent by 2025, thanks to more people aging into Medicare and needing more health care.
