Premiums for low-cost medical plans could go up an average of 11 percent next year, according to a new study done on ObamaCare.
About 12 million people get private coverage through HealthCare.gov and online insurance markets operated by states, like Sooner Care.
A new Kaiser Family Foundation study predicts many of those people will be paying a lot more next year.
The study looked at data from 14 metro areas around the country.
It found premiums for the lowest cost silver plan will go up in 12 of those 14 areas.
Half of the cities will see increases of 10 percent or more.
Last year, only two of the cities had double digit increases.
The lead author of the study said premiums are going up faster for 2017 than they have in past years.
The impact on consumers will depend on whether they get government subsidies for their premiums, as well as whether they're willing to switch plans.
