Health insurance premiums for the first Obamacare open enrollment under President Trump will be 37 percent higher than last year for mid-level plans sold on healthcare.gov, according to a new report by the Department of Health and Human Services.

Healthcare.gov is the website created by the federal government that 38 states use to sell Obamacare coverage during the open enrollment period, which runs this year from Nov. 1 to Dec. 15. People who buy these plans do not receive health insurance through work or through a government program, and roughly 6 percent of people in the U.S. get coverage this way.
