A new study published Monday by The New England Journal of Medicine found 10.3 million people have gained health insurance since the ObamaCare exchanges were launched.
The study, conducted by researchers from the Department of Health and Human Services and Harvard University, found the number of uninsured has fallen from 21 percent in September 2013 to 16.3 percent in April 2014.
The study found states that expanded Medicaid under the healthcare law saw their insurance rates climb higher than states that did not expand the traditional health program for the poor.
States that expanded Medicaid saw a 5.1 percent drop in uninsured poor adults, a point highlighted by Health and Human Services Secretary Sylvia BurwellSylvia Mathews BurwellHHS launches contest to make bills simpler Obama administration takes step to reform Medicare payments Rubio breaks with GOP, backs Obama Zika request MORE.
“To date, 26 states plus D.C. have moved forward with Medicaid expansion,” she said in a statement. “We’re hopeful remaining states will come on board and we look forward to working closely with them.”
The administration says more than 8 million people gained health insurance through either the federal exchange or state-based exchanges. Another 7 million gained insurance because of the expansion of Medicaid, the administration has said.
