10.3% (over 4.7 million) of adults with a mental illness remain uninsured.
Under the Affordable Care Act (ACA), the U.S. continues to see a decline in Americans who are uninsured. There was a 1.9 percent reduction from last year’s dataset.
Thirty-nine states saw a reduction in Adults with AMI who are uninsured. The largest reductions were seen in Louisiana (5.3%), New York (4.7%), Iowa (4.6%) and Arkansas (4.2%).
Each of the bottom 17 states, with the exception of Louisiana, are states that have not expanded Medicaid. Louisiana, however, has had the largest reductions in the rate of uninsured adults with AMI since the state expanded Medicaid in 2016, from 20 percent of adults with AMI to 14.7%.
The rankings for this indicator used data from the 2016-2017 NSDUH. Some states, such as Arkansas, that had a reduction in uninsured adults with AMI passed Medicaid work requirements in 2018, which may lead to a large change in coverage in future reports.
The state prevalence of uninsured adults with mental illness ranges from 2.4% in Massachusetts to 22.9% in Wyoming.
