Michigan has received a federal waiver that ensures 600,000 low-income adults will continue qualifying for Medicaid insurance.
The expanded program would have ended next spring without the approved waiver, which was announced Thursday by Gov. Rick Snyder.
A state law establishing Healthy Michigan required the state to get a second waiver from the Obama administration or the program launched in 2014 would have gone away on April 30.
Under the waiver, roughly 100,000 adults with incomes between 100 and 133 percent of the poverty line who have been enrolled for four years must attest to a healthy behavior or pay higher copays and contribute more to health savings accounts.
Those not demonstrating a healthy behavior will have to buy private insurance through the federal health insurance marketplace.
