In Wisconsin, the Medicaid program is known as BadgerCare. It costs about $4.6 billion, covering about 782,000 people — mostly children.

Rather than accepting the Medicaid expansion funds, which would have covered costs for coverage of people earning up to 138 percent of the poverty level, Walker tightened up the program by lowering eligibility from 200 percent of the poverty level to 100 percent.

The changes allowed at least 97,000 childless adults who had been on a waiting list for coverage to receive it, but kicked about 63,000 people off the program.

The state could have saved about $206 million in the 2013-15 budget by accepting the expansion, according to a memo from the nonpartisan Legislative Fiscal Bureau. That's more than originally estimated, because more childless adults have signed up than expected.
