As Wisconsin considers increasing premiums in its Medicaid program,BadgerCare Plus, CCF researchers examined the impact of premiums on families in Wisconsin’s Medicaid program. In this policy brief, they look at the effect on participation in the program if premiums were increased or added for families between 100 and 200% of the FPL in BadgerCare Plus at 3% and 4% of family income. Findings in the report suggest that such an increase will lead to sharp declines in children and families enrolling in coverage, adverse selection and possible increases in the use of the emergency room for routine care.
