In 2015, Indiana expanded eligibility for Medicaid under the Affordable Care Act (ACA) through a unique waiver, Healthy Indiana Plan 2.0, which requires enrollees to make monthly contributions to an account that is similar to a health savings account to receive full benefits. Enrollees who fail to make these contributions receive less generous benefits if their income is below the federal poverty level, and if it is 100-138 percent of poverty, they are locked out of coverage for six months.We estimated the impact of this expansion on coverage rates and compared the effects to results from other states that expanded Medicaid after 2014. We found that Indiana's coverage gains (relative to pre-ACA uninsurance rates) were smaller than gains in neighboring expansion states, but larger than those in other states. These results imply that while one potential reason for Indiana's lower gains relative to neighboring states was its cost-sharing requirements, expansion led to unquestionable coverage gains in the state.
