Lindsey Leininger and colleagues analyzed data on Medicaid/BadgerCare Plus applications in Wisconsin submitted between January 2008 and November 2009. They found that 62% of applications were submitted through ACCESS, the state's online portal. Applicants using ACCESS were less likely to be determined eligible for coverage (69%) compared to other methods. ACCESS attracted applicants with lower socioeconomic status at higher rates. The portal also increased rates of spillover applications to other programs but eligibility rates for these spillover applications were lower than for other methods. Wisconsin aims to expand ACCESS for future health insurance exchanges.
