In January 2012, Walker returned a $37.6 million federal grant meant to set up a health exchange in Wisconsin for the Patient Protection and Affordable Care Act. Walker said "Stopping the encroachment of Obamacare in our state, which has the potential to have a devastating impact on Wisconsin's economy, is a top priority." Walker rejected an $11 million federal grant designed to improve Medicaid enrollment systems. It can take up to 3 months to determine whether an applicant qualifies for the program. If the applicant does not qualify, the state must pay the medical costs for the first three months. The Walker administration previously said it wants to end the practice of presuming some applicants are eligible and go to a real-time system for determining eligibility. Walker rejected an expansion of Medicaid coverage for the state, but instead reduced the eligibility requirements for the state's BadgerCare program.
