Medicaid Work Requirements: What Research Shows About Effects on Coverage and Health

Medicaid work requirements, formally called community engagement requirements, have been one of the most contentious healthcare policy debates in the United States over the past decade. Several states received federal approval to require that Medicaid recipients demonstrate employment, job training, volunteering, or other specified activities as a condition of maintaining coverage, with Arkansas being the first state to implement such requirements in 2018. Research on the effects of Arkansas's program, which was blocked by courts before operating for a full year, produced findings that have shaped subsequent policy debates and legal proceedings. The policy rationale for Medicaid work requirements draws on arguments used in welfare reform: that conditioning benefits on work promotes employment, self-sufficiency, and economic mobility among recipients, and that work has intrinsic benefits beyond income including structure, social connection, and sense of purpose. Proponents argue that many Medicaid recipients are able to work and that work requirements provide an appropriate incentive for employment while directing program resources toward those with the most genuine need. Research on Medicaid recipients' employment status challenges a foundational assumption of this argument. Studies of Medicaid recipient demographics consistently find that the large majority of non-elderly, non-disabled adult Medicaid recipients who could work do work, or have reasons they cannot, including caregiving responsibilities, chronic health conditions, school enrollment, or inability to find work. Research using data from the Current Population Survey and state administrative records finds that approximately 63 percent of non-elderly, non-disabled Medicaid enrollees who are not working report that they cannot because they are ill, disabled, or caring for a family member, and the majority of the remaining group who are not working report being enrolled in school or being unable to find employment. The Arkansas program, which required most non-elderly adult Medicaid recipients to document 80 hours per month of qualifying activities including work, job search, job training, volunteering, or education, was studied by researchers who compared coverage and employment outcomes before and after implementation using administrative data and surveys. Research published in the New England Journal of Medicine found that the Arkansas requirement was associated with a significant reduction in Medicaid enrollment, losing approximately 18,000 people their coverage in the months following implementation, without a corresponding increase in employment. The people who lost coverage were predominantly those who had difficulty navigating the reporting requirements, not those who had been working and became ineligible. The disenrollment pattern documented in the Arkansas research reflects what researchers call administrative burden, the time, effort, and knowledge required to complete bureaucratic requirements for benefit retention. Research on administrative burden in public benefit programs finds that it functions as a de facto eligibility restriction that disproportionately affects individuals with lower education, limited internet access, language barriers, cognitive challenges, and unstable living situations. The reporting requirements were primarily online, which excluded individuals without internet access at home or adequate digital literacy. Health consequences of losing Medicaid coverage have been studied in other research contexts. Loss of Medicaid coverage is associated with reduced access to healthcare, higher rates of foregone care due to cost, and in some studies worse health outcomes. Research on the specific health effects of the Arkansas disenrollments is limited by the short duration of the program before court injunction, but the documented loss of coverage for individuals with chronic conditions, mental health needs, and disabilities is clinically concerning. Court decisions have blocked work requirement waivers in Arkansas and other states, with federal courts finding that the requirements are inconsistent with the core purpose of Medicaid, which is to provide healthcare coverage, rather than to promote work. The Biden administration withdrew approvals for work requirement waivers that had been granted by the Trump administration. The legal and policy debate about whether the federal government has authority to approve such waivers continues, and the question may ultimately be resolved by the Supreme Court. The research on Medicaid work requirements provides a relatively clear empirical finding: the requirements implemented in Arkansas reduced coverage without increasing employment, driven by administrative burden that disproportionately affected the individuals the program nominally targeted. Whether this evidence is persuasive to policymakers who see work requirements primarily as a values statement about the appropriate conditions for public benefit receipt, rather than primarily as an employment intervention, reflects the role of values alongside evidence in policy debates. The broader research literature on work requirements in public benefit programs, including SNAP and TANF, finds similar patterns: work requirements reduce benefit receipt, often through administrative attrition rather than employment gains, with minimal employment effects that are more likely explained by economic conditions than by the requirements themselves.
