Above: We first illustrate the sudden cut to Medicaid eligibility among working-age adults in Tennessee in the middle of 2005. We then plot the fraction of (i) the “TennCare disenrollees” who remained uninsured many years after losing eligibility and (ii) adults enrolled in Medicaid in 2005 in states where similar waivers for eligibility remained intact.
Working paper coming soon
Abstract
Once considered a model for national health insurance reform, Tennessee’s Medicaid program, TennCare, later experienced one of the largest public health insurance cuts in United States history. The severity of Medicaid eligibility cuts to a vulnerable population may have led to both short and long-term impacts to their health insurance, labor market, and health outcomes. Although the “TennCare disenrollment” has been studied in the past, the set of disenrollees has not been specified and tracked over a long period of time, as we do in this paper by linking administrative enrollment records from CMS to large household surveys from the Census Bureau. Our unique dataset allows us to pinpoint individuals who lost TennCare eligibility and trace their long-term outcomes. We first show that nearly half of the 160,000 TennCare disenrollees were still uninsured several years after the disenrollment. Although many disenrollees gained insurance through an employer, we do not find increases in labor force participation or employment among the disenrolled. The results may conflict with theories of employment or job lock, wherein Americans seek work in order to obtain health insurance. Finally, we consider the health outcomes of the disenrollees. We do not find that public health insurance improves self-reported measures of disability. Collectively, our results are largely consistent with the experimental literature but contrast with the quasi-experimental literature on the impacts of health insurance. Our findings come at a time when Medicaid faces budgetary challenges, and we conclude our paper by discussing several budgetary lessons from the TennCare experience that may inform current policy discussions. We also emphasize that our template can be applied to study other changes in access to Medicaid, such as the unwinding of pandemic provisions or large future Medicaid cuts, should they occur.
