Abstract Context: States have sought to experiment with the income eligibility threshold between Medicaid coverage and access to subsidized Marketplace plans in an effort to increase coverage for low-income adults while meeting other state priorities, particularly a balanced budget. In 2014, Wisconsin opted against adoption of an ACA Medicaid expansion, instead setting the Medicaid eligibility threshold at 100% of the poverty level—a state-funded partial expansion. Childless adults gained new eligibility, while parents and caregivers with incomes between 101–200% of poverty lost existing eligibility. Methods: We use Wisconsin’s all-payer claims database to assess health insurance gains, losses, and transitions among low-income adults affected by this partial expansion. Findings: We find that less than one third of adults who lost Medicaid eligibility definitely took up commercial coverage, and many returned to Medicaid. Among those newly Medicaid eligible, there was little evidence of crowd-out. Both groups experienced limited continuity of coverage. Overall, new Medicaid enrollment of childless adults was offset by coverage losses among parents and caregivers, rendering Wisconsin’s overall coverage gains similar to non-expansion states. Conclusions: Wisconsin’s experience demonstrates the difficulty in relying on the Marketplace to cover the near poor and suggests that full Medicaid expansion more effectively increases coverage.

Objectives: To investigate the association of state-level Medicaid expansion and non-elderly mortality rates from 1999 to 2018 in Northeastern urban settings.Methods: This quasi-experimental study utilized a synthetic control method to assess the association of Medicaid expansion on non-elderly urban mortality rates [1999–2018]. Counties encompassing the largest cities in the Northeastern Megalopolis (Washington D.C., Baltimore, Philadelphia, New York City, and Boston) were selected as treatment units (n = 5 cities, 3,543,302 individuals in 2018). Cities in states without Medicaid expansion were utilized as control units (n = 17 cities, 12,713,768 individuals in 2018).Results: Across all cities, there was a significant reduction in the neoplasm (Population-Adjusted Average Treatment Effect = −1.37 [95% CI −2.73, −0.42]) and all-cause (Population-Adjusted Average Treatment Effect = −2.57 [95%CI −8.46, −0.58]) mortality rate. Washington D.C. encountered the largest reductions in mortality (Average Treatment Effect on All-Cause Medical Mortality = −5.40 monthly deaths per 100,000 individuals [95% CI −12.50, −3.34], −18.84% [95% CI −43.64%, −11.67%] reduction, p = < 0.001; Average Treatment Effect on Neoplasm Mortality = −1.95 monthly deaths per 100,000 individuals [95% CI −3.04, −0.98], −21.88% [95% CI −34.10%, −10.99%] reduction, p = 0.002). Reductions in all-cause medical mortality and neoplasm mortality rates were similarly observed in other cities.Conclusion: Significant reductions in urban mortality rates were associated with Medicaid expansion. Our study suggests that Medicaid expansion saved lives in the observed urban settings.
