This analysis evaluates the impact of the 2014 Medicaid expansion on health insurance coverage and cost-related access barriers using difference-in-differences methodology applied to BRFSS survey data (2011-2017, N=294,018). Results indicate that Medicaid expansion significantly reduced the odds of being uninsured by approximately 13% (OR=0.87, 95% CI: 0.80-0.94, p=0.001) in expansion states compared to non-expansion states. However, no significant effect was detected on cost-related barriers to seeing a doctor (OR=1.07, 95% CI: 0.99-1.15, p=0.091). Findings support Medicaid expansion as an effective policy tool for increasing insurance coverage.
