The Affordable Care Act Medicaid expansion: a difference-in-differences study of spillover participation in SNAP.
Medicaid expansion through the Affordable Care Act increased access to insurance coverage to adults under 138% of the federal poverty level and connected individuals to SNAP (the Supplemental Nutrition Assistance Food Program – formerly the Food Stamp Program). The purpose of this study was to estimate the effect of Medicaid expansion on SNAP participation among 414,000 individuals across the U.S. The study found that there was a 2.9% increase in SNAP participation produced by Medicaid expansion among individuals living under 138% of the federal poverty level. In subgroup analyses the researchers discovered a 5% increase in households without children below 75% of the federal poverty level, and an increase in SNAP households with zero dollars in income. The study concluded that the impact of the Medicaid expansion on access to SNAP participation was the greatest in very-low-income individuals, and that the impact of Medicaid expansion reaches beyond healthcare by increasing access to other supports like food which is a social determinant of health.

Medicaid expansion in social context: examining relationships between Medicaid enrollment and county-level food insecurity.
This study examined the relationship between states’ expansion of Medicaid and county-level food insecurity. They examined county Medicaid enrollment in early expansion states and found that increased Medicaid enrollment was associated with lower food insecurity during two expansion periods (2009-2012; 2012-2014). In California the most pronounced associations were evident in counties with the largest Medicaid expansions.

Massachusetts inpatient Medicaid cost response to increased supplemental nutrition assistance program benefits.
This study investigated the impact of an increase in Supplemental Nutrition Assistance Program (SNAP) benefits on Medicaid costs and use in Massachusetts. It found that compared with the overall Medicaid population, cost growth for people with the selected chronic illnesses was significantly greater before the SNAP increase, as was the decline in growth afterward. Reduced hospital admissions after the SNAP increase drove the cost declines.
