Key Points Question What is the association of Medicaid expansion under the Patient Protection and Affordable Care Act with suicide rates? Findings Although suicide rates increased from 2000 to 2018 across all states in this cross-sectional study, a statistically significant attenuation of −0.40 suicides per 100 000 people was found in Medicaid expansion states compared with nonexpansion states, translating to 1818 fewer suicides from 2015 to 2018. Meaning These findings suggest that Medicaid expansion, which increases mental health coverage, is associated with a decrease in suicide mortality.
