In order to be eligible for Obamacare in Missouri, an individual must be a resident of the state and have a household income less than 400% of the federal poverty level. Additionally, they must not already be enrolled in Medicaid or Medicare. Individuals who are not lawfully present in the U.S., and those who are incarcerated, do not qualify for Obamacare coverage. If you meet these qualifications, you can apply through the Health Insurance Marketplace at healthcare.gov or contact your local health center to learn more about available plans and subsidies.
