The "No Medicaid for Illegal Immigrants Act of 2025" proposes to amend title XIX of the Social Security Act, which governs the Medicaid program. Its primary objective is to prohibit states from making most medical assistance available to certain non-citizens. This includes individuals who are not lawfully admitted for permanent residence or otherwise permanently residing in the United States under color of law, effectively restricting Medicaid eligibility for undocumented immigrants. Specifically, the bill adds a new paragraph to section 1902(a) of the Social Security Act, ensuring that states cannot use federal Medicaid funds for these individuals. An important exception is made for emergency medical services , which would continue to be covered as currently permitted by existing federal law. This legislation aims to significantly alter Medicaid eligibility requirements for non-citizens.
