Beginning October 1, 2026, certain lawfully present immigrants, including refugees and asylees without a green card, will no longer qualify for federally funded Medicaid or CHIP coverage, under a restriction Congress enacted in last year’s reconciliation law. The Congressional Budget Office estimates the change will leave about 100,000 more people uninsured by 2034, a figure KFF cites in its own review of the law’s rollout. The Centers for Medicare & Medicaid Services issued its own implementation guidance for the change in April 2026.

What Changes on October 1 Under the 2025 Reconciliation Law
The restriction traces to last year’s federal reconciliation law, and the Centers for Medicare & Medicaid Services issued its own implementation guidance for it in April 2026, confirming that new limits on federal Medicaid and CHIP matching funds take effect October 1, 2026. CMS ties the restriction to Section 71109 of the law, which narrows which noncitizen categories can draw federal matching dollars for their care. States, not the federal government, administer Medicaid day to day, so the practical effect lands in each state’s own eligibility system starting on that date.
The restriction is part of a broader pattern in the 2025 law, which narrowed Medicaid eligibility for several immigration categories at the same time, not refugees and asylees alone. CMS’s guidance addresses each category separately, but October 1, 2026 is the single effective date that applies across the board for every category covered by Section 71109.
Why Refugees and Asylees Lose an Exemption Other Immigrants Never Had
Refugees and asylees have historically been treated differently from other lawfully present immigrants under Medicaid. According to KFF’s explainer on Medicaid immigration verification, refugees and asylees were exempt from the five-year waiting period that applies to most other lawfully present immigrants, such as green-card holders, giving them immediate eligibility upon arrival. The October 1 change removes federal funding for that category specifically, along with certain other noncitizen groups identified in the guidance, which is why the effect falls hardest on refugees and asylees rather than on lawfully present immigrants broadly.
The CBO’s Estimate: About 100,000 More Uninsured by 2034
The Congressional Budget Office estimates the eligibility restriction will leave about 100,000 more people uninsured by 2034, a projection KFF cites in its own analysis of the law’s rollout. That figure is a ten-year, cumulative estimate, not a count of people losing coverage the moment the rule takes effect on October 1; CBO’s modeling accounts for people who would otherwise have gained refugee or asylee status and enrolled in Medicaid over the coming decade, not only the group currently enrolled today.
CBO’s estimate sits inside a broader set of coverage projections tied to the same reconciliation law, which the agency has updated as more provisions take effect. The 100,000 figure isolates this specific immigrant eligibility restriction from other coverage changes in the law, meaning it does not include people who might lose coverage for unrelated reasons, such as new work requirements affecting other Medicaid populations entirely.
What CMS Told States To Do Before the Deadline
CMS’s guidance goes beyond announcing the effective date. It directs states to update eligibility systems, applications, verification procedures and claims processing ahead of October 1, and offers technical assistance to help states identify which current enrollees fall into a newly excluded category. States received the guidance through a formal State Health Official letter, the standard mechanism CMS uses to instruct state Medicaid agencies on federal rule changes, giving them roughly six months between the April notice and the October deadline to adjust their systems.
Who Stays Covered Despite the Restriction
The guidance carves out specific exceptions. Emergency medical treatment remains federally funded regardless of a person’s immigration category, and CHIP coverage for lawfully residing children and pregnant women can continue under a state option some states have already adopted. Those exceptions mean the October 1 change narrows eligibility rather than eliminating Medicaid access altogether for every affected immigrant, though anyone outside an exempted category loses the federal funding that supported their coverage.
What a Household Typically Sees on the Notice
A Medicaid coverage-end notice tied to this change is expected to cite the specific immigration category no longer eligible for federal funding and a coverage-end date, rather than leaving a household to guess. States that already send redetermination notices for other reasons are applying similar formats to this category, based on CMS’s own description of how it expects states to communicate the change, though exact notice language can vary by state Medicaid agency, and a household that recently moved or changed contact information risks missing the notice altogether if its mailing address on file is out of date.
KFF’s full accounting of the rollout, drawn from CMS’s own guidance and the Congressional Budget Office’s coverage estimate, remains the clearest public record of how the restriction reaches refugees, asylees and the roughly 100,000 people CBO expects to lose coverage over the next several years.
Reading a Coverage-End Notice Before October 1
The eligibility change applies to specific noncitizen categories identified in federal guidance, not to every Medicaid recipient, and a notice arriving in a mailbox rarely explains which category a household falls into or what happens in the weeks right after coverage ends.
The SNAP & Medicaid Renewal Organizer includes 51 state packs, a renewal document checklist, and a renewal and reporting calendar for working through what a notice requires.
