CMS Orders States to Verify Immigrant Medicaid Eligibility by October 1
States must redetermine immigration status for Medicaid beneficiaries by October 1, 2026, or face loss of federal funding, CMS warned in a new implementation guide on August 4. The deadline signals major changes in which immigrants can qualify for federally funded health coverage.
On August 4, 2026, the Centers for Medicare & Medicaid Services (CMS) released an implementation guide requiring all U.S. states to redetermine the immigration status of current Medicaid beneficiaries before October 1, 2026. States that fail to complete these verifications risk federal reimbursement sanctions and must stop submitting federal claims for beneficiaries whose eligibility has not been verified by the deadline.
This directive enforces new federal restrictions on immigrant Medicaid eligibility that took effect in 2026. Beginning October 1, 2026, only citizens, nationals, and certain narrow immigrant categories including legal permanent residents, Cuban/Haitian entrants, and Compact of Free Association migrants will remain eligible for nonemergency Medicaid with federal funding, while other immigration statuses—including refugees, asylees, and trafficking survivors—no longer will qualify.
Who Is Affected
Immigrant children and pregnant people lawfully residing in the U.S. for less than five years must have their immigration status re-verified at renewal, and states must act immediately if they receive information about changes in enrollees' immigration status that might affect ongoing eligibility. The verification wave will likely result in coverage losses for millions of immigrants, particularly those with protected status like T and U visa holders.
What Happens After October 1
Affected immigrants will remain eligible for emergency Medicaid and coverage under CHIP provisions for noncitizen children and pregnant women, though states may continue to provide additional health coverage to these groups using state-only funding.
If you are a lawfully present immigrant, refugee, asylee, or trafficking survivor: Do not assume your Medicaid coverage will continue past October 1, 2026. Contact your state Medicaid agency or a certified enrollment counselor immediately to verify your eligibility before the deadline. Some states may offer state-funded alternatives for those losing federal coverage. Undocumented immigrants will retain emergency Medicaid access but should verify current status with their state health department.
