On July 15, 2025, the Trump administration finalized an arrangement granting Immigration and Customs Enforcement (ICE) access to personal data from approximately 79 million Medicaid recipients. Under an agreement between the Centers for Medicare and Medicaid Services (CMS) and the Department of Homeland Security (DHS), ICE will be able to access sensitive demographic and identifying information—such as names, addresses, birth dates, ethnicities, and Social Security numbers—through the Transformed Medicaid Statistical Information System (T-MSIS) AP News.

Although the deal extends for only two months (July 15–September 15, 2025), its scope is far beyond typical Medicaid fraud detection tools. While CMS and DHS framed it as a cost-saving measure to prevent unauthorized Medicaid claims, critics assert the move targets undocumented immigrants and breaches long-standing health-data privacy norms AP News.

The agreement clearly states that ICE may use the data to locate individuals for deportation purposes, though it does not permit bulk data downloads—ICE can query data on demand during business hours only. Nonetheless, legal and privacy experts warn it could discourage vulnerable groups, such as undocumented immigrants or those fearing enforcement, from seeking essential or emergency medical care AP News.

State officials and lawmakers have expressed concern. California Senator Alex Padilla and Senator Adam Schiff sent a letter to the administration urging immediate cessation and the deletion of any collected data. California’s Attorney General Rob Bonta and nineteen other states have filed a lawsuit, arguing the data-sharing violates federal privacy protections including the Health Insurance Portability and Accountability Act (HIPAA) AP News.

Internally, CMS career staff reportedly opposed the transfer, collecting emails that reveal they had less than one hour (54 minutes) to comply after being ordered by Health Secretary Robert F. Kennedy Jr. — raising procedural and legal concerns CalMatters.

Although emergency Medicaid benefits are legally accessible to undocumented immigrants, federal law forbids standard Medicaid enrollment for noncitizens—underscoring that CMS claimed cost recovery as the motive. Nonetheless, analysts argue the timing and implications align with broader Trump-era immigration enforcement directives (e.g., Executive Order 14159 restricting benefits and expanding enforcement) .

Public health advocates warn of a “chilling effect”: eligible people avoiding Medicaid out of fear of ICE detection, which could lead to worse health outcomes and higher long-term federal spending . Medicaid chairs from multiple states echoed fear that trust in public programs is eroding, and that lives may be endangered due to reluctance to seek care AP News.
