The Trump administration has established a new data-sharing agreement that allows the Centers for Medicare and Medicaid Services (CMS) to share Medicaid data with the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE) for immigration enforcement purposes.
This policy represents a reversal of previous government assurances. For decades, the government maintained that information collected to determine eligibility for health coverage programs would not be used for immigration enforcement. These commitments were previously explicitly stated on government websites.
Impact on Patient Access and Public Health
The shift in policy has created significant fear among immigrant communities, including those with legal immigration status. Patients have expressed concern that enrolling in or maintaining health insurance could put their families at risk of being detained or deported.

Public health experts warn that this environment of fear may deter immigrants from seeking essential medical care. Leonardo Cuello, a research professor at Georgetown University’s Center for Children and Families, noted that if patients are informed that their information is shared with ICE, many may stop seeking emergency medical treatment.
A specific concern involves Emergency Medicaid, a program that reimburses hospitals for the cost of emergency treatment for immigrants who are ineligible for standard Medicaid coverage. According to Cuello, half of these cases involve the delivery of U.S. Citizen babies, raising concerns that mothers may avoid hospitals when they go into labor.
Legal and Operational Challenges
The implementation of this data-sharing agreement faces legal hurdles. Currently, 22 plaintiff states are challenging the policy in court. Under pending litigation, CMS is prohibited from sharing certain information from these plaintiff states, specifically regarding citizens or individuals who are lawfully present.
However, KFF reports that data limitations may make it difficult for CMS to comply with this court order. If the data available to CMS is similar to the data accessible to researchers, it may be impossible to isolate only those individuals who are not lawfully present within the datasets shared with ICE.
Historical Context of Health Data Privacy
The current policy contradicts a 2013 ICE policy memo that guaranteed the agency would not use information from health coverage applications for enforcement activities. This long-standing approach was intended to ensure that eligible immigrants felt comfortable accessing care without jeopardizing their immigration status.
The transition to the current system began after President Donald Trump returned to the White House and initiated a broader effort to funnel data from various government agencies, including the IRS, to the Department of Homeland Security.
My daughter’s life depends on Medicaid
A parent interviewed by NPR
The parent, identified only as P., stated that while her family has legal immigration status, she fears that the insurance keeping her medically fragile daughter alive could lead to the family being located by immigration authorities.
Current Situation for Providers
Hospitals and state agencies are now facing a dilemma regarding patient disclosure. Providers must weigh the risk of alerting immigrant patients that their personal information, including home addresses, could be used for removal efforts against the risk of patients remaining unaware that their medical coverage may expose them to ICE.
