Why It Matters
A federal court order designed to limit how Immigration and Customs Enforcement accesses Medicaid data may have been violated by the Trump administration, according to a coalition of 22 states. The allegations have significant implications for Ohio and other states where millions of low-income residents rely on Medicaid for basic health coverage.
Health care advocates warn that unauthorized data sharing — even if later found to be inadvertent — could accelerate a chilling effect already underway, with eligible residents, including legal immigrants, avoiding Medicaid enrollment out of fear of immigration consequences.
What Happened
A coalition of 22 states and the District of Columbia filed a federal lawsuit seeking to block the Trump administration from sharing Medicaid enrollment data with ICE for use in deportation proceedings. In December 2025, a court issued a partial ruling that allowed ICE to access a limited category of data — including addresses, phone numbers, birth dates, and citizenship or immigration status.
Critically, the court also placed explicit restrictions on that access. ICE was barred from collecting information on lawful permanent residents or U.S. citizens, and the scope of permissible data sharing was narrowly defined.
The 22-state coalition has now returned to federal court alleging that the Trump administration appears to have gone beyond those restrictions, pulling Medicaid data in ways that violate the December court order. Ohio is among the states party to the lawsuit.
By the Numbers
22 states plus the District of Columbia are party to the lawsuit challenging ICE’s access to Medicaid data.
90 million Americans are enrolled in Medicaid nationally, making it one of the largest health insurance programs in the United States.
4 categories of data were explicitly permitted under the December court ruling: addresses, phone numbers, birth dates, and citizenship or immigration status.
0 — the number of categories under which ICE was authorized to access data on lawful permanent residents or U.S. citizens, per the court order.
In Ohio alone, approximately 3 million residents are enrolled in Medicaid, a significant portion of whom are immigrant families or households with mixed immigration status.
Zoom Out
The dispute is part of a broader pattern of legal conflicts between state governments and the Trump administration over immigration enforcement and access to federal health data. The Justice Department has already closed more than 23,000 criminal cases in the first six months of the Trump administration, redirecting prosecutorial resources toward immigration enforcement — signaling a sweeping realignment of federal law enforcement priorities.
Public health officials have raised alarms that immigration enforcement actions involving health data could undermine trust in public health systems more broadly. Ohio is already managing two measles outbreaks in 2026 amid scrutiny of federal vaccine guidance, and experts note that reduced Medicaid enrollment could further complicate disease surveillance and outbreak response efforts.
Similar data-sharing disputes have arisen in states including California, New York, and Washington, where state attorneys general have sought injunctions against federal agencies accessing sensitive health records without proper legal authorization.
What’s Next
The 22-state coalition is expected to press the federal court for a ruling on whether the Trump administration has in fact violated the December order, and potentially seek stronger injunctive relief or contempt proceedings if violations are confirmed.
Federal health officials have not yet publicly responded to the specific allegations outlined in the states’ court filing. Legal analysts expect the case to move quickly given the existing court order and the coalition’s claims of active, ongoing violations.
For Ohio residents, state health officials have urged eligible individuals to continue enrolling in Medicaid, emphasizing that the court order remains in effect and that enrollment data protections are currently being litigated and enforced. Advocates are also pushing state legislators to consider additional state-level protections for health data. Ohio House Democrats recently introduced a package of affordability bills targeting health care costs, though none directly address Medicaid data privacy in the context of immigration enforcement.
The case is being closely watched by health care attorneys, immigration advocates, and state lawmakers across the country as a test of the limits of federal executive authority over jointly administered state-federal programs.
