New rules governing data sharing within Medicaid are raising concerns among immigrant communities across the United States, with some families now hesitant to enroll in the program despite their eligibility. The changes, stemming from a December court ruling, reverse decades of assurances that personal information shared with Medicaid would remain private and protected from immigration enforcement. This shift in policy is creating a climate of fear, potentially impacting access to vital healthcare services for millions.
For families like P’s, who asked that only her first initial be used due to fears of detention, Medicaid is a lifeline. P and her husband, both working and with private health insurance, rely on Medicaid to cover the extensive medical needs of their two children, one of whom has Rett syndrome, a rare neurological disorder. The cost of in-home support, physical therapy, occupational therapy, speech therapy, and frequent doctor’s visits would be insurmountable without the program. As reported by NPR, P’s family moved to the U.S. From Brazil in 2016 specifically to access specialized medical care for her daughter. Now, the promise of that access is clouded by anxiety.
A Reversal of Long-Standing Policy
The core of the issue lies in the Trump administration’s push to share data with Immigration and Customs Enforcement (ICE). A federal judge ruled in December 2025 that the administration could resume sharing location data about undocumented immigrants receiving Medicaid benefits with ICE, as detailed in a report from Politico. This decision overturned a long-held understanding that Medicaid information would not be used for immigration enforcement purposes. Cindy Mann, who oversaw Medicaid during the Obama administration and is now a partner at the legal and consulting firm Manatt Health, described the change as a “180-degree reversal of long-standing policy.”
Historically, Mann explained, Medicaid data was only shared with the federal government for oversight – verifying eligibility and ensuring program integrity. The Department of Health and Human Services (HHS) maintains that this remains the case, but the sharing of names and addresses with immigration authorities has understandably fueled distrust within immigrant communities. The commitment to privacy, once prominently displayed on government websites, has now been removed, further exacerbating concerns.
Impact on Enrollment and Access to Care
The practical consequences of this policy shift are already being felt. Pattie Lopez, who manages the health insurance department at Venice Family Clinic in Los Angeles, has received calls from patients questioning the safety of remaining enrolled in Medicaid. As NPR reported, one woman, overwhelmed by fear, initially dropped her Medicaid coverage, only to reinstate it when she realized the necessity of continued access to medication. Eighty percent of the clinic’s patients rely on Medicaid, and a widespread exodus from the program could create significant financial strain, leading to hiring freezes and cost-cutting measures.
The situation varies by state. In December, a judge issued a temporary limitation on data-sharing in 22 states that had sued, restricting the practice to individuals unlawfully present in the country. These states include Arizona, Michigan, and New Jersey. However, in the remaining 28 states, including Texas, Kentucky, and Utah, there are currently no such restrictions, according to NPR. This creates a patchwork of policies, adding to the confusion and anxiety among immigrant families.
Existing Information and Potential Risks
Andrew Cohen, an attorney with Health Law Advocates in Massachusetts, notes that the federal government may already possess information on individuals enrolled in Medicaid or other public assistance programs. Remaining enrolled may not necessarily increase risk in all cases. However, he cautions that the level of risk is not uniform and depends on individual circumstances. It remains unclear whether the data already shared with immigration authorities has been used to identify individuals for enforcement actions; DHS did not respond to NPR’s inquiries on this matter.
The potential for misuse of this data is a significant concern. Even for those with legal immigration status, like P and her family, the fear of being swept up in immigration enforcement actions is palpable. “It bring us an amount of anxiety every day,” P shared with NPR. “Your friends are around you that are just being arrested, and you don’t know if that can happen with you, too.”
This situation underscores the broader impact of immigration policies on public health. When individuals fear accessing essential healthcare services, it not only jeopardizes their own well-being but also poses a risk to the broader community. The long-term consequences of this policy shift remain to be seen, but the immediate impact is a growing sense of fear and uncertainty within immigrant communities.
The legal challenges to the data-sharing rule are ongoing, and further developments are expected in the coming months. Individuals with questions about their eligibility or concerns about data privacy are encouraged to consult with legal aid organizations or healthcare navigators. For those seeking assistance, resources are available through organizations like Health Law Advocates and Venice Family Clinic.
