NEW YORK (AP) — Starting Monday, the nation’s health department can resume sharing the personal data of certain Medicaid enrollees with deportation officials, following a ruling from a federal judge that undermines privacy safeguards sought by several states.

U.S. District Judge Vince Chhabria's decision specifically permits the sharing of basic biographical information from 22 plaintiff states about immigrants who are residing illegally in the United States. This ruling comes after the Centers for Medicare and Medicaid Services expressed intentions to restart the data sharing as part of the Trump administration's stringent immigration policy.

Previously, Chhabria had blocked such sharing in August, citing concerns over the implications of using this data against individuals living without legal status. His latest ruling allows HHS to release “basic biographical, location and contact information” for undocumented immigrants but prohibits sharing sensitive medical data or information about U.S. citizens and lawful immigrants.

Advocates for immigrants worry that this data-sharing policy could deter individuals from seeking emergency medical assistance due to fear of deportation. Initial disclosures of personal data to ICE reignited privacy concerns and prompted lawsuits from states advocating for immigrant protections.

The ruling highlights ongoing tensions between immigration enforcement and healthcare access, reflecting the broader implications of the Trump administration's immigration crackdown, which has seen collaborative efforts across federal authorities to detain individuals living unlawfully in the U.S.

It remains to be seen how health officials will navigate these new guidelines and what impact they will have on the immigrant community’s willingness to access medical care.
