Federal Court Blocks Sharing of Medicaid Data with Homeland Security
Update: Aug 5-22, 2025
A federal court in northern California has issued a preliminary injunction preventing the U.S. Department of Health and Human Services (DHHS) from providing Medicaid recipients’ personal healthcare information to the Department of Homeland Security (DHS). The ruling comes after a coalition of attorneys general in several states, including Michigan’s Dana Nessel, challenged DHHS’ decision to share this private medical information for immigration enforcement purposes.
The court determined that DHHS and DHS had not done their due diligence through thorough consideration of how to limit the scope of medical information shared before suddenly changing their well-established privacy policy. The court order prevents DHHS from sharing Medicaid data with DHS until after the lawsuit is completed or a comprehensive rulemaking process weighing the legal ramifications has been conducted.
