The Trump administration has given Immigration and Customs Enforcement (ICE) access to Medicaid data for approximately 79 million policyholders.[2][3][4][9] Data includes name, address, telephone number, date of birth, Medicaid ID number, social security, ethnicity, and race.[1][2][3] Access is through the CMS Integrated Data Repository and T-MSIS to identify and locate aliens in the US, including bank data such as routing number and account number.[1][2] In December 2025, the court modified the decision, allowing only the sharing of data about persons without legal residence in the US, limited to citizenship, immigration status, address, telephone, date of birth and Medicaid ID, without health information.[1][6][7] Data sharing began on January 6, 2026 and continues through September 9 during business hours, with no data downloads available.[2][3][6] Hospitals and states face the dilemma of whether to notify immigrants of this access to their personal data.
