The Division of Immigration Heatlh Servies (DIHS) provides or arranges for health care services for undocumented migrants detained by the U.S. Immigration and Customs Enforcement (ICE). DIHS's relationship with the ICE dates back to 1891 when the Immigration Act authorized the Public Health Service to examine and quarantine aliens at Ellis Island.


The DIHS health care system is a complex system that includes several distinct activities and services required by DHS to support the enforcement of immigration law and maintain national security. The system includes:

  • Ambulatory care clinics, in-patient units, mental health units, and medical staging facilities co-located with Immigration Service Processing Centers and contract detention facilities;
  • A managed care/utilization management system which arranges health services to support undocumented migrants detained in over 500 federal, state and local jails;
  • A managed care/utilization management system which provides health care support for unaccompanied undocumented juveniles under the care of Office of Refugee Resettlement, Department of Health and Human Services,
  • Medical claims processing for the US Border Patrol,
  • Consultation and support upon request for US Customs Inspections,
  • Year round medical personnel to augment US Coast Guard missions at sea in the Caribbean on migrant interdiction operations,
  • Certified Flight Nurses who provide in-flight medical support for removal of sick or dangerous deportees.
