The Indian Health Service Albuquerque Area is responsible for the provision of health services to 27 distinctly different tribal groups. The Area serves 20 Pueblos, two Apache bands, three bands of the Navajo Nation and two Ute tribes across four Southwest states to include New Mexico, Colorado, Texas and Utah. Additionally, numerous tribal members from throughout the United States who live, work, or go to school in the urban centers of the Albuquerque Area are provided services in health facilities operated by the Indian Health Service. The administrative headquarters of the Area are located in Albuquerque, New Mexico. Across the Area care is via five hospitals, eleven health centers, and twelve field clinics, which deliver care at the community level. These facilities are administratively divided into eight service delivery areas called "Service Units."
