The Navajo Area IHS Office, located in Window Rock, Arizona, administers numerous clinics, health centers, and hospitals, providing health care to 201,583 members of the Navajo Nation. The Navajo Nation is the largest Indian tribe in the United States and has the largest reservation, which encompasses more than 25,516 square miles in northern Arizona, western New Mexico, and southern Utah, with three satellite communities in central New Mexico. School clinics and Navajo tribal health programs also serve the community. The six hospitals range in size from 39 beds in Crownpoint, New Mexico, to 112 beds at the Gallup Indian Medical Center in Gallup, New Mexico.
Health centers operate full-time clinics, some of which provide emergency services.
Some smaller communities have health stations that operate only part-time. The NDOH, created in 1977, has the mission of ensuring that quality and culturally acceptable health care is available and accessible to the Navajo people through coordination, regulation, and where necessary, direct service delivery.
