Navajo Area Indian Health Service
The Navajo Area Indian Health Service (NAIHS) is one of 12 regional administrative units of the Indian Health Service (IHS), in the US Department of Health and Human Services. The NAIHS delivers health services to a user population of over 244,000 American Indians in five Federal service units on and near the Navajo Nation.

NAIHS primarily delivers health services to members of the Navajo Nation and the San Juan Southern Paiute Tribe, and also provides services to other Native Americans, including Zunis, Hopis, and other American Indian beneficiaries. The five (5) Federal Service Units (SUs) include Chinle, Crownpoint, Gallup, Kayenta, and Shiprock.
