The Indian Health Service (IHS) is an agency of the United States Department of Health and Human Services, which provides healthcare services to American Indian and Alaska Native communities across the United States. The IHS is responsible for providing medical and public health services to approximately 2.6 million Native Americans, including tribal members and descendants, living in 574 federally recognized tribal communities. The IHS operates a network of 25 hospitals, 59 health centers, and 32 health stations. These facilities provide a range of services, including preventive care, primary care, behavioral health, dental care, and specialty care. The IHS also provides health education and disease prevention programs, as well as community health services and environmental health services. The IHS works closely with tribal governments and other healthcare providers to ensure that Native Americans receive quality healthcare services that are culturally and linguistically appropriate. The agency is committed to improving the health and well-being of Native American communities and works to address the unique health challenges they face. These challenges include chronic disease, mental health issues, substance abuse, and inadequate access to healthcare services. The IHS is funded through a combination of federal appropriations and third-party reimbursements. The agency is also involved in research and training programs aimed at improving the delivery of healthcare services to Native American communities. The agency’s mission is to raise the physical, mental, social, and spiritual health of American Indians and Alaska Natives to the highest level.
