The Indian Health Service (IHS) within the Department of Health and Human Services (HHS) is the lead federal agency charged with improving the health of American Indians and Alaska Natives. IHS provides health care for approximately 2.2 million eligible American Indians/Alaska Natives through a system of programs and facilities located on or near Indian reservations, and through contractors in certain urban areas. IHS provides services to members of 573 federally recognized tribes. It provides services either directly or through facilities and programs operated by Indian tribes or tribal organizations through self-determination contracts and self-governance compacts authorized in the Indian Self-Determination and Education Assistance Act (ISDEAA). The Snyder Act of 1921 provides general statutory authority for IHS. In addition, specific IHS programs are authorized by two acts: the Indian Sanitation Facilities Act of 1959 and the Indian Health Care Improvement Act (IHCIA). The Indian Sanitation Facilities Act authorizes the IHS to construct sanitation facilities for Indian communities and homes. IHCIA authorizes programs such as urban health, health professions recruitment, and substance abuse and mental health treatment, and permits IHS to receive reimbursements from Medicare, Medicaid, the State Children's Health Insurance Program (CHIP), the Department of Veterans Affairs (VA), and third-party insurers. Finally, the Public Health Service Act provides funds for the Special Diabetes Program for Indians grants administered by IHS. The IHS has three major sources of funding, described here in order of magnitude: (1) discretionary appropriations, (2) collections, and (3) mandatory appropriations. Unlike most agencies within HHS, which receive their appropriations through the Labor, Health and Human Services, and Education appropriations act, the IHS receives its discretionary appropriations through the Interior/Environment appropriations act. IHS's discretionary appropriations are divided into three accounts: (1) Indian Health Services, (2) Contract Support Costs, and (3) Indian Health Facilities. As a second source of funding, IHS collects and expends funds received as payment for health services provided. IHS has the authority to receive payments from other federal programs such as Medicaid, Medicare, CHIP, and the Department of Veterans Affairs. IHS also receives payments from state programs (such as workers compensation) and from private insurance. IHS, under its IHCIA collection authority, is able to retain these payments to increase services available to its beneficiaries. In addition to these collections, IHS collects rent from facilities it owns. The third and smallest source of IHS funding is a mandatory appropriation of $150 million annually to support the Special Diabetes Program for Indians. This mandatory funding was extended through FY2019 in the Bipartisan Budget Act of 2018 (BBA 2018, P.L. 115-123 ). The President's budget request proposes to shift the FY2019 appropriation to discretionary funding. Table 1 presents IHS's funding from FY2014 through the proposed President's FY2019 budget submission. The table generally shows increases in both appropriated funds and funds collected by IHS through FY2018. The table presents IHS's three budget accounts—Indian Health Services, Contract Support Costs, and Indian Health Facilities—and the funds collected and allocated to programs under these accounts. Collections and proposed and actual mandatory funding are subtracted from program-level funding to show the agency's discretionary budget authority. Although appropriations for IHS have increased over time, the FY2018 appropriation represents a larger increase than in prior years. In particular, the FY2018 appropriation included increases for a number of programs funded under the Indian Health Facilities account, which includes maintenance and improvement and construction of new facilities. In addition, the FY2018 appropriation increased funding for mental health and alcohol and substance abuse services, provided new funding for the Indian Health Care Improvement Fund, and included language to require IHS to conduct an analysis of IHS locations and services relative to the IHS user population. The FY2019 President's request represents a decrease from FY2018 levels for a number of IHS programs and activities. However, final FY2018 appropriations had not been enacted during the period in which the FY2019 President's request was being formulated. While the total request for IHS represents a decrease from FY2018-enacted levels, it represents an increase from FY2017-enacted levels and the FY2018 annualized continuing resolution levels that were in place at the time the FY2018 request levels were being determined. IHS facilities collect payments from third-party payors for services provided to IHS beneficiaries who are also enrolled in other programs. These collections are an important source of IHS's clinical services (see Table 1 ). Medicaid is the largest source of IHS's collections—accounting for approximately 68% of all third-party collections in FY2017, the most recent year of final data available—followed by Medicare (21% in FY2017) and private insurance (9% in FY2017). Beginning in FY2014, IHS began receiving payments from the VA for services provided to IHS beneficiaries who were also enrolled in the VA (these payments were 2% of all of IHS's third-party collections in FY2017). 

Summary: The Indian Health Service (IHS) within the Department of Health and Human Services (HHS) is the lead federal agency charged with improving the health of American Indians and Alaska Natives. IHS provides health care for approximately 2.2 million eligible American Indians/Alaska Natives through a system of programs and facilities located on or near Indian reservations, and through contractors in certain urban areas. IHS provides services to members of 573 federally recognized tribes. It provides services either directly or through facilities and programs operated by Indian tribes or tribal organizations through self-determination contracts and self-governance compacts authorized in the Indian Self-Determination and Education Assistance Act (ISDEAA). The IHS has three major sources of funding: (1) discretionary appropriations, (2) collections, and (3) mandatory appropriations. Unlike most agencies within HHS, which receive their appropriations through the Labor, Health and Human Services, and Education appropriations act, IHS receives its discretionary appropriations through the Interior/Environment appropriations act. IHS's discretionary appropriations are divided into three accounts: (1) Indian Health Services, (2) Contract Support Costs, and (3) Indian Health Facilities. IHS collects payments for the health services it provides. IHS, unlike other federal agencies, has the authority to receive payments from other federal programs such as Medicaid, Medicare, and the Department of Veterans Affairs for the health services it provides to IHS beneficiaries who are also enrolled in those programs. IHS also receives payments from state programs (such as workers' compensation) and from private insurance. In addition to these payments, IHS collects rent from facilities it owns. Since FY1998, IHS has received a mandatory appropriation each fiscal year to support the Special Diabetes Program for Indians. This funding source was most recently extended in the Bipartisan Budget Act of 2018 (P.L. 115-123), which provided mandatory appropriations for FY2018 and FY2019. The President's budget requests that these funds be moved to discretionary appropriations in FY2019. This fact sheet focuses on the funding that IHS has received between FY2014 and FY2019 (proposed).
