The mission of HHS is to "enhance the health and well-being of Americans by providing for effective health and human services and by fostering sound, sustained advances in the sciences underlying medicine, public health, and social services." HHS is currently organized into 11 main agencies, called "operating divisions" (listed below), which are responsible for administering a wide variety of health and human services programs, and conducting related research. In addition, HHS has a number of "staff divisions" within the Office of the Secretary (OS). These staff divisions fulfill a broad array of management, research, oversight, and emergency preparedness functions in support of the entire department. HHS Operating Divisions Eight of the HHS operating divisions are part of the U.S. Public Health Service (PHS). PHS agencies have diverse missions in support of public health, including the provision of health care services and supports (e.g., IHS, HRSA, SAMHSA); the advancement of health care quality and medical research (e.g., AHRQ, NIH); the prevention and control of disease, injury, and environmental health hazards (e.g., CDC, ATSDR); and the regulation of food and drugs (e.g., FDA). The three remaining HHS operating divisionsâACF, ACL, and CMSâare not PHS agencies. ACF and ACL largely administer human services programs focused on the well-being of vulnerable children, families, older Americans, and individuals with disabilities. CMSâwhich accounts for the largest share of the HHS budget by farâis responsible for administering Medicare, Medicaid, and the State Children's Health Insurance Program (CHIP), in addition to some aspects of the private health insuranceÂ market. (For a summary of each operating division's mission and links to agency resources related to the FY2020 budget request, see the Appendix .) The initial President's budget request for FY2020 was submitted to Congress on March 11, 2019, about five weeks after the statutory deadline. (Additional components of the FY2020 request were released in subsequent weeks.) The delay in the budget submission was attributable, in part, to protracted negotiations over seven of the FY2019 annual appropriations acts, which resulted in a five-week partial government shutdown. (Five of the 12 annual appropriations acts had already received full-year appropriations for FY2019 when the shutdown commenced.) At HHS, the FY2019 shutdown primarily affected FDA, IHS, and ATSDR. The remaining HHS operating and staff divisions generally had already received full-year FY2019 funding prior to the start of the fiscal year (Division B of P.L. 115-245 ). Full-year appropriations for FDA, IHS, and ATSDR were ultimately enacted on February 15, 2019, almost five months after the start of the fiscal year ( P.L. 116-6 ). In light of this delay, the source of the FY2019 numbers contained in the FY2020 President's budget materials varies by HHS agency. In the case of FDA, IHS, and ATSDR, amounts shown for FY2019 were estimated based on annualized funding levels under the FY2019 continuing resolution (Division C of P.L. 115-245 , as amended), not final full-year enacted levels. By contrast, amounts shown for the remaining HHS agencies generally reflect enacted full-year appropriations provided in Division B of P.L. 115-245 . Under the President's budget request, HHS would spend an estimated $1.286 trillion in outlays in FY2020 (see Table 1 ). This is $56 billion (+5%) more than estimated HHS spending in FY2019 and about $166 billion (+15%) more than actual HHS spending in FY2018. Historical estimates by the Office of Management and Budget (OMB) indicate that HHS has accounted for at least 20% of all federal outlays in each year since FY1995. Most recently, OMB estimated that HHS accounted for 27% of all federal outlays in FY2018. Figure 1 displays proposed FY2020 HHS outlays by major program or spending category in the President's request. As this figure shows, mandatory spending typically accounts for the vast majority of the HHS budget. In fact, two programsâMedicare and Medicaidâare expected to account for 86% of all estimated HHS spending in FY2020. Medicare and Medicaid are "entitlement" programs, meaning the federal government is required to make mandatory payments to individuals, states, or other entities based on criteria established in authorizing law. This figure also shows that discretionary spending accounts for about 8% of estimated FY2020 HHS outlays in the President's request. Although discretionary spending represents a relatively small share of total HHS spending, the department nevertheless receives more discretionary money than most federal departments. According to OMB data, HHS accounted for 7% of all discretionary budget authority across the government in FY2018, the same as the Department of Homeland Security. The Department of Defense was the only federal agency to account for a larger share of all discretionary budget authority in that year (47%). Readers should be aware that the HHS budget includes a broader set of budgetary resources than the amounts provided to HHS through the annual appropriations process. As a result, certain amounts shown in FY2020 HHS budget materials (including amounts for prior years) will not match amounts provided to HHS by annual appropriations acts and displayed in accompanying congressional documents. There are several reasons for this: M andatory spending makes up a large portion of the HHS budget, and much of that spending is provided directly by authorizing laws, not through appropriations acts. All discretionary spending is controlled and provided through the annual appropriations process. By contrast, all mandatory spending is controlled by the program's authorizing statute. In most cases, that authorizing statute also provides the funding for the program. However, the budget authority for some mandatory programs (including Medicaid), while controlled by criteria in the authorizing statute, must still be provided through the annual appropriations process; such programs are commonly referred to as "appropriated entitlements" or "appropriated mandatories." The HHS budget request takes into account the department as a whole, while the appropriations process divides HHS funding across three different appropriations bills. Most of the discretionary funding for the department is provided through the Departments of Labor, Health and Human Services, and Education, and Related Agencies (LHHS) Appropriations Act. However, funding for certain HHS agencies and activities is appropriated in two other billsâthe Departments of the Interior, Environment, and Related Agencies Appropriations Act (INT) and the Agriculture, Rural Development, Food and Drug Administration, and Related Agencies Appropriations Act (AG). Table 2 lists HHS agencies by appropriations bill. The Administration may choose to follow different conventions than those of congressional scorekeepers for its estimates of HHS programs. For example, certain transfers of funding between HHS agencies (or from HHS to other federal agencies) that occurred in prior fiscal years, or are expected to occur in the current fiscal year, may be accounted for in the Administration's estimates but not necessarily in the congressional documents. HHS budget materials include two different estimates for mandatory spending programs in FY2019 when appropriate: proposed law and current law . Proposed law estimates take into account changes in mandatory spending proposed in the FY2020 HHS budget request. Such proposals would need to be enacted into law to affect the budgetary resources ultimately available to the mandatory spending program. HHS materials may also show a current law or current services estimate for mandatory spending programs. These estimates assume that no changes will be made to existing policies, and instead estimate mandatory spending for programs based on criteria established in current authorizing law. The HHS budget estimates in this report reflect the proposed law estimates for mandatory spending programs, but readers should be aware that other HHS, OMB, or congressional estimates might reflect current law instead. In some cases, agencies within HHS have the authority to expend user fees and other types of collections that effectively supplement their appropriations. In addition, agencies may receive transfers of budgetary resources from other sources, such as from the Public Health Service Evaluation Set-Aside (also referred to as the PHS Tap) or one of the mandatory funds established by the Patient Protection and Affordable Care Act (ACA; P.L. 111-148 , as amended). Budgetary totals that account for these sorts of resources in the Administration estimates are referred to as being at the "program level." HHS agencies that have historically had notable differences between the amounts in the appropriations bills and their program level include FDA (due to user fees) and AHRQ (due to transfers). The program level for each agency is listed in the table entitled "Composition of the HHS Budget Discretionary Programs" in the HHS FY2020 Budget in Brief. Figure 2 provides a breakdown of the FY2020 HHS budget request by operating division. When taking into account both mandatory and discretionary budget authority (i.e., total budget authority shown in Figure 2 ), CMS accounts for the largest share of the request (nearly $1.17 trillion). The majority of the CMS budget request would go toward mandatory spending programs, such as Medicare and Medicaid. When looking exclusively at discretionary budget authority, funding for CMS is comparatively smaller, accounting for just $3.6 billion of the HHS discretionary request. The largest share of the discretionary request would go to the PHS agencies (roughly $59.4 billion in combined funding for FDA, HRSA, IHS, CDC, ATSDR, NIH, and SAMHSA; no funds would go to AHRQ under the request ). NIH would receive the largest amount ($33.5 billion) of discretionary budget authority of any HHS operating division, and ACF would receive the second-largest amount ($18.3 billion). Table 3 puts the FY2020 request for each HHS operating division and the Office of the Secretary into context, displaying it along with estimates of funding provided over the three prior fiscal years (FY2017-FY2019). These totals are inclusive of both mandatory and discretionary funding. The amounts in this table are shown in terms of budget authority (BA) and outlays. BA is the authority provided by federal law to enter into contracts or other financial obligations that will result in immediate or future expenditures involving federal government funds. Outlays occur when funds are actually expended from the Treasury; they could be the result of either new budget authority enacted in the current fiscal year or unexpended budget authority that was enacted in previous fiscal years. As a consequence, the BA and outlays in this table represent two different ways of accounting for the funding that is provided to each HHS agency through the federal budget process. For example, Table 3 shows $0 in FY2020 BA for AHRQ because the President's budget proposes to eliminate this agency; however, the table shows an estimated $299 million in FY2020 AHRQ outlays, reflecting the expected expenditure of funds previously provided to the agency. This appendix provides for each operating division a brief summary of its mission, the applicable appropriations bill, the FY2020 budget request level, and links to additional resources related to that request. Food and Drug Administration (FDA) The FDA mission is focused on regulating the safety, efficacy, and security of human foods, dietary supplements, cosmetics, and animal foods; and the safety and effectiveness of human drugs, biological products (e.g., vaccines), medical devices, radiation-emitting products, and animal drugs. It also regulates the manufacture, marketing, and sale of tobacco products.

Centers for Disease Control and Prevention (CDC) and Agency for Toxic Substances and Disease Registry (ATSDR) The CDC mission is focused on "disease prevention and control, environmental health, and health promotion and health education." CDC is organized into a number of centers, institutes, and offices, some focused on specific public health challenges (e.g., injury prevention) and others focused on general public health capabilities (e.g., surveillance and laboratory services). In addition, the Agency for Toxic Substances and Disease Registry (ATSDR) is headed by the CDC director. For that reason, the ATSDR budget is often shown within CDC. Following the conventions of the FY2020 HHS BIB, ATSDR's budget request is included in the CDC totals shown in this report. ATSDR's work is focused on preventing or mitigating adverse effects resulting from exposure to hazardous substances in the environment.

Summary: Historically, the U.S. Department of Health and Human Services (HHS) has been one of the larger federal departments in terms of budgetary resources. Estimates by the Office of Management and Budget (OMB) indicate that HHS has accounted for at least 20% of all federal outlays in each year since FY1995. Most recently, HHS is estimated to have accounted for 27% of all federal outlays in FY2018. Final FY2019 appropriations had not been enacted for a few HHS operating divisions and accounts prior to the development of the FY2020 President's budget request. As a result, the FY2019 estimates contained in FY2020 President's budget materials (and this report) are based on annualized amounts provided in the FY2019 continuing resolution for this subset of HHS accounts. The remainder of the HHS estimates for FY2019 are based on enacted full-year appropriations contained in Division B of P.L. 115-245 , along with current services estimates for mandatory spending. Under the FY2020 President's budget request, HHS would spend an estimated $1.286 trillion in outlays in FY2020. This is $56 billion (+5%) more than estimated HHS spending in FY2019 and $166 billion (+15%) more than actual HHS spending in FY2018. Mandatory spending typically comprises the majority of the HHS budget. Two programsâMedicare and Medicaidâare expected to account for 86% of all estimated HHS spending in FY2020, according to the President's budget request. Medicare and Medicaid are "entitlement" programs, meaning the federal government is required to make mandatory payments to individuals, states, or other entities based on criteria established in authorizing law. Discretionary spending accounts for about 8% of HHS outlays in the FY2020 President's budget request. Although discretionary spending represents a relatively small share of total HHS spending, the department nevertheless receives more discretionary money than most federal departments. According to OMB data, HHS accounted for 7% of all discretionary budget authority across the government in FY2018. This report provides information about the FY2020 HHS budget request. It begins with a review of the department's mission and structure. Next, the report provides some context for the FY2020 President's budget request. It then discusses the concept of the HHS budget as a whole, in comparison to how funding is provided to HHS through the annual appropriations process. The report continues with a breakdown of the HHS request by operating division. An appendix summarizes the mission of each HHS operating division and identifies additional agency-level resources related to the FY2020 budget request.
