"The Social Security Administration (SSA) is responsible for administering a number of federal entitlement programs that provide income support (cash benefits) to qualified individuals. […] In FY2017, SSA's programs are projected to pay a combined $1 trillion in federal benefits to an estimated 68.4 million individuals. [...] Although benefit payments for SSA's programs are considered mandatory spending and thus are not controlled by the annual appropriations process, the agency requires annual discretionary appropriations to carry out its programs and to support the administration of non-SSA programs, such as Medicare, as well as various other priorities. The annual appropriation for SSA's limitation on administrative expenses (LAE) account provides nearly all of the agency's administrative funding. […] The FY2017 President's budget request for SSA's LAE account is $13.067 billion, which includes $1.819 billion for program integrity activities such as continuing disability reviews (CDRs) and SSI non-medical redeterminations. [...] On June 9, 2016, the Senate Committee on Appropriations approved its FY2017 LHHS appropriations bill by a vote of 29 to 1. The Senate bill would provide $12.482 billion for SSA's LAE account. […] On July 14, 2016, the House Committee on Appropriations approved its FY2017 LHHS appropriations bill by a vote of 31 to 19. The House bill would provide $11.899 billion for SSA's LAE account. […] According to SSA and others, recently enacted funding levels for non-program integrity work have contributed to agency delays in processing other workloads, such as pending disability cases at the hearing level of the administrative appeals process"
