"Section 4002 of the Affordable Care Act (ACA, P.L. 111-148, as amended) established the Prevention and Public Health Fund (PPHF, or 'the Fund') and funded it with a permanent annual appropriation to be administered by the Secretary of Health and Human Services (HHS). The PPHF authority directs the HHS Secretary to transfer amounts from the Fund to HHS agencies for prevention, wellness, and public health activities. [...] The Trump Administration budget proposal for FY2018 would transfer $841 million of the $900 million available to the CDC [Centers for Disease Control and Prevention]. The remaining $60 million reflects sequestration. No additional HHS agencies are proposed to receive PPHF funds for FY2018. If PPHF funds were to become unavailable, additional appropriations would be needed to sustain programmatic activities at the levels provided in recent Labor, Health and Human Services, and Education, and Related Agencies (LHHS) appropriations acts. [...] The Congressional Budget Office (CBO) has estimated the budgetary effects of PPHF repeal as proposed by House-passed H.R. 1628.14 CBO estimated budget authority over the 10-year period of FY2017-FY2026 at $12.0 billion, the sum of annual appropriations to the Fund for those years. It estimated outlays (i.e., the amount that would potentially be saved by the repeal) of $8.8 billion for the same period."
