From the summary:
Beginning in fiscal year (FY) 2020, states will face increased costs for the Children’s Health Insurance Program (CHIP). The 23-percentage point increase in the federal CHIP matching rate—included in the Affordable Care Act (ACA)—will be reduced in FY 2020 and fully phased out in FY 2021. FFIS estimates that state costs could increase by approximately $4.3 billion (302%) to maintain total spending, although several factors remain uncertain.
