This week, our In Focus section reviews Medicaid historical and projected expenditure and enrollment data from the Centers for Medicare & Medicaid Services (CMS) Office of the Actuary. The Office of the Actuary provides annual updates to historical and projected National Health Expenditure (NHE) data. The latest NHE projections were updated in July of this year, with projections through 2025, while an overall fact sheet on historical and projected data was updated on August 10. NHE projections include enrollment data by program and expenditure data by program and category of service, as well as data on business, household, and government spending. Below, we summarize some key takeaways on the Medicaid and CHIP data, looking at historical data from 2014 (the most recent historical year), and projections of enrollment and spending for 2015, 2020, and 2025. By 2025, NHE projects 85.2 million Medicaid and CHIP beneficiaries to account for just under $1 trillion in annual spending.
