According to the Centers for Medicare & Medicaid Services, Medicaid spending from both federal and state sources reached approximately $871.7 billion in fiscal year 2023, representing about 18% of the nation’s total health expenditures. This is a significant increase from roughly $613.5 billion in 2019, ahead of the COVID-19 pandemic.

This growth—about 40% in a few years—was largely driven by increased enrollment and service utilization during and after the pandemic.

Federal budget measures during the Trump administration introduced major proposals to decrease federal Medicaid funding and restructure the program. For instance, the “One Big Beautiful Bill Act,” enacted in 2025, is expected to reduce federal Medicaid spending by over $1 trillion over the next decade and enforces requirements like work documentation and greater cost-sharing, potentially reducing access and financial support for certain populations. These changes could increase state-level financial responsibility and constrain federal support growth, even as the program continues to serve millions across the country.
