Centers for Medicare & Medicaid Services data show total federal and state Medicaid spending reached about $871.7 billion in fiscal 2023, representing nearly 18% of all U.S. health care spending, a notable increase from $613.5 billion in 2019, before the COVID-19 pandemic.

This is a climb of approximately 40% over just several years, chiefly due to expanded enrollment and increased usage following the pandemic.

Major recent federal legislation enacted under the Trump administration aims to significantly curtail federal contributions to Medicaid and alter program structure. For example, the “One Big Beautiful Bill Act,” passed in 2025, is projected to slash federal Medicaid outlays by over $1 trillion through the next decade, adding requirements such as mandatory work enrollment and expanded cost-sharing. These changes are expected to shift additional expenses to state governments and restrict federal Medicaid growth, affecting coverage for some enrollees as the program continues to serve tens of millions.
