Medicaid is a public insurance program overseen by states and funded through contributions from both federal and state governments. The program offers coverage to low-income residents, seniors, children, and individuals with disabilities, making it a key component of the U.S. health care landscape.
Since Medicaid payments are taxpayer-funded, fluctuations in community billing levels illustrate how public health care resources are distributed locally.
The “National Codes Established for State Medicaid Agencies” designation groups Medicaid-billed services according to the type of care, based on standardized HCPCS and CPT code sets. For this report, each billing code was assigned to one service category using consistent numeric ranges and code prefixes, so related care types could be tracked together without double-counting and with accurate rankings over time.

The Centers for Medicare & Medicaid Services report that combined state and federal Medicaid spending amounted to about $871.7 billion for fiscal year 2023, making up around 18% of the nation’s health expenditures—up sharply from around $613.5 billion in 2019, before the pandemic.
This jump marks roughly 40% growth over just a few years, fueled primarily by higher enrollment and increased service use during and following the COVID-19 pandemic years.
Major federal budget legislation during the Trump administration introduced significant plans to cut federal Medicaid funding and restructure the program. For example, the “One Big Beautiful Bill Act,” signed in 2025, is forecast to reduce federal Medicaid funding by over $1 trillion in the next decade, instituting new work requirements and greater cost-sharing that could lower coverage and funding for some beneficiaries. These policy changes are likely to place more of the funding burden on states and may constrain federal Medicaid growth even as the program serves tens of millions nationwide.
