Medicaid, a public health insurance program administered by each state and funded through both state and federal governments, covers low-income populations, older adults, children and those with disabilities. It remains one of the largest sectors within the U.S. health care system.
Because Medicaid is funded by taxpayers, fluctuations in local billing highlight how public resources for health care are distributed within a community.
The “Evaluation and Management” group includes certain Medicaid-billed services categorized by the type of clinical care provided, determined through adopted HCPCS and CPT billing codes. In this study, each specific code was matched with a single service group using standardized code ranges and prefixes, which helped combine similar services, prevent duplicate counting and maintain consistency in tracking rankings over time.
Evaluation and Management placed fifth in Colusa among Medicaid service categories by payment volume for 2024, even as growth occurred across multiple categories.
Across California, the Evaluation and Management group stood second in total Medicaid payments for 2024.

Centers for Medicare & Medicaid Services data show combined federal and state spending for Medicaid rose to approximately $871.7 billion in fiscal year 2023. That sum represented about 18% of nationwide health expenditures and marked an increase from $613.5 billion in 2019, before the COVID-19 pandemic.
This surge equates to about 40% higher spending over the recent span, influenced mostly by expanded enrollment and greater service use linked to the pandemic and its aftermath.
Major budget measures enacted during the Trump administration include proposals to trim federal Medicaid spending and modify the program. The “One Big Beautiful Bill Act,” signed into law in 2025, is estimated to trim over $1 trillion in federal funding for Medicaid across the coming decade and includes changes like tightening work requirements and upping cost-sharing, which could restrict coverage for some beneficiaries and shift funding pressure onto states, even as Medicaid continues serving tens of millions.
