Medicaid, a state-run public health insurance program funded jointly by federal and state governments, covers low-income individuals and families, seniors, children and people with disabilities, making it a core component of the U.S. health care system.

As Medicaid is supported by taxpayer funds, changes in local billing amounts indicate shifts in how public health dollars are distributed within the community.

The “National Codes Established for State Medicaid Agencies” category encompasses services grouped by care type, organized around defined HCPCS and CPT code ranges. For the analysis, each billing code was assigned to a single service group using code prefixes and numeric intervals, ensuring comparable service trends, avoiding duplication, and maintaining consistent rankings over time.

While Medicaid expenditures rose in several categories, National Codes Established for State Medicaid Agencies was the second highest in Irvine by total Medicaid payments in 2024.

Across all of California, this same category ranked first in Medicaid payments statewide in 2024.

Spending for these services was spread across Irvine, but the majority occurred in a few ZIP codes. In 2024, the largest totals for this category were in ZIP code 92617 with $6,321,759, 92614 with $3,039,395, and 92618 at $1,324,658. Combined, these top three ZIP codes comprised 91.4% of all Medicaid outlays for this service group within Irvine in 2024.

Within the category, Medicaid payments were primarily attributed to a small number of individual billing codes.

Centers for Medicare & Medicaid Services data show that combined federal and state Medicaid spending reached approximately $871.7 billion in fiscal 2023, accounting for an estimated 18% of the nation’s health care expenses, rising sharply from about $613.5 billion in 2019 before the COVID-19 pandemic.

The increase amounts to about 40% growth in recent years, primarily due to broadened enrollment and increased health service use during and following the pandemic.

Recent federal budget acts during the Trump administration have proposed major reductions in federal Medicaid spending and restructuring of the system. The “One Big Beautiful Bill Act,” signed into law in 2025, is forecast to reduce federal Medicaid outlays by $1 trillion over the next decade, instituting changes such as work requirements and greater cost-sharing that may reduce access and funding for some. These adjustments are expected to push more financial responsibility to states and restrict federal Medicaid support growth, although the program will continue to cover millions nationally.
