Medicaid is a joint federal and state public health insurance program that covers low-income families and individuals, seniors, children, and those with disabilities, positioning it as a major component of the U.S. health care system. Funding comes from both federal and state governments together.
Because Medicaid payments are sourced from taxpayer dollars, local changes in submitted billing can highlight how health care funding flows within communities.
The “National Codes Established for State Medicaid Agencies” category organizes Medicaid-billed services by care type, grouped according to standardized HCPCS and CPT codes. Billing data was classified so each code fit a single service group, with consistent code groupings to maintain accuracy in trackable service rankings while preventing duplicates.

This represents an approximate 40% increase over just a few years, primarily attributed to growing enrollment and higher demand throughout and following the COVID-19 pandemic.
Recent congressional budget measures during the Trump administration have included substantive options to cut federal Medicaid resources and reconfigure the program. The “One Big Beautiful Bill Act,” for instance, which became law in 2025, is expected to trim more than $1 trillion in Medicaid spending over 10 years. This law brings changes like work mandates and enhanced cost sharing, potentially reducing both coverage and federal funds for affected beneficiaries. These policy moves may drive increased state responsibility for expenses and limit the expansion of federal support, though Medicaid continues providing services for tens of millions nationwide.
