According to data from the U.S. Department of Health and Human Services Medicaid Provider Spending database, Medicaid payments in Wisconsin reached $28,992 for Diagnostic Radiology Services in 2024, reflecting a 15.6% jump from $25,071 in 2023.
Medicaid is a public insurance program operated by the states and funded through both federal and state contributions. The program insures low-income individuals and families, seniors, children and those with disabilities, making it a major component of the U.S. health care system.
Because the program is taxpayer-funded, shifts in Medicaid billing offer insights into how local public health dollars are spent.
The “Diagnostic Radiology Services” category includes a collection of services identified by standardized HCPCS and CPT code prefixes and number ranges. For this review, each billing code was assigned once to a single service group, allowing analysis of related services without duplication and ensuring stable rankings over time.
Certain categories, where applicable, bring together several types of procedures. This can include combinations of services frequently grouped in Medicaid claims, such as office visits, diagnostic assessments and therapeutic interventions.
Between 2019 and 2024, Medicaid disbursements for the Diagnostic Radiology Services category in Wisconsin rose by $21,241—an increase of 274%. Some years, including 2022 and 2023, saw especially strong annual growth.
Though these payments spanned the state, the majority were highly concentrated in a few ZIP codes in 2024. ZIP Code 54901 received the largest share at $19,584, making up 67.6% of the statewide total for these services.
Altogether, the leading ZIP code was responsible for 67.6% of all Medicaid spending for the Diagnostic Radiology Services category in Wisconsin that year.
By comparison, Medicaid payments across all service types increased by 7.5% between 2023 and 2024.
Diagnostic Radiology Services ranked as one of the top 27 Medicaid service categories in Wisconsin for total payments in 2024.
According to the Centers for Medicare & Medicaid Services, combined federal and state Medicaid expenditures totaled about $871.7 billion in fiscal year 2023—roughly 18% of all national health expenditures—up significantly from approximately $613.5 billion in 2019, prior to the COVID-19 pandemic.
This reflects an increase of nearly 40% over a short period, mainly attributed to higher enrollment and greater service use during and after the pandemic.
Recent federal budget measures under the Trump administration have featured extensive proposals to decrease federal Medicaid support and revise program funding. For instance, the “One Big Beautiful Bill Act,” signed in 2025, aims to cut federal Medicaid spending by over $1 trillion over 10 years and introduces requirements like work standards and higher cost-sharing, which may reduce coverage and funding for certain Medicaid recipients. These policy shifts are anticipated to increase costs for states and place constraints on federal support, even as Medicaid continues to serve millions of Americans.
