Indiana Medicaid spending reached $100,985 for services in the Diagnostic Radiology Services category in 2024, based on data from the U.S. Department of Health and Human Services Medicaid Provider Spending database. This represented a 144.6% jump compared to 2023, when $41,279 was submitted in claims by providers.
Medicaid is a public insurance program managed by state governments and funded jointly by federal and state resources. It supports low-income residents, families, seniors, children, and individuals with disabilities, making it a major component of the U.S. health system.
Because Medicaid is taxpayer-funded, shifts in local billing activity reflect changes in how public health care resources are distributed across communities.
The “Diagnostic Radiology Services” category includes Medicaid-billed services grouped by care type, defined using HCPCS and CPT code groupings. For this analysis, each billing code corresponded to a single service category through standardized code prefixes and numerical ranges, making it possible to track connected services together without duplicating counts and to maintain proper rankings.
Some categories can cover a range of service types. In these situations, the category includes related types of care frequently billed together via Medicaid, such as office visits, diagnostic testing or therapeutic interventions.
From 2019 to 2024, Indiana Medicaid payments related to the Diagnostic Radiology Services category rose by $59,732, reflecting a 144.8% increase. Growth in this category quickened during particular periods, with notable year-over-year surges in 2020 and 2023.
Although spending attributed to the Diagnostic Radiology Services category was spread statewide, the majority of payments were concentrated in a few ZIP codes. In 2024, the ZIP codes with the highest Medicaid payments for these services were 46815 at $93,850 (92.9% of the total), 46402 at $6,067 (6% of the total), and 46217 with $722 (0.7% of the total).
The combined total from these leading three ZIP codes accounted for 99.7% of all Indiana Medicaid payments connected to the Diagnostic Radiology Services category that year.
Statewide Medicaid payments across all claim categories went up 19.6% between 2023 and 2024.
While Medicaid spending increased in several service categories, Diagnostic Radiology Services ranked among the top 25 service categories statewide by total payments in 2024.
The Centers for Medicare & Medicaid Services reports that federal and state Medicaid spending combined reached about $871.7 billion in fiscal 2023, accounting for roughly 18% of national health costs. This has surged from approximately $613.5 billion in 2019, prior to the COVID-19 pandemic.
This rise amounts to a roughly 40% increase in just a few years, driven mainly by expanding enrollment and greater utilization during and after the pandemic.
Recent federal budget measures under the Trump administration have featured major plans to reduce federal Medicaid spending and alter the structure of the program. Measures like the “One Big Beautiful Bill Act,” enacted in 2025, are projected to cut more than $1 trillion from Medicaid over the next decade while implementing work requirements and higher cost-sharing. These changes could limit coverage and funding for certain beneficiaries, shifting more financial responsibility to states and slowing federal Medicaid growth even as the program continues to serve tens of millions of Americans.
