Idaho Medicaid spending on Temporary National Codes (Non-Medicare) services jumps 10.4% in 2024

Idaho’s Medicaid payments reached $61,449,554 in 2024 for services billed under the Temporary National Codes (Non-Medicare) category, according to data from the U.S. Department of Health and Human Services Medicaid Provider Spending database. This represented a 10.4% increase over 2023, when claims for these services totaled $55,655,571.

Medicaid is managed by the states but receives joint funding from both federal and state governments. It provides health coverage for low-income people, seniors, children, and people with disabilities, making it one of the largest components of the national health care system.

Because taxpayer resources support Medicaid, changes in local billing show how public health funds are distributed throughout a community.

The Temporary National Codes (Non-Medicare) category covers several types of Medicaid-billed services, identifiable by the care rendered and based on specific HCPCS and CPT code ranges. Each claim is assigned to one service category through uniform prefix and number guidelines, helping ensure services are grouped competitively and not double counted over time.

When relevant, categories combine multiple service types. These groupings reflect related services commonly billed under Medicaid together, such as office visits, diagnostic tests, or therapeutic procedures.

From 2019 to 2024, Idaho Medicaid payments for Temporary National Codes (Non-Medicare) services increased by $18,198,371, a 42.1% gain. Certain periods saw greater annual jumps, including notable increases in 2020 and 2023.

While such Medicaid spending was distributed statewide, most payments were concentrated in a handful of ZIP codes. In 2024, the largest sums went to ZIP Code 83713 ($19,902,125, or 32.4% of the total), ZIP Code 83301 ($18,457,217, or 30%), and ZIP Code 83814 ($1,575,700, or 2.6%).

The three leading ZIP codes together made up 65% of all Idaho Medicaid spending for Temporary National Codes (Non-Medicare) in 2024.

Statewide Medicaid payments for all claims categories went up 7.6% between 2023 and 2024.

While spending rose across multiple categories, the Temporary National Codes (Non-Medicare) category was among the three largest in Idaho by payment totals for 2024.

According to the Centers for Medicare & Medicaid Services, federal and state Medicaid spending totaled about $871.7 billion in fiscal year 2023, an estimated 18% of total national health expenditures. That marks a steep rise from $613.5 billion in 2019, before the COVID-19 pandemic.

This increase amounts to nearly 40% growth in several years, due largely to expanded enrollment and increased usage during and after the pandemic.

Recent federal budget decisions under the Trump administration feature prominent proposals aimed at cutting federal Medicaid funding and restructuring the program. The “One Big Beautiful Bill Act” signed into law in 2025, for instance, aims to reduce federal Medicaid spending by over $1 trillion in the next decade and introduces elements such as work requirements and higher cost-sharing, with potential effects on coverage and state funding responsibilities. These adjustments are expected to shift more cost burdens to states and may constrain federal Medicaid growth, while the program continues supporting tens of millions of Americans.
