In 2024, Costa Mesa Medicaid providers billed a total of $47,969,928 for services categorized under Temporary National Codes (Non-Medicare), according to the U.S. Department of Health and Human Services Medicaid Provider Spending database. This figure represents a rise of 98.9% over 2023, when $24,118,383 was claimed for these services.
Medicaid operates as a state-managed public health insurance program with funding from both federal and state governments. It serves diverse groups including low-income individuals, families, seniors, children and those with disabilities, making up one of the largest segments of the nation’s health care system. More details about Medicaid financing are available at the Commonwealth Fund.
Because these Medicaid payments stem from taxpayer revenue, fluctuations in local billing patterns reflect how public health funding is distributed in the area.
The “Temporary National Codes (Non-Medicare)” grouping encompasses a set of Medicaid services distinguished by procedure type, defined with HCPCS and CPT code clusters. For the analysis, billing codes are mapped to one service category via alphabetic prefixes and number ranges to group related services, prevent duplicating counts, and maintain precise year-over-year rankings.
Spending increased in multiple Medicaid service types, but in Costa Mesa, Temporary National Codes (Non-Medicare) received the highest overall payments for 2024.
At the state level, the Temporary National Codes (Non-Medicare) grouping was the seventh largest by payment total in California in 2024.
Over the last five years leading up to 2024, Medicaid claims for Temporary National Codes (Non-Medicare) rose by $47,497,367 in Costa Mesa, equivalent to a 10051.1% jump. Spending growth notably sped up in certain intervals, especially in 2023 and 2022.
While payments for these services were recorded throughout Costa Mesa, claim volumes were heavily concentrated within a few ZIP codes. In 2024, ZIP code 92627 led with $47,507,633 in related payments, while 92626 saw $462,294. Combined, these two areas accounted for 100% of the city’s Medicaid payments under Temporary National Codes (Non-Medicare) that year.
Within this service grouping, a small number of individual billing codes accounted for the majority of Medicaid spending.
Comparatively, payments linked to Temporary National Codes (Non-Medicare) climbed by 98.9% in Costa Mesa between 2024 and 2023, outpacing the 69.5% gain reported across all Medicaid service categories in the city within the same span.
According to the Centers for Medicare & Medicaid Services, combined federal and state Medicaid expenditures amounted to approximately $871.7 billion for fiscal 2023. That figure represented around 18% of national health spending and a substantial rise from about $613.5 billion in 2019 before the COVID-19 public health emergency.
This increase translates to roughly 40% growth over several years, largely driven by bolstered enrollment numbers and heavier utilization during and after the COVID-19 pandemic.
Recent federal budget acts passed under the Trump administration introduced major plans to cut federal Medicaid support and restructure the program. For instance, the “One Big Beautiful Bill Act,” enacted in 2025, is set to reduce federal Medicaid expenditures by more than $1 trillion over the next 10 years. Provisions like work requirements and new cost-sharing rules in the act may lower coverage and decrease funding for some participants. These changes will likely put more financial responsibility on states and could mean overall federal contribution growth slows, even as Medicaid continues to insure tens of millions nationwide.
