Medicaid, a public health insurance initiative funded by state and federal governments together, covers low-income residents, senior citizens, children, and people with disabilities, making it a central part of the U.S. health care delivery system.
Shifts in local billing volume from Medicaid—a taxpayer-supported program—illuminate changes in how public health dollars are distributed throughout the community.
The Evaluation and Management category groups Medicaid-reimbursed services according to care type, following HCPCS and CPT code structures. For this report, service codes were consistently assigned to categories using established prefixes and number ranges, enabling comparisons of similar services over time with accurate ranking and avoiding duplicate counts.
Although Medicaid disbursements rose across various service types, Evaluation and Management held the position of the second-highest total Medicaid payment category in Oroville for 2024.
Statewide, Evaluation and Management was also the second-largest category in terms of total Medicaid payments in California during 2024.
Over the five-year stretch prior to 2024, Evaluation and Management Medicaid payments in Oroville climbed by $3,783,427, representing growth of 111.3%. The pace of growth intensified in certain years—particularly 2023 and 2021, which saw prominent year-over-year gains.
Though Evaluation and Management services were rendered throughout Oroville, billing was heavily centered in a select few ZIP codes. In 2024, ZIP code 95966 received $5,037,875 in payments, while 95965 accounted for $2,144,035; together, these two ZIPs made up 100% of Oroville’s Medicaid Evaluation and Management claims for the year.
A limited set of billing codes generated the majority of Medicaid spending within this category in Oroville.
Comparatively, the 27.8% annual rise for Evaluation and Management Medicaid payments in Oroville between 2023 and 2024 outpaced the 4.2% growth observed across all categories of Medicaid claims citywide during the same time period.
Centers for Medicare & Medicaid Services data show combined state and federal Medicaid expenditures totaled about $871.7 billion in fiscal year 2023, or roughly 18% of national health spending, an increase from $613.5 billion in 2019 before the COVID-19 pandemic.
This marks growth of nearly 40% in just a few years, prompted primarily by more enrollees and increased use of services during and in the aftermath of the pandemic.
Recent federal budget policies from the Trump administration included proposals to cut federal Medicaid funding and change how the program is structured. The “One Big Beautiful Bill Act,” enacted in 2025, is anticipated to reduce federal Medicaid funds by more than $1 trillion over 10 years and implement new policies like work requirements and higher cost-sharing, potentially narrowing coverage and federal support for some participants. The resulting changes are set to transfer more cost responsibility to states even as Medicaid continues to provide coverage for tens of millions in the U.S.
