    Key Findings

    ALAMEDA HEALTH SYSTEM shows an effectively single‑payer Medicare/Medicaid footprint: there is no Medicare billing on file and total Medicaid revenue is $172.2M, indicating the provider’s reported revenue during the period is dominated by Medicaid rather than a mixed Medicare/Medicaid payer mix. This concentration suggests contracting and utilization reviews should prioritize Medicaid-product lines and reimbursement dynamics.

    Revenue is highly concentrated in a small set of Medicaid codes: the top three codes — 0681 ($21.6M), 99284 ($13M), and J9271 ($11M) — account for 46.0% of the provider’s total Medicaid revenue. That level of concentration indicates that a few service lines (one unspecified by code 0681, ED E/M services, and high‑cost oncology drug administration) drive nearly half of reported Medicaid receipts.

    The code mix points to a high‑volume acute care operation with heavy emergency department and inpatient activity: 99284 shows 199.9K claims and $13M revenue (13.1% of Medicaid revenue), and subsequent inpatient care codes 99231 (125.8K claims, $5.2M) and 99232/99233 also appear in the top 25. These volumes are consistent with large ED throughput and substantial inpatient census and should inform staffing, capacity, and ED-to-inpatient flow analyses.

    ALAMEDA is a material provider of oncology/infusion services: J9271 (pembrolizumab) booked $11M across 821 claims (11.1% of Medicaid revenue) and other infusion/administration codes such as 96365/96374 and J1459 appear in the top 25. The presence of high‑cost biologic drug billing alongside multiple infusion administration codes indicates an established chemotherapy/immunotherapy infusion program contributing meaningfully to Medicaid revenue.

    Imaging and diagnostics represent a meaningful revenue stream and high procedural volume: CT/MRI and cardiac diagnostics appear across the top codes — e.g., 74177 ($4.6M), 70450 ($3.6M), 71260 ($2.6M), 70553 ($1.8M), and the CMP 80053 (176.3K claims, $1.9M). Many of these imaging codes rank well above typical state volumes, implying in‑house advanced imaging capacity that supports both ED and inpatient care.

    Billing for supplies and unclassified drugs is unusually large relative to peers: 99070 has 168.7K claims and $5.4M revenue (5.4% of Medicaid revenue) and J3490 has 79.4K claims and $2.1M revenue; both are flagged as extreme outliers or far above typical state volume. This pattern is consistent with high patient throughput and/or frequent use of billable supplies and unclassified drug entries in ED/inpatient encounters, and it may warrant focused review for payer contract design and cost containment.

    Competitive standing within California is strong on multiple fronts: 0681 ranks #1 of 9 providers in‑state (100th percentile) and 99284 ranks #7 of 1395 providers in‑state (100th percentile, noted as an extreme outlier), while 99231 ranks #2 of 672 (100th percentile). These ranks indicate ALAMEDA is a dominant or major in‑state provider for several high‑volume acute care codes, particularly emergency and inpatient E/M services.

    The provider is longstanding in enrollment and operations: the NPI was enumerated on 2007-05-30 (~19 years ago), indicating nearly two decades of presence in the market. Combined with the large Medicaid footprint and high percentile ranks on multiple codes, this tenure suggests an established operational scale that payers and competitors should account for when assessing network capacity or negotiating Medicaid agreements.
