Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or California for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to California only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. California (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

Key Findings

This provider is effectively single‑payer in the available data: there is no Medicare billing on file while total Medicaid revenue is $145.7M, so Medicaid dominates the observable reimbursement picture for this hospital. Analysts should treat Medicaid patterns as the primary lens for assessing operational scale and service mix.

Revenue is concentrated in a small set of Medicaid codes: the top three codes (0510, 90999, and G0463) each account for $7.1M and represent 9.7% apiece of total Medicaid revenue, together accounting for 29.1% of the provider's Medicaid receipts. This level of concentration indicates a few services drive a large share of Medicaid dollars for the facility.

The code mix points to a high-volume hospital outpatient and emergency footprint combined with inpatient/critical services and dialysis: G0463 (337.6K claims) signals very large hospital outpatient clinic throughput, 99283 (97.7K claims) and 99291 (3.5K claims) indicate substantial ED and critical care activity, and 90999 (54.6K claims) identifies dialysis-related services. Together these codes suggest ARROWHEAD REGIONAL MEDICAL CENTER operates as a full‑service acute care center with heavy ED/outpatient clinic demand and ongoing renal care capacity.

ARROWHEAD shows statewide dominance for several service lines based on rank/percentile: 0510 and G0463 both rank #2 in‑state at the 100th percentile (labeled extreme outlier), and 99070 ranks #3 at the 100th percentile, indicating this provider is a major outlier in volume for those specific codes compared with other California providers. These high percentiles support positioning the hospital as a leading state provider for routine outpatient clinic encounters and certain supply‑intensive encounters.

For some specialized or high‑cost services the hospital is a typical or modest participant rather than an outlier: 90999 (dialysis) ranks #107 of 729 (85th percentile, labeled typical), J9035 (bevacizumab) ranks in the 74th percentile, and J9299 (nivolumab) ranks #12 of 20 (42nd percentile). This pattern suggests strong general acute and outpatient volumes but more average statewide participation in certain specialty drug and dialysis services.

Laboratory and diagnostic testing volumes are large and form a material portion of activity: examples include 87633 with 10.9K claims ($3.7M), U0003 with 20.4K claims ($1.6M), 85025 with 212K claims ($1.9M), 80053 with 179.3K claims ($1.8M), and 84443 with 105.3K claims ($1.4M). These high claim counts and corresponding revenues reflect a substantial laboratory and diagnostics throughput consistent with a busy hospital serving a large Medicaid population.

Advanced imaging and procedural capacity is evident in the top Medicaid code list: 74177 (17.3K claims), 70450 (16.9K claims), 71260 (7.3K claims), and 93306 (12.3K claims) all appear in the top codes, indicating robust CT and cardiac imaging capability that supports emergency, inpatient, and outpatient diagnostic workflows. These volumes, combined with the ED and outpatient clinic indicators, are consistent with comprehensive acute care and diagnostic services on site.

The provider has sustained presence and likely institutional stability: NPI was enumerated 2006-11-08 (~20 years ago). Coupled with $145.7M in Medicaid revenue and multiple state‑level extreme outlier rankings, the tenure and scale point to an established regional medical center role rather than a recent or marginal entrant in the state healthcare market.
