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 Wisconsin for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Wisconsin 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. Wisconsin (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.

How current is this data?

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

This provider is effectively a Medicaid-focused operation: there is no Medicare billing on file and total Medicaid revenue on record is $16.8M. The absence of Medicare activity means analyses of its financial and utilization profile should treat Medicaid as the dominant (in practice, sole) public payer for this entity.

Revenue is highly concentrated in a few services: the precomputed top-three Medicaid codes account for 41.4% of the provider's total Medicaid revenue. Those top drivers are U0003 ($2.9M; 25.2% of Medicaid revenue), 99283 ($958.2K; 8.4%), and 96361 ($877.8K; 7.7%), which together form the backbone of reported Medicaid receipts and represent a material share of overall margin exposure.

Emergency department services appear to be a major service line for Medicaid patients: 99283 shows 14.7K claims and $958.2K in revenue (8.4% of Medicaid revenue), 99285 shows 20.3K claims and $729.2K (6.4%), and 99284 shows 13.6K claims and $624.7K (5.5%). The volume and revenue mix across low, moderate, and high ED E/M codes indicate substantial ED throughput and that emergency care drives a meaningful portion of Medicaid billing.

High-throughput infectious-disease testing is a distinguishing feature of this provider’s Medicaid profile: U0003 has 42.1K claims and $2.9M in revenue (25.2% of Medicaid revenue) and is labeled an extreme outlier, ranking #2 of 172 providers in-state (99th percentile). Complementary COVID-related testing U0005 (30.9K claims, $278.2K, 2.5%) also ranks highly (#3 of 132; 98th percentile), underscoring a scaled diagnostic operation with outsized testing volumes relative to peers.

Outpatient clinic and laboratory throughput is elevated across multiple measures: G0463 has 70.5K claims and $352.6K in revenue (3.1%) and ranks #4 of 99 providers in-state (97th percentile), while routine lab panels show large claim counts — 80053 (26.5K claims, $582.6K; 5.1%) and 80048 (24K claims, $408.7K; 3.6%). These figures point to centralized outpatient clinic activity and in-house lab capacity that support both clinical visits and high-volume specimen processing.

Competitive standing is mixed but strong in specific niches: the provider is a statewide leader for high-throughput SARS-CoV-2 testing (U0003 extreme outlier; U0005 notably above typical), while many common lab and imaging codes rank in above-average percentiles (for example, 80053 at the 87th percentile and 80048 at the 93rd percentile) but are described as typical or unremarkable in absolute state volume. This pattern indicates dominance in targeted diagnostic testing alongside broadly solid, but not universally dominant, performance across routine lab and imaging services.

Operational exposure should be noted: multiple very high-count lab codes (e.g., U0003 42.1K claims, 85025 47.6K claims, G0463 70.5K claims) suggest economies of scale around centralized testing and outpatient encounters, but also a sensitivity of Medicaid revenue to changes in testing demand or reimbursement for those concentrated codes. Given that a small set of codes accounts for a disproportionate share of revenue, shifts in policy or demand for these services could materially affect revenue.

The provider has a long-standing presence in the market: the NPI was enumerated on 2006-05-09 (~20 years ago) and the taxonomy is General Acute Care Hospital located in Eau Claire, WI. That tenure, combined with the mix of ED, imaging (e.g., 74177, 70450) and extensive lab work, is consistent with a regional acute-care facility that operates a high-volume outpatient clinic and centralized diagnostics supporting Medicaid populations.
