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

Why is the Medicaid comparison limited to Unspecified Location 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. Unspecified Location (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.

Key Findings

This provider’s Medicare footprint is very small in absolute terms: total Medicare revenue is $7.3K and there is no Medicaid billing on file, so the practice is effectively single‑payer (Medicare) in the available data. The absence of any Medicaid claims in the Top 25 Medicaid list confirms no recorded Medicaid revenue.

Revenue is highly concentrated: the precomputed top 3 Medicare codes account for 94.7% of total Medicare revenue, driven primarily by 99204 ($3.1K, 30 claims, $103 avg paid/claim, 42.3% of Medicare revenue), 99214 ($2.8K, 33 claims, $86 avg paid/claim, 38.9%), and 87428 ($992, 16 claims, $62 avg paid/claim, 13.6%). This concentration indicates most Medicare dollars come from a very small set of services rather than a broad mix of billings.

The code mix and the provider’s listed taxonomy (Medical Physician Assistant) point to an outpatient primary‑care or clinic workflow that combines office evaluation and management visits with targeted infectious disease testing: 99204 and 99214 are new and established office E/M codes, and 87428/87426 are antigen assays for SARS–CoV–2/influenza. Together these codes suggest the practice provides evaluation of new and returning patients and also performs point‑of‑care or send‑out respiratory viral antigen testing.

Competitive standing by code is modest and not suggestive of market dominance: 99204 ranks #119284 of 227068 nationally (46th percentile) and 99214 ranks #385096 of 479517 (19th percentile), both characterized in the data as "typical, unremarkable volume for this code." The COVID/influenza test 87428 ranks #7190 of 10591 (28th percentile) and 87426 sits at #16915 of 17750 (0th percentile), so the provider is a low‑to‑moderate volume participant nationally for these services.

Operational detail in the claims shows a close split between new and established patient E/M activity: 99214 has slightly more claims (33) than 99204 (30) but a lower avg paid/claim ($86 vs $103), producing comparable revenue contributions of $2.8K and $3.1K respectively. That pattern is consistent with a small outpatient panel where both new and follow‑up visits contribute materially to revenue rather than a practice concentrated entirely on one visit type.

Although the NPI has long tenure—enumerated on 2005-11-15 (~21 years ago)—the low aggregate Medicare revenue ($7.3K) and limited claim counts indicate a small billing footprint despite long enrollment. Longstanding enrollment combined with low utilization suggests this clinician may practice part‑time, be recently active in Medicare billing only intermittently, or operate in a setting where Medicare patients are a minority of the overall caseload.

All top codes are described in the source as "typical, unremarkable volume," including one code at the extreme low end (87426 noted at the 0th percentile), which means the provider does not appear as a statistical outlier in utilization patterns; rather, the data reflect limited scale. Given the concentration (94.7% from the top three codes) and modest national percentiles, caution is warranted in generalizing service complexity or market role from these Medicare records alone.

Medicare: Competitive Analysis & Benchmarks

How this provider's Medicare billing volume and revenue compare to other providers nationally and within its state, across 4 CPT/HCPCS codes. Note: this provider's state, "XX," is a placeholder CMS uses when a provider's practice-location state wasn't reported — not a traditional US state; the State panel below benchmarks against other providers coded under the same designation.
