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 Armed Forces Pacific for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Armed Forces Pacific 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. Armed Forces Pacific (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 single‑payer: total Medicare revenue is $13.5K and there is no Medicaid billing on file, so all reported public-payer activity in the dataset is Medicare-based. That scale is small in absolute terms, indicating this NPI is a low‑revenue Medicare contributor rather than a high-volume billing entity.

Revenue is highly concentrated: the precomputed top‑3 Medicare codes account for 75.2% of the provider's Medicare revenue, with 99214 contributing $4.8K (35.9%), 99204 contributing $3.5K (26.3%), and 87811 contributing $1.8K (13.0%). This concentration means a few service types—office E/M visits and SARS–CoV–2 immunoassay testing—dominate the practice’s Medicare billing.

The code mix points to an outpatient, office-based practice model that also performs point-of-care infectious disease testing: 99214 and 99204 are evaluation and management office visits (established and new patients respectively), while 87811, 87804, and 87880 are rapid immunoassays for SARS–CoV‑2, influenza, and strep. Ancillary services appear limited but present (for example, 71046 chest x‑ray at $405, 27 claims), suggesting basic imaging capability or access to radiology within the outpatient workflow.

Competitive standing across codes is generally modest. 99214 is characterized as "typical, unremarkable volume" and ranks in the 34th percentile nationally, 99204 is "typical, unremarkable volume" at the 57th percentile, while infectious-testing codes show relatively stronger standing with 87811 described as "typical, unremarkable volume" at the 72th percentile and 87804 at the 81th percentile; overall this provider is not a dominant national player on major E/M codes but has comparatively higher relative activity in rapid infectious-disease testing.

Operational volume is limited and uneven: claim counts are modest (e.g., 62 claims for 99214, 39 for 99204, and 81 for 87804), and many listed codes have low claim counts and low dollar impact (for example 81003 produced $36 from 18 claims and 96372 produced $112 from 14 claims). These counts and dollar amounts reinforce that patient throughput and per-code revenue are small, so shifts in a few services could materially change the revenue profile.

Tenure on file is moderate: the NPI was enumerated 2017-04-12 (~9 years ago), indicating the provider has been active under this NPI for multiple years but is not a long-tenured multi-decade registrant. That tenure supports the observed billing pattern as established rather than transient.

From a risk and business-impact perspective, the combination of low absolute Medicare revenue ($13.5K) and heavy dependence on a few codes (top 3 = 75.2%) creates exposure to changes in demand or reimbursement for office E/M and rapid infectious testing. For payer or network planning, this suggests the provider is a small-volume outpatient resource with particular utility for point-of-care infectious testing but limited overall Medicare revenue footprint.
