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 District of Columbia for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to District of Columbia 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. District of Columbia (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 is effectively a Medicare-only biller: total Medicare revenue is $399.1K and there is no Medicaid billing on file. The absence of any Medicaid claims on record makes the provider single‑payer in practical terms and concentrates commercial/Medicaid exposure outside the dataset.

Revenue is highly concentrated in a small set of services: the precomputed top-3 Medicare codes account for 60.7% of total Medicare revenue, led by 99214 at $106.9K (26.8%), followed by 93886 at $69.6K (17.4%) and 93890 at $65.6K (16.5%). This concentration means a majority of income depends on a narrow mix of office E/M and vascular imaging codes.

The code mix points to a neurology practice that pairs outpatient evaluation-and-management visits with in-office vascular diagnostic imaging: primary revenue drivers include 99214 (office established E/M) and multiple Doppler/duplex vascular ultrasound codes (93886, 93890, 93880, 93892). The prominence of these diagnostic vascular procedures alongside higher‑level E/M visits suggests the practice operates as a clinical neurology service with an on-site vascular testing capability or close access to vascular imaging workflows.

Competitive standing on core E/M services is strong: 99214 ranks #10681 of 479517 (98th percentile; notably above typical national volume for this code), indicating the provider sees far more established-patient moderate-complexity visits than most peers nationwide. By contrast, higher-complexity new-patient E/M activity is also elevated—99204 ranks #1912 of 227068 (99th percentile; extreme outlier, far above typical national volume for this code)—which may reflect an unusually large new-patient intake or referral flow.

Vascular imaging performance is mixed but overall notable: 93886 ranks #39 of 682 (94th percentile; typical, unremarkable volume for this code) and 93890 ranks #20 of 278 (93th percentile; typical, unremarkable volume for this code), while 93880 ranks #641 of 21316 (97th percentile; notably above typical national volume for this code). In plain terms, the provider is comparatively active among peers who perform these vascular studies, with some codes showing above‑average national standing and others appearing in the typical range for that procedure.

The practice’s revenue profile includes several mid‑level and high‑level E/M codes (99214, 99204, 99215, 99205) alongside procedure revenue, which suggests both longitudinal outpatient management and episodic diagnostic work. This blend can support stable per‑patient revenue but also concentrates financial risk in the diagnostic testing line if referral or utilization patterns shift.

Given the enrollment date of NPI 2006-02-02 (~20 years ago), the provider appears to be an established clinician with long tenure in Medicare billing. That longevity supports the interpretation that the observed billing patterns are persistent rather than transitory.

From a payer-facing perspective, the lack of Medicaid billing represents both a limitation and an opportunity: current activity is concentrated in Medicare ($399.1K) with no Medicaid presence, so payers and networks assessing access for Medicaid populations should note the absence of in-state Medicaid claims. Any effort to evaluate competitive positioning or network adequacy should treat this provider as a Medicare-centric resource with limited Medicaid availability in the record.
