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 is enumerated as a Clinical Social Worker and has been active on file since 2013-12-13 (~13 years ago), indicating an established individual practice rather than a newly registered clinician. The tenure supports stable Medicare billing history but does not by itself indicate organizational scale or affiliations.

Medicare is the sole payer on record: total Medicare revenue is $26.4K and there is no Medicaid billing on file. This makes the provider effectively single-payer (Medicare) in the available data, so analyses of payer mix should treat Medicaid as absent rather than underreported.

Revenue is highly concentrated: the precomputed top-3 Medicare codes account for 100.0% of the provider's Medicare revenue, and the single listed code 90837 alone accounts for $26.4K (100.0%). This concentration signals a narrow service mix with most economic activity tied to one long-session psychotherapy code.

Operationally, the dominance of 90837 (psychotherapy, 53+ minutes) suggests the practice focuses on individual psychotherapy sessions of extended duration rather than brief therapy, testing, or case management. The code mix implies a clinical workflow centered on scheduled psychotherapy visits rather than procedure-heavy or ancillary-service lines.

Activity metrics for 90837 show 304 claims at an $87 avg paid/claim, producing $26.4K in Medicare revenue. That claim count and average payment profile are consistent with a steady outpatient psychotherapy caseload rather than episodic/acute-care billing patterns.

Competitive standing for 90837 is modestly above median: the provider ranks #3762 of 15257 nationally (75th percentile) with the plain-English characterization provided as "typical, unremarkable volume for this code." This indicates the clinician is not a national leader in volume but performs above the median peer level for this specific psychotherapy code.

The absence of Medicaid billing on file could reflect non-participation in Medicaid, selection of a patient panel concentrated in Medicare-eligible populations, or administrative billing choices; regardless, it limits the provider's exposure to Medicaid revenue streams and reduces diversification of payer risk. Analysts should treat Medicaid-derived revenue as zero in payer-mix calculations for this profile.

Given the small absolute Medicare revenue ($26.4K) and the single-code concentration into 90837, the provider represents a narrow, psychotherapy-focused practice of modest scale. Strategic or competitive analysis should emphasize behavioral health outpatient services and recognize single-code dependence as a potential operational and revenue concentration risk.
