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

Why is the Medicaid comparison limited to Guam 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. Guam (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 small in absolute terms: total Medicare revenue reported is $50.2K and there is no Medicaid billing on file, so the practice operates effectively as a single-payer (Medicare) billing profile in the available data. The absence of Medicaid claims also means there are no in-state Medicaid code-level comparisons to assess public program mix or dual-eligible activity.

Revenue is highly concentrated in a few services: the precomputed top-3 Medicare codes account for 55.5% of this provider’s total Medicare revenue. Those top three are 77067 ($17.1K, 34.4% of Medicare revenue), 93306 ($7.1K, 14.2%), and 71046 ($3.5K, 6.9%), indicating a narrow set of high-impact procedures driving most collections.

The code mix points to a multi-modality imaging role consistent with the Radiography Radiologic Technologist taxonomy: 77067 and related breast imaging codes (76641, 77065) indicate active screening/diagnostic mammography work, 93306 indicates provision of transthoracic echocardiography services, and 71046 plus many extremity and spine x-ray codes reflect routine general radiography. This combination suggests the operator performs both mammography and broader diagnostic imaging/sonography rather than focusing on a single narrow service line.

Competitive standing for the largest revenue driver is middling nationally: 77067 ranks #6573 of 15198 providers nationally (57th percentile; typical, unremarkable volume), so screening mammography volume is around the national median rather than outlier-level. In other words, the provider contributes a meaningful share of its modest revenue from mammography but is not a dominant national performer on this code.

Echocardiography and some advanced imaging codes show relatively low national volume: 93306 ranks #20386 of 24624 (17th percentile; typical, unremarkable volume), indicating lower-than-average national activity for transthoracic echo, while 71250 (CT thorax) ranks #19534 of 21854 (9th percentile; typical, unremarkable volume), suggesting minimal CT chest work. By contrast, chest radiography 71046 sits at a higher relative position (rank #8181 of 47284, 83th percentile; typical, unremarkable volume), meaning plain chest x-rays are a stronger component of the case mix compared with echo or CT.

The provider’s national ranking profile is heterogeneous across modalities: some routine radiography codes are at or above median national participation (for example 71046 at the 83th percentile), while several ultrasound, echo, and CT codes fall into lower percentiles. This pattern is consistent with a technologist who performs high-volume plain films and mammography locally but has limited contribution to higher-acuity cross-sectional imaging in the national context.

The NPI has long tenure in the system—enumerated on 2006-03-28 (~20 years ago)—so the reported low dollar volumes are unlikely to reflect a newly established billing entity. Given long enumeration with total Medicare receipts of $50.2K, the data indicate a sustained but small-scale imaging practice in Tamuning, GU rather than rapid growth or recent entry.
