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

Why is the Medicaid comparison limited to Oregon 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. Oregon (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 a Diagnostic Radiology Physician based in BEND, OR with Total Medicare revenue of $997.3K and no Medicaid billing on file; the record therefore reflects an effectively single-payer (Medicare) billing profile rather than a dual-payer footprint. The absence of Medicaid activity ("none below") means all analyzed revenue and utilization patterns arise from Medicare claims only.

Revenue is highly concentrated in a small set of nuclear medicine/PET services: the precomputed top three Medicare codes account for 60.6% of this provider's total Medicare revenue, driven by 78815 ($320K, 33.7%), A9595 ($178K, 18.7%), and A9552 ($78.1K, 8.2%). This concentration indicates that a majority of dollars billed to Medicare come from PET/ radiopharmaceutical studies rather than a broad mix of low‑value services.

The code mix indicates a service-line specialization in advanced oncologic and cross-sectional imaging: high-revenue PET/CT codes (78815 and 78816) and radiopharmaceutical codes (A9595, A9552) dominate the top revenue list, consistent with an operation focused on PET/CT oncology imaging and tracer administration. Secondary but meaningful volumes in body CT and MRI codes (e.g., 74177, 74183, 72197) suggest the practice also maintains substantial CT/MRI capacity for abdomen/pelvis and pelvis imaging.

Competitive standing in PET/CT: 78815 ranks #214 of 6566 providers nationally (97th percentile; notably above typical national volume), signaling national-level strength and unusually high PET/CT activity for that code. By contrast, A9595 ranks #157 of 528 providers nationally (70th percentile; typical, unremarkable volume), indicating a more modest relative position in usage of that specific tracer, while A9552 ranks #204 of 2411 (91th percentile; typical, unremarkable volume) and contributes meaningfully to overall PET-related revenue.

Multiple cross-sectional imaging codes are statistical outliers, showing the practice operates at unusually high volumes for abdominal/pelvic and thoracic imaging: 74177 ($58.5K, 6.2%) ranks #260 of 23621 (99th percentile; extreme outlier), 74183 ($43K, 4.5%) ranks #61 of 7242 (99th percentile; extreme outlier), 72197 ($40.4K, 4.3%) ranks #70 of 4732 (99th percentile; extreme outlier), and 71271 ($22.1K, 2.3%) ranks #45 of 8424 (99th percentile; extreme outlier). These labels indicate far above-typical national volume for several body CT/MRI services rather than isolated, low-frequency use.

Other nuclear medicine and functional imaging services appear in the mix at lower revenue contributions (for example, 78306 $12.3K, 1.3% and 78830 $15K, 1.6%), reflecting a broader diagnostic nuclear medicine capability beyond PET/CT. Several CPT/HCPCS in the top-25 list (e.g., 78608, 78306, 78830) are present at percentiles that the data describes as "typical, unremarkable" to "notably above typical," supporting the view of an imaging practice with both specialized PET services and routine nuclear medicine offerings.

The payer-concentration profile — Total Medicare revenue $997.3K versus Medicaid: none — creates operational dependency on Medicare volume and reimbursement patterns. That concentration suggests the provider's revenue is more sensitive to Medicare policy or utilization-management changes than peers with mixed payer coverage.

The provider's NPI was enumerated on 2007-05-31 (~19 years ago), indicating a long tenure in Medicare billing; combined with the high-percentile rankings on several advanced imaging codes, this tenure supports the interpretation of an established imaging operation with sustained PET/CT and cross-sectional imaging throughput in its market.
