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

The provider’s CPT mix is consistent with a diagnostic radiology practice that emphasizes high-volume CT imaging and targeted vascular studies: top codes include 74178 (CT abdomen/pelvis studies), 71271 (LDCT chest screening), and 75635 (CT angiography of the abdominal aorta and iliofemoral arteries), alongside MRI brain and spine codes and several duplex vascular ultrasound codes. This distribution aligns with the listed taxonomy, Diagnostic Radiology Physician, and suggests an operational footprint built around cross-sectional CT services, lung-cancer screening, and vascular imaging.

Revenue concentration is notable at the code level: the precomputed top-3 Medicare codes account for 34.2% of this provider’s total Medicare revenue, with 74178 generating $42.2K (12.9%), 71271 generating $40.6K (12.4%), and 75635 generating $29K (8.9%) of Medicare revenue. This indicates a meaningful dependence on a small set of imaging procedures for a large share of billing.

This provider is effectively single-payer in observed claims: lifetime Medicare revenue is $391K while Medicaid is none (no Medicaid billing on file), so all recorded public-payer volume is Medicare. That concentration increases exposure to Medicare policy and reimbursement changes and limits insight into payer diversification or Medicaid-dependent service lines.

Competitive standing on key procedures is strong and in some cases extreme: 71271 ranks #101 of 8424 providers nationally (99th percentile; extreme outlier) and 75635 ranks #9 of 2469 providers nationally (100th percentile; extreme outlier), indicating nationally unusually high volume for LDCT lung screening and abdominal CTA. 74178 also ranks highly at #272 of 11397 providers nationally (98th percentile; notably above typical national volume for this code), reinforcing that CT-based services are a competitive strength.

Outside those top outlier codes, the provider’s volume is more typical for many imaging services: for example, 93925 (duplex arterial scan) ranks #645 of 10098 (94th percentile; typical, unremarkable volume) and 70553 (brain MRI with and without contrast) ranks #4601 of 11271 (59th percentile; typical, unremarkable volume). This mix suggests the practice pairs a few very high-volume, specialty CT services with a broader baseline of standard radiology work at expected national volumes.

The provider’s NPI tenure indicates an established presence: NPI enumerated (registered) 2007-11-15 (~19 years ago), which supports the likelihood of sustained referral relationships and operational stability in the local market. Long enumeration combined with the high national ranks on specific CT codes suggests an entrenched service line rather than a short-term billing spike.

The absence of Medicaid billing on file (none below) prevents assessment of the provider’s role in Medicaid networks or in-state public payer market share, and it limits conclusions about access for Medicaid populations. For payers or competitors analyzing local capacity, this means Medicaid-side capacity and competitiveness remain unknown and should be confirmed through state claims or network rosters if Medicaid market position is material.
