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

Why is the Medicaid comparison limited to New Jersey 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. New Jersey (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 single‑payer Medicare practice: total Medicare revenue is $3.6M while there is no Medicaid billing on file. The absence of any Medicaid activity makes payer risk and reimbursement strategy for this NPI driven entirely by Medicare volumes and rates.

Revenue is highly concentrated in a small set of endovascular procedure codes: the top 3 Medicare codes (37227, 37229, 37231) account for 75.4% of this provider's total Medicare revenue. Individually those codes contribute $1.4M (39.0%), $850.4K (24.0%), and $436.6K (12.3%) respectively, signaling dependence on a narrow set of high‑revenue interventions.

The code mix points to a vascular surgery practice with a strong emphasis on endovascular stent and catheter procedures plus routine use of intravascular ultrasound. High‑revenue codes 37227/37229/37231 are complemented by substantial IVUS add‑on activity (37252: 321 claims, $257.1K, 7.3%; 37253: 911 claims, $135.7K, 3.8%), indicating frequent use of intravascular imaging to support interventions.

Several top codes position the provider well above national norms for specific technical services, marking a competitive specialty footprint rather than broad generalist volume: 37227 ranks #3 of 363 providers nationally (99th percentile; extreme outlier), 37252 ranks #14 of 1088 (99th percentile; extreme outlier), and 37253 ranks #9 of 788 (99th percentile; extreme outlier). These rankings suggest the provider is a dominant national outlier for selected interventional vascular procedures.

Imaging and procedural support services are also unusually concentrated: 75630 is ranked #1 of 221 providers nationally (100th percentile; extreme outlier) and 76937 has 257 claims with $9K revenue and ranks #67 of 12234 (99th percentile; extreme outlier). High relative volumes in both radiologic studies and ultrasound guidance imply integrated imaging capability that supports the provider's intervention‑heavy case mix.

While a few endovascular codes are extreme outliers, not all higher‑revenue procedure lines show exceptional national standing. For example, 37231 has 40 claims and $436.6K revenue and ranks #12 of 45 providers nationally (73th percentile; typical, unremarkable volume), and 37238 ranks #16 of 130 (88th percentile; typical, unremarkable volume), indicating a focused specialization in certain procedures rather than uniformly elevated volumes across all peripheral vascular codes.

Office evaluation and management plus moderate sedation are present but represent a very small share of revenue: 99213 has 192 claims and $14.8K revenue (0.4%), 99203 has 82 claims and $7.6K revenue (0.2%), and G0500 accounts for $2.7K (0.1%). This pattern reinforces that procedural/interventional billing, not E/M or sedation, is the primary revenue engine for the practice.

The provider has an established tenure on Medicare, with an NPI enumerated on 2010-03-25 (~16 years ago), which supports the interpretation of these patterns as the output of a sustained, procedure‑focused vascular surgery practice rather than a transient or newly established billing profile.
