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

Why is the Medicaid comparison limited to North Carolina 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. North Carolina (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.

Key Findings

ARI ISAACSON is a Vascular & Interventional Radiology physician in CHAPEL HILL, NC with an NPI enumerated on 2006-01-25 (approximately 20 years), indicating long-standing Medicare participation and clinical tenure. The provider's lifetime Medicare revenue is $2.8M, and there is no Medicaid billing on file, making this effectively a single-payer (Medicare-focused) billing profile.

Revenue is highly concentrated in a small number of high-value interventional codes: the three precomputed top Medicare codes account for 88.0% of the provider's total Medicare revenue, signaling reliance on a narrow set of interventional procedures for the bulk of income. This concentration suggests a specialized procedural practice rather than a broad outpatient or primary-care panel.

Code 37243 dominates the revenue mix with $2M in Medicare revenue (69.7% of this provider's total Medicare revenue) and 305 claims; the provider ranks #1 of 271 nationally for this code and is described as an extreme outlier. This implies a major clinical focus on embolization procedures for tumors, fibroids, or organ ischemia and positions the provider as a national outlier in volume for that service.

The next two revenue contributors are 36247 ($354.6K; 12.6% of total Medicare revenue; rank #1 of 903 nationally, extreme outlier) and 37244 ($162.6K; 5.8% of total Medicare revenue; rank #2 of 98 nationally, notably above typical national volume). Together these three codes reinforce a practice centered on angiography and embolization for hemorrhage and targeted vascular occlusion, indicating high specialization in endovascular therapeutic procedures.

Several ancillary and support codes also appear at unusually high national percentiles, including 75774 (rank #5 of 634, 99th percentile), 36248 (rank #5 of 229, 98th percentile), and 75726 (rank #2 of 371, 100th percentile), which suggests the provider performs a high volume of angiographic imaging and radiological supervision components in conjunction with primary interventional services. These patterns point to an integrated procedural workflow where imaging and catheter-based interventions are a consistent part of the case mix.

The absence of any Medicaid billing on file means payer mix is heavily skewed toward Medicare; operational or referral patterns that yield Medicare patients (e.g., older adult population, hospital-based work) are likely driving volume. Analysts should treat this provider as effectively single-payer in public programs and be cautious extrapolating to Medicaid markets.

Multiple codes are characterized as statistical outliers or notably above typical volume (e.g., 37243 extreme outlier; 36247 extreme outlier; 37244 notably above typical), which supports a competitive standing as a dominant national performer for several specialized endovascular services rather than a modest local participant. This national-level dominance on key codes may reflect either a referral hub role or a concentrated procedural practice.

Although the provider bills a few low-revenue items (e.g., J0690, J2930, 76937) and some common E/M or contrast supply codes, these together represent a very small share of total Medicare revenue; the practice’s economics are driven by the high-reimbursement therapeutic angiography and embolization codes rather than routine office visits or supply billing.
