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 Armed Forces Pacific for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Armed Forces Pacific 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. Armed Forces Pacific (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 activity is small in absolute scale but highly concentrated: total Medicare revenue is $57.7K, and the precomputed top 3 codes by revenue account for 88.4% of this provider's total Medicare revenue. The three leading codes—01844 ($28.7K, 168 claims, $171 avg/claim), 01924 ($15.5K, 78 claims, $199 avg/claim), and 01916 ($6.8K, 38 claims, $178 avg/claim)—dominate the billing profile. These figures indicate the provider’s Medicare business is driven by a tight set of anesthesia services rather than a broad mix of CPT codes.

Code mix and service-line implication: the top codes are anesthesia services tied to vascular shunt procedures (01844), therapeutic interventional radiologic arterial procedures (01924), and diagnostic arteriography/venography (01916). This pattern suggests the provider operates primarily in vascular/interventional radiology and dialysis-shunt procedural settings, supporting intra-procedural anesthesia for complex vascular access and radiology interventions rather than general ambulatory anesthesia or routine endoscopy.

Revenue concentration detail: 01844 alone represents 49.8% of this provider’s Medicare revenue ($28.7K), making it the single largest revenue driver. With 01844, 01924, and 01916 collectively accounting for 88.4% of Medicare receipts, the provider’s financial exposure is heavily dependent on a narrow set of vascular and interventional anesthesia services.

Payer mix and scale: this provider is effectively single-payer from an observed claims perspective—Medicare revenue is $57.7K and there is no Medicaid billing on file. The absence of Medicaid billing suggests limited engagement with Medicaid populations or with settings that bill Medicaid, so analyses of payer diversification or Medicaid-related risk/strategy are not supported by the data.

Competitive standing for top code 01844: the provider ranks #25 of 1023 providers nationally for 01844 and sits in the 98th percentile, described in the source as an "extreme outlier, far above typical national volume for this code." This ranking indicates a very large relative share of national activity for dialysis/vascular shunt anesthesia compared with peers, identifying a clear niche position at the national level for that specific service.

Competitive standing for related interventional codes: 01924 ranks #24 of 350 providers nationally (93th percentile) and 01916 ranks #32 of 383 providers nationally (91th percentile), both labeled as typical or unremarkable volumes in the source text despite high percentiles. These ranks suggest the provider has above-average activity in interventional radiology and diagnostic arteriography anesthesia when compared to national peers, but outside 01844 the profile is less singularly dominant.

Other observed Medicare services and relative modesty: codes with lower contributions such as 01920 ($4.4K, 21 claims, 25th percentile) and 00812 ($2.3K, 19 claims, 44th percentile) show the provider also bills for coronary angiography anesthesia and screening colonoscopy anesthesia at modest volumes. Those lower-percentile ranks indicate that, apart from the vascular-shunt niche, the provider’s involvement in broader anesthesia categories is moderate or below the high-volume national leaders.

Tenure and operational longevity: the NPI was enumerated on 2005-08-18 (~21 years ago), indicating long-standing enrollment and potential sustained practice presence. Coupled with the concentrated revenue around vascular/interventional anesthesia codes, this tenure supports interpretation of an established specialist practice rather than a newly emergent billing pattern.
