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

Why is the Medicaid comparison limited to New York 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 York (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

This provider’s billing footprint is very small in scale: lifetime Medicare revenue is $5.9K and there is no Medicaid billing on file, making the NPI effectively single-payer (Medicare) in the available data. Analysts should treat this as a low-revenue profile rather than a multi‑payer practice when assessing network impact or utilization patterns.

The NPI has long tenure — enumerated 2006-09-28 (~20 years ago) — but the Medicare billing activity appears limited despite the long registration, suggesting either part-time clinical activity, coverage-only appearances on claims, or a focused practice with low Medicare volume. Tenure alone does not imply current volume or market influence for this provider.

Revenue is highly concentrated: the precomputed top 3 codes account for 100.0% of this provider’s Medicare revenue. Those codes are 00142 ($2.3K revenue, 38.6% of total Medicare revenue; 19 claims, $120 avg paid/claim), 00812 ($2.2K revenue, 36.5% of total Medicare revenue; 22 claims, $98 avg paid/claim), and 00731 ($1.5K revenue, 24.9% of total Medicare revenue; 13 claims, $113 avg paid/claim).

The code mix indicates a service-line focus on procedural anesthesia for ambulatory or procedural specialties: 00142 corresponds to anesthesia for eye lens procedures, 00812 to anesthesia for screening colonoscopy, and 00731 to anesthesia for upper GI endoscopy. This combination suggests the provider functions primarily as a Certified Registered Nurse Anesthetist supporting ophthalmology and endoscopy cases rather than broad inpatient surgical anesthesia practice.

Competitive standing versus national Medicare peers is modest to low across the top codes. For 00142 the provider ranks #14523 of 19760 (24th percentile; typical, unremarkable volume), for 00812 the provider ranks #7362 of 16489 (53th percentile; typical, unremarkable volume), and for 00731 the provider ranks #31752 of 39088 (13th percentile; typical, unremarkable volume), indicating no dominant market share and generally below‑median participation except near‑median on 00812.

Operational metrics reflect low procedural throughput: claim counts are small (19, 22, and 13 claims for the top three codes) and average paid/claim values are $120, $98, and $113 respectively. Combined with the $5.9K total Medicare revenue, these figures point to a low-volume anesthesia practice where individual procedural engagements drive most of the observed billing.

For payer or contracting analysts, the lack of any Medicaid billing and the concentration of Medicare revenue in three anesthesia codes mean this NPI should be classified as a narrowly focused, low-volume CRNA. If assessing network adequacy or specialist supply, treat the provider as a supplemental anesthesia resource for endoscopy and ophthalmic procedures rather than a high-capacity anesthesia provider.
