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 U.S. Virgin Islands for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to U.S. Virgin Islands 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. U.S. Virgin Islands (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 Medicare revenue is small in absolute scale at Total Medicare revenue: $56K and there is no recorded Medicaid activity (none (no Medicaid billing on file)), making the practice effectively single‑payer with Medicare as the only public payer on file. That concentrated payer footprint means any shifts in Medicare case volume or reimbursement would disproportionately affect total revenue.

The NPI was enumerated on 2006-05-24 (~20 years ago), indicating long tenure in the Medicare program despite modest lifetime Medicare receipts. Long enumeration combined with low total revenue suggests this clinician either bills infrequently to Medicare or practices primarily outside fee-for-service Medicare.

Revenue concentration is high: the precomputed top 3 Medicare codes account for 52.3% of Medicare revenue, driven by 00811 (22.0%), 00731 (18.2%), and 00670 (12.2%). This concentration signals a heavy reliance on a small set of anesthesia service types for revenue generation rather than a broad, balanced mix of procedure codes.

The code mix points to a service-line centered on anesthesia for endoscopic gastrointestinal procedures and some higher-complexity surgical cases: 00811, 00731, and 00813 are all endoscopy/anesthesia codes, while 00670 and 01230 indicate participation in extensive spine and open femur procedures. Ancillary procedure codes such as 36620 (arterial line monitoring), 76937 (ultrasound guidance), and 64447 (femoral nerve injection) appear in the top list but at much smaller shares, consistent with an anesthesiology practice that also provides intraoperative monitoring and regional anesthesia.

Competitive standing is mixed by code: 00731 ranks #1998 of 39088 providers nationally (95th percentile; notably above typical national volume), which suggests this provider is relatively active nationally for that specific upper GI endoscopy anesthesia service. By contrast, several other codes show only typical or modest activity (for example, 00670 ranks #2557 of 4713 providers nationally (38th percentile; typical, unremarkable volume)), so the provider’s national prominence is concentrated in a narrow set of services rather than broad dominance.

Several codes appear at very different percentile positions, indicating uneven market participation across service types: 00811 ranks #2251 of 30986 providers nationally (93th percentile; typical, unremarkable volume), 01230 ranks #79 of 982 providers nationally (91th percentile; typical, unremarkable volume), while 00790 and 00840 both appear with 0th percentile; typical, unremarkable volume. These contrasts show pockets of relatively high ranked activity alongside many services where the provider is a modest participant.

Ancillary and procedure-support services account for only small shares of Medicare revenue but demonstrate the provider supplies monitoring and guidance services consistent with perioperative anesthesia care: 36620 accounts for 2.2% of Medicare revenue, 76937 for 0.6%, and 64447 for 1.0%. The presence of these codes supports an operational model that includes invasive monitoring and ultrasound‑guided procedures in addition to routine anesthetic care.

From a business-risk and opportunity perspective, dependence on a few high‑share anesthesia codes (top 3 = 52.3%) combined with an absence of Medicaid billing means this provider has concentrated exposure to Medicare case mix and volumes. The relatively high national standing on 00731 (notably above typical national volume) suggests a competitive strength in upper GI endoscopy anesthesia that could be a focal point for payer negotiations or network placement, but total revenue scale remains small at $56K overall.
