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.

The Medicare and Medicaid tables are both single current snapshots, not refreshed on a recurring schedule yet.

Key Findings

This provider’s Medicare footprint is small in absolute dollars: total Medicare revenue is $28.6K and there is no Medicaid billing on file, so the practice is effectively single-payer (Medicare) in the available data. The absence of Medicaid billing means analysts should treat all utilization and revenue patterns as Medicare-driven rather than distributed across both public payers.

Revenue is highly concentrated: the precomputed top 3 Medicare codes account for 89.1% of this provider’s total Medicare revenue, driven by 99291 ($20.8K, 72.6% of Medicare revenue), 99233 ($2.5K, 8.8%), and 00731 ($2.2K, 7.7%). This concentration indicates that a small set of high-impact services supplies the vast majority of billed value.

The code mix points to a hospital-based critical care and anesthesia role. 99291 is a critical care service code (first 30–74 minutes) and 99233 is a high-complexity subsequent inpatient/observation E/M; 00731 is anesthesia for upper GI endoscopy. Together these suggest the provider delivers time- and acuity-intensive care in inpatient/ICU and procedural settings rather than a broad outpatient panel of office visits.

Competitive standing on the top revenue driver is modest: 99291 (117 claims, $178 avg paid/claim, $20.8K revenue) ranks #11973 of 71290 providers nationally (83th percentile; typical, unremarkable volume for this code), indicating above-median but not dominant national activity for critical care services. For payers and network planners this implies the provider is a capable, regular performer of critical care services but not a major national outlier or high-volume center for 99291.

The other two top codes show mixed positioning: 99233 (25 claims, $101 avg paid/claim, $2.5K revenue) ranks #109375 of 128818 providers nationally (14th percentile; typical, unremarkable volume for this code), reflecting relatively low comparative activity on high-complexity subsequent inpatient visits, while 00731 (21 claims, $105 avg paid/claim, $2.2K revenue) ranks #18790 of 39088 providers nationally (49th percentile; typical, unremarkable volume for this code), which is near-median for anesthesia during upper GI endoscopy. This split suggests the provider’s strength is concentrated in the primary critical-care code rather than broad, high volumes across inpatient E/M and anesthesia codes.

Supporting codes further confirm a peri-operative/inpatient focus but at low-to-modest volume: 00811 ($1.5K, 5.2% of Medicare revenue) ranks #17046 of 30986 (42th percentile; typical, unremarkable volume), 99232 ($1.1K, 3.7%) ranks #169277 of 177383 (4th percentile; typical, unremarkable volume), and 36620 ($555, 1.9%) ranks #8243 of 12809 (30th percentile; typical, unremarkable volume). These smaller revenue contributors show routine use of lower intestinal endoscopy anesthesia, moderate-complexity subsequent inpatient visits, and arterial catheter procedures consistent with ICU or procedural monitoring, but none indicate outsized service volume.

Tenure data show an established enrollment: NPI was enumerated on 2009-06-22 (~17 years ago), signaling a long-tenured provider in the Medicare program. For contract or credentialing teams this long enumeration suggests sustained participation in Medicare billing even if annual dollar volumes are modest.

For payer/provider analysts considering business implications, the combination of high revenue concentration (89.1% in three codes) and overall Medicare-only billing implies limited diversification of revenue and constrained negotiating leverage. Operationally, value or utilization reviews should prioritize 99291 documentation and time-based critical care elements, while acknowledging that the provider’s overall Medicare spend is small ($28.6K) and not indicative of a large-volume inpatient or anesthesia group.
