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

Why is the Medicaid comparison limited to Puerto Rico 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. Puerto Rico (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

Medicare activity is tightly concentrated in anesthesia for gastrointestinal endoscopic procedures: the top three Medicare CPT/HCPCS codes billed are 00811, 00813, and 00731, which correspond to lower intestinal endoscopy, combined upper/lower intestinal endoscopy, and upper gastrointestinal endoscopy anesthesia respectively. Claim volumes and average payments for these codes — 00811: 327 claims at $102 avg paid/claim; 00813: 207 claims at $130 avg paid/claim; 00731: 145 claims at $109 avg paid/claim — indicate a practice model focused on routine endoscopy anesthesia services. These three codes together drive the provider’s clinical footprint in Medicare.

Revenue concentration is extreme: the precomputed top-three share shows that 95.5% of this provider’s total Medicare revenue is attributable to 00811, 00813, and 00731. Dollar contributions to that total are dominated by 00811 ($33.4K, 41.9%), 00813 ($26.9K, 33.8%), and 00731 ($15.8K, 19.8%), which together sum to the bulk of the $79.8K in reported Medicare revenue. This level of concentration signals that business performance is highly dependent on continued referrals and reimbursement for these specific endoscopy anesthesia services.

Payer mix is effectively single-payer with respect to public programs: lifetime Medicare revenue totals $79.8K and there is no Medicaid billing on file. The absence of Medicaid activity means the provider’s public-pay revenue profile is concentrated entirely in Medicare, which simplifies but also concentrates payer risk and reimbursement exposure. Analysts should treat Medicaid-related market or policy shifts as non-immediate for this provider, while Medicare policy or referral changes would have direct impact.

Competitive standing on key codes is unusually strong at the national level: 00811 ranks #112 of 30986 providers nationally (100th percentile; extreme outlier) and 00813 ranks #22 of 16000 providers nationally (100th percentile; extreme outlier), while 00731 ranks #430 of 39088 providers nationally (99th percentile; extreme outlier). These rank and percentile positions indicate volumes far above typical national peers for the same anesthesia codes, so the provider is a major national outlier on its principal revenue lines despite modest absolute Medicare dollars. For benchmarking, this pattern reflects dominant activity in a narrow service line rather than broad multi-code market share.

Statistical outlier language in the source is confirmed by volume and rank: all three top codes are labeled as extreme outliers or near-extreme (100th and 99th percentiles) and the provider’s claim counts (327, 207, 145) align with that characterization. In plain terms, the provider bills these endoscopy anesthesia codes at volumes that are well above typical national levels, which is relevant for competitor comparison, network contracting, and capacity analysis. These outlier designations should flag the provider for further investigation of referral sources and site-of-service patterns (e.g., ambulatory endoscopy centers).

Tenure is relatively recent: the NPI was enumerated on 2021-09-08 (~5 years ago). Generating $79.8K of Medicare revenue and achieving outlier national ranks on multiple codes within that timeframe suggests rapid accumulation of case volume in the specific endoscopy anesthesia niche. Tenure combined with current volume profile may indicate an expanding or highly focused practice since enumeration.

Operational implications from the claim-level metrics point to a throughput-oriented anesthesia practice supporting GI endoscopy: the mix (high counts on 00811 and 00813, smaller counts on screening colonoscopy 00812 and anorectal 00902) suggests routine coverage of both upper and lower endoscopic procedures rather than broader surgical anesthesia. Average paid/claim rates ($102, $130, $109) plus the claim counts imply regular, repeatable case flow consistent with outpatient endoscopy workflows and predictable reimbursement per encounter. For network planners and revenue analysts, this profile maps to a narrowly specialized service line with stable unit economics but limited diversification.

Concentration creates both opportunity and sensitivity: being heavily dependent on a small set of endoscopy anesthesia codes (95.5% of Medicare revenue) can be advantageous for specialized contracting and operational efficiency, but it also makes the provider’s Medicare revenue vulnerable to changes in endoscopy volumes, referral patterns, or code-level reimbursement. Given there is no Medicaid billing on file, any payer or site-of-service shifts that affect Medicare endoscopy cases would likely have an outsized effect on this provider’s public-pay revenue base.
