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

Why is the Medicaid comparison limited to South Carolina 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. South Carolina (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 commercial footprint is effectively single‑payer at the state level: Total Medicare revenue is $2.2M while Medicaid billing is recorded as none, so the practice’s public revenue exposure is concentrated in Medicare only. Analysts should treat comparisons and trend work with the understanding that Medicaid activity is not on file for this NPI.

Revenue concentration is high within Mohs-related codes: the precomputed top‑3 Medicare codes (17311, 17312, 17313) account for 49.4% of the provider’s total Medicare revenue. Individually those codes generated $538.9K (26.1%) for 17311, $332.5K (16.1%) for 17312, and $148.4K (7.2%) for 17313, signalling that nearly half of Medicare dollars come from layered excision/Mohs procedures.

The code mix and dollar values point to a Mohs‑focused surgical practice that also performs significant reconstruction and wound repair. High‑revenue reconstructive codes such as 15260 ($130.5K, 6.3%), 14060 ($95.9K, 4.6%) and 14301 ($89.8K, 4.4%) indicate substantial full‑thickness grafts and local flap work following excisions, consistent with a practice that pairs Mohs excision with on‑site reconstruction.

Competitive standing for Mohs is nationally prominent: 17311 ranks #7 of 2969 providers (100th percentile; extreme outlier), 17312 ranks #13 of 2770 providers (100th percentile; extreme outlier), and 17313 ranks #18 of 2300 providers (99th percentile; extreme outlier). These rank/percentile positions indicate this NPI is a major national volume outlier for Mohs procedures rather than a modest regional contributor.

Other high‑volume items beyond Mohs reinforce broad procedural throughput and patient visits: 99213 accounts for $121.3K (5.9%) with 2K claims and ranks #872 of 457151 providers (100th percentile; extreme outlier), and 99204 generated $41.2K (2.0%) and ranks #855 of 227068 providers (100th percentile; extreme outlier). Strong volume in these E/M codes suggests substantial ambulatory clinic throughput in addition to surgical cases.

Several ancillary and pathology codes show integration of intraoperative pathology and lab services into the surgical workflow: 88331 produced $30K (1.5%) and ranks #62 of 4659 providers (99th percentile; notably above typical national volume), while 88342 produced $22K (1.1%) and ranks #1494 of 11370 providers (87th percentile; typical, unremarkable volume). The presence of 88331 at high percentile supports use of intraoperative pathology consults consistent with Mohs practice patterns.

A cluster of high‑percentile reconstruction and repair codes (for example, 15260 rank #10 of 1336 providers, 99th percentile; 13132 rank #50 of 3088 providers, 98th percentile; and 14060 rank #13 of 2135 providers, 99th percentile) indicates the provider not only performs Mohs excisions but also handles complex closures and grafts at volumes well above typical national peers. This combination increases average paid/claim (e.g., 15260 avg paid/claim $713, 14301 avg paid/claim $788) and is consistent with a high‑acuity procedural mix.

Tenure data show the NPI was enumerated on 2006-07-05 (~20 years ago), indicating a long‑standing practice presence. Combined with the $2.2M in Medicare receipts and the outsized national ranks on core procedure codes, the pattern is consistent with an established, referral‑driven Mohs/reconstruction practice rather than a newly entered or sporadically billing provider.
