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

Why is the Medicaid comparison limited to South Dakota 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 Dakota (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 is effectively a Medicare-only biller in the dataset: total Medicare revenue is $619.3K and there is no Medicaid billing on file. The top 3 Medicare codes by revenue account for 58.5% of the provider’s Medicare revenue, indicating a concentrated Medicare practice rather than a balanced dual‑payer mix.

The revenue mix and code descriptions point to a surgical dermatology practice focused on skin cancer removal and complex reconstruction: the highest-revenue codes are 17311 and 17312 (Mohs surgery procedures) and 14060 (adjacent tissue transfer for defects 10 cm2 or less). These three codes together — 17311 (25.0%), 17312 (19.6%), and 14060 (13.8%) — drive the majority of procedural revenue, consistent with an operative, procedure-centered workflow rather than a predominantly office-based medical dermatology service.

Revenue concentration is high around a few procedural codes: 17311 contributes 25.0%, 17312 contributes 19.6%, and 14060 contributes 13.8% of the provider’s Medicare revenue, and those three codes together make up 58.5% of total Medicare revenue. For payers evaluating network impact or utilization risk, this profile signals dependence on a small set of high-value surgical services.

Competitive standing varies by procedure. The provider’s volume for 14060 is an outlier nationally (rank #27 of 2135, 99th percentile; labeled “extreme outlier, far above typical national volume”), indicating an unusually high reconstructive caseload for that code; by contrast, 17312 ranks #291 of 2770 (90th percentile) and 17311 ranks #723 of 2969 (76th percentile), both described as typical or unremarkable national volumes, which suggests strong relative emphasis on reconstruction compared with average Mohs volumes.

The practice is procedure-heavy rather than E/M-driven: 99213 appears at $23K (3.8% of Medicare revenue) with 360 claims, and other E/M codes such as 99203 ($8.5K, 1.4%) and 99214 ($2.1K, 0.3%) are smaller contributors. This pattern — substantial revenue tied to surgical CPTs and relatively modest E/M revenue — is consistent with a referral-oriented surgical dermatology model where operating-room or procedure revenue outweighs routine office visit revenue.

Pathology and lab services are present but not dominant: 88305 shows 657 claims and $17.7K (2.9% of Medicare revenue) and 88304 shows 167 claims and $2.7K (0.4%). These typical to modest pathology volumes (88305 rank #5923 of 14580, 59th percentile; 88304 rank #822 of 8796, 91st percentile) are consistent with regular specimen submissions from surgical cases but do not indicate an in-house pathology service generating major revenue.

The provider has a long Medicare tenure: the NPI was enumerated on 2007-08-14 (~19 years ago). This longevity combined with high-volume procedural coding for select reconstructive and Mohs-related CPTs suggests an established surgical dermatology practice with a stable referral and procedural base.

From a payer perspective, the absence of Medicaid billing means this provider presents limited Medicaid exposure and should be treated as effectively single-payer Medicare in historical claims analyses. That absence may reflect patient panel characteristics, local Medicaid participation choices, or billing arrangements, and it reduces the provider’s relevance to Medicaid network capacity assessments while elevating their importance for Medicare surgical service capacity planning.
