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

Why is the Medicaid comparison limited to New Mexico 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. New Mexico (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

MICHAEL CHANG is an established dermatology physician enumerated on 2011-04-01 (~15 years ago) and reports $465.4K in lifetime Medicare revenue with no Medicaid billing on file (none). The absence of Medicaid claims makes this effectively a single-payer (Medicare) billing footprint in the available data, which has implications for network participation and underserved-patient exposure analysis.

Revenue is heavily concentrated in a small set of procedural codes: the precomputed top 3 Medicare codes account for 57.7% of this provider's total Medicare revenue. The three revenue drivers are 17311 ($162.2K, 35.8% of Medicare revenue), 99213 ($54.9K, 12.1%), and 17312 ($44.3K, 9.8%), indicating a narrow set of services that produce most of the billed Medicare dollars.

The code mix points to a surgical dermatology practice with a strong Mohs surgery and reconstruction focus: 17311, 17312, and 17313 are the lead codes for staged excisional (Mohs) procedures, while intermediate and complex repair codes such as 12032 ($18.5K), 12052 ($10.2K), 13152 ($5.8K) and graft/repair codes 15260 ($13.1K) and 14060 ($12.3K) demonstrate an active reconstructive workload following tumor extirpation. This combination of Mohs plus adjacent-site repairs and grafting is consistent with a practice organized around surgical skin cancer care rather than purely medical dermatology.

Clinical throughput is notable for evaluation-and-management volume: 99213 appears with 998 claims, $55 avg paid/claim and $54.9K revenue and is labeled an "extreme outlier, far above typical national volume" (99th percentile). That unusually high established-patient visit volume suggests substantial clinic-level demand and follow-up capacity that likely supports the procedural/Mohs service line rather than a low-visit procedural boutique model.

Competitive standing for the primary Mohs procedure is modest nationally: 17311 generates the single largest revenue line ($162.2K) but ranks #919 of 2969 providers nationally (69th percentile) and is characterized as a "typical, unremarkable volume for this code." Likewise 17312 ranks at the 54th percentile (#1260 of 2770), so while Mohs is the dominant revenue generator here, the provider is not a dominant national outlier for those Mohs codes.

Certain reconstructive and adjunct procedure codes show relatively higher percentile standing within their code cohorts, indicating a measurable procedural intensity beyond basic excisions. For example, 12032 is $18.5K and ranks #453 of 6420 providers (93th percentile) and 17000 is $24.2K and ranks #1833 of 21879 providers (92th percentile); these placements suggest above-typical volume for intermediate repairs and lesion destruction, supporting the characterization of a surgery-focused practice with significant post-excision reconstruction.

Intraoperative pathology and related services are present and contribute to the surgical workflow: 88331 appears with 90 claims, $75 avg paid/claim and $6.8K revenue and ranks #586 of 4659 providers (87th percentile). The presence and percentile of 88331 aligns with an in-office or closely integrated pathology service commonly used to support Mohs procedures and real-time surgical decision-making.

From a payer-mix and scale perspective, the practice is modest in Medicare-dollar terms ($465.4K total Medicare revenue) and has no recorded Medicaid activity (none). That combination—concentrated Medicare revenue driven largely by Mohs and E/M codes and no Medicaid billing—signals a specialized, Medicare-focused surgical dermatology operation with limited or no engagement in the Medicaid patient population in the dataset.
