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

Why is the Medicaid comparison limited to Alabama 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. Alabama (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 is a Dermatology Physician with a long Medicare presence — NPI enumerated 2008-07-31 (~18 years ago) — and has generated $1.6M in total Medicare revenue while reporting no Medicaid billing on file, making Medicare effectively the sole public payer for this profile. The lack of any Medicaid activity means analyses of state-level Medicaid competition or payer-mix shifts are not supported by the data.

Revenue is highly concentrated in a small set of codes: the precomputed top 3 Medicare codes by revenue account for 87.4% of this provider's total Medicare revenue, indicating the practice’s financial profile is driven by a narrow set of high-revenue items rather than a broad mix of office visits and minor procedures. This concentration suggests business risk if reimbursement or utilization patterns change for those specific items.

Q4188 is the single dominant revenue driver, generating $1.1M or 66.0% of this provider's Medicare revenue. Nationally this provider ranks #10 of 47 for Q4188 (80th percentile), which places them toward the upper end of a relatively small national cohort that bills this product, consistent with a focused use of amniotic membrane/skin substitute products in their practice.

Q4194 is the second-largest Medicare revenue source at $207.7K (13.0% of Medicare revenue) but ranks #53 of 69 nationally (24th percentile), indicating the provider bills Novachor at a meaningful dollar level to their own revenue mix while remaining a modest user compared with the broader national set of billers for that product. This contrast with Q4188 shows the practice relies heavily on one amniotic product while using a second similar product at far lower relative market share.

17311 (Mohs surgery) contributes $134.7K (8.4% of Medicare revenue) and the provider ranks #1216 of 2969 nationally (59th percentile), suggesting the practice performs Mohs at roughly mid-level volume among dermatologic surgeons. The presence of Mohs codes alongside large amniotic/skin-substitute billing implies a mixed service line where complex surgical oncology care is present but not the dominant revenue source.

Beyond the top three, several wound/skin‑substitute and repair codes appear in the top-25, for example 15275 ($19.9K, ranks #66 of 888, 92th percentile) and J7308 ($10.4K, ranks #687 of 1726, 59th percentile), which supports the interpretation that the practice’s business model emphasizes advanced graft/substitute products and procedural reconstruction rather than high-volume evaluation-and-management visits. Office visit codes 99213 and 99212 are present but together account for a small share of revenue, underlining a procedural, product-driven revenue mix.

Competitive standing is mixed: for the primary revenue code Q4188 the provider is relatively prominent within a small national group (80th percentile), but for other high-dollar items like Q4194 the provider is a modest participant (24th percentile) and for Mohs (17311) they sit near the national median (59th percentile). This profile indicates regional/niche strength in amniotic product use paired with typical procedural volumes for surgical dermatology.

From a payer and operational perspective, the combination of very high reliance on Q4188 (66.0% of Medicare revenue) and no Medicaid activity means the provider’s Medicare performance is the critical factor for payer-lead analyses. Analysts should treat future changes to coverage or pricing for amniotic membrane products as high-impact to this provider’s revenue and prioritize audit of utilization trends for Q4188, Q4194 and Mohs-related codes when modeling financial exposure or competitive shifts.
