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

Why is the Medicaid comparison limited to New Hampshire 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 Hampshire (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 Medicare business is modest in absolute scale but concentrated: total Medicare revenue is $464.1K and the top 3 Medicare codes by revenue together account for 43.6% of that total. The revenue mix is dominated by office E/M and skin procedure codes, indicating a focused outpatient dermatology practice rather than a broad multispecialty operation.

99214 is the single largest revenue driver, accounting for 24.4% of Medicare revenue and generating $107.6K; the provider ranks #6780 of 479517 nationally for 99214 and is labeled an "extreme outlier," which signals a very high national volume of higher-complexity established patient visits relative to peers. High 99214 volume alongside substantial procedural billing suggests the practice combines medically-complex office management with procedure throughput.

Procedural lesion management is a second major service line: 17004 contributes 10.8% of Medicare revenue ($47.5K) and 11102 contributes 8.5% ($37.3K). Both codes rank in the 97th percentile nationally (17004 #297 of 9638, 11102 #651 of 18797) and are described as "notably above typical" volumes, which positions the provider as a high-volume local/source for premalignant lesion destruction and tangential lesion biopsies.

The provider reports unusually high volume on several other dermatologic procedure codes: 11300 is an "extreme outlier" (rank #20 of 1624) and 17003 shows very large claim count (3.4K claims) while ranking 96th percentile (#868 of 19643). These flags point to a practice workflow that processes large numbers of lesion destructions and shave biopsies, consistent with a procedure-oriented dermatology clinic.

Revenue is not diversified across payers: there is no Medicaid billing on file (none), so this provider is effectively single-payer from a claims perspective with Medicare representing the entirety of recorded public-payer activity. That concentration means competitive or operational shifts in Medicare reimbursement or referral patterns could materially affect practice revenue.

The mix of codes for repairs and excisions (for example, 13121 $22.6K, 13132 $16.3K, 13101 $14K, and excision codes 11602/11603) indicates the practice performs a meaningful volume of surgical repairs and cancer excisions in addition to biopsies and lesion destruction. These mid-range surgical revenue lines, combined with high-volume minor procedure codes, suggest staffing and facility resources oriented to in-office dermatologic surgery.

Competitive standing is uneven across services: for high-level office visits and common lesion procedures the provider ranks well above peers nationally (e.g., 99214 and 11300 are 99th percentile extreme outliers; 17004 and 11102 are 97th percentile), while several repair and excision codes sit at more typical percentiles (for example, 13121 at the 75th percentile). This pattern implies regional dominance in routine dermatologic procedures and established-visit management, with more typical participation in complex repairs.

NPI tenure shows the provider has been enumerated since 2017-05-01 (~9 years ago), indicating a relatively established presence in the market long enough to build the high procedural volumes observed. The combination of near-decade tenure, concentrated Medicare revenue of $464.1K, and multiple high-percentile codes supports a profile of a stable, procedure-focused dermatology practice with limited or no Medicaid engagement.
