    Key Findings

    This provider is effectively a Medicare-only billing entity: lifetime Medicare revenue is $6.5M while Medicaid revenue is listed as none, so the practice operates as a single-payer (Medicare) commercial footprint in the available data. The absence of any Medicaid billing on file indicates Medicaid is not a material revenue source or payer relationship for this provider.

    Revenue is highly concentrated in a small set of diagnostic and procedure codes: the precomputed top 3 Medicare codes account for 57.7% of total Medicare revenue, with Q4234 alone contributing $2.2M (35.5% of Medicare revenue). That concentration signals that a handful of services—particularly the top add-on and pathology codes—drive the majority of collected Medicare dollars.

    The code mix points to a pathology- and procedure-driven operation rather than a general outpatient primary-care practice. High-revenue pathology and immunohistochemistry codes such as 88305, 88312, 88341, 88360, and 88344 dominate the list, indicating substantial surgical pathology specimen processing, special stains, and antibody staining work consistent with dermatopathology or biopsy-centric dermatology services.

    Several pathology-related codes show extreme deviation from typical national volumes: 88312 (7.2K claims, $758.1K revenue) is labeled an "extreme outlier, far above typical national volume" and ranks #19 of 6966 providers, while 88341, 88360, 88313, and 88344 are also 100th-percentile codes described as extreme outliers or far above typical national volume. These rankings indicate this provider is a major national outlier in laboratory/staining services relative to peers, and the practice likely processes far more pathology workload than typical dermatology clinicians.

    Not all high-revenue codes indicate extraordinary market position: Q4234 (3.4K claims, $2.2M revenue) is the single largest revenue contributor but is described as "typical, unremarkable volume for this code" and ranks #2 of 23 providers nationally (95th percentile). This suggests that while Q4234 drives revenue by dollar amount, the underlying utilization pattern for that specific add-on is within expected bounds for the defined peer group, and the provider’s outsized Medicare revenue owes more to volume across multiple pathology codes than to a single anomalous utilization.

    Clinical evaluation-and-management (E/M) codes appear modest relative to the pathology mix: 99214 and 99215 are reported at the 91st percentile and labeled typical/unremarkable, together contributing small shares of revenue (e.g., 99214 $57.9K, 99215 $28.2K). This contrast reinforces that direct patient visit revenue is secondary to pathology and procedure-driven revenue streams in this provider’s Medicare profile.

    The provider’s national competitive standing is mixed but skewed toward dominance in laboratory services: several procedure codes rank at or near the top nationally (for example, multiple destruction/excision codes are rank #1 for small peer counts and many pathology codes are in the 99–100th percentiles). Collectively this pattern portrays a practice that is a major, even dominant, participant in specific pathology/immunostain services at the national level while being a more typical participant for some procedural add-ons and office visits.

    The provider has a long active enrollment history that supports stable operations: NPI was enumerated 2008-06-27 (~18 years ago). That tenure, combined with consistent high-volume pathology coding, suggests an established service model and sustained specialization in biopsy/pathology-related dermatology care over many years.
