    Key Findings

    This provider has no Medicare billing on file and only $5.2K in lifetime Medicaid revenue, meaning its documented public-payer footprint is effectively single-payer and very small in absolute terms. The absence of Medicare activity prevents any national Medicare competitiveness analysis for this NPI.

    Medicaid revenue is highly concentrated: the precomputed top-3 Medicaid codes account for 100.0% of this provider's total Medicaid revenue, with the two reported codes alone making up that full share. Specifically, 99204 generates $3.1K (59.1% of Medicaid revenue) and 99213 generates $2.1K (40.9% of Medicaid revenue), indicating virtually all Medicaid receipts come from standard office evaluation-and-management visits.

    Operationally, the provider is listed under the Surgery Physician taxonomy but the Medicaid code mix is dominated by office/outpatient evaluation and management codes (99204 and 99213). This pattern suggests the NPI’s Medicaid activity centers on E&M encounters—new and established patient visits—rather than surgical procedure billing to Medicaid.

    Claim-level detail shows modest case volume: 99204 appears on 27 claims with a $114 avg paid/claim totaling $3.1K, while 99213 appears on 38 claims with a $56 avg paid/claim totaling $2.1K. These per-claim averages and low claim counts underline the small scale of Medicaid operations under this NPI.

    Competitive standing within the state is modest for both top codes: 99204 ranks #14 of 20 providers in-state (32th percentile; typical, unremarkable volume), and 99213 ranks #43 of 48 providers in-state (11th percentile; typical, unremarkable volume). Neither code shows a dominant or above-typical presence statewide, consistent with the low total Medicaid revenue.

    The NPI was enumerated on 2017-06-15 (~9 years ago), so the provider has been active for several years despite limited public-payer billing. The combination of multi-year enumeration and minimal Medicaid revenue suggests the practice either has a small Medicaid panel, focuses on non-public payers, or bills other NPIs for higher-acuity procedure work.

    From a risk/variance perspective, neither reported Medicaid code is flagged as an outlier in the supplied labels—both are described as "typical, unremarkable volume for this code." Given that characterization and the small absolute revenue ($5.2K), there is no statistical indication in the Medicaid data of unusually high or anomalous billing behavior for the codes on file.
