    Key Findings

    This provider is effectively a Medicare-focused practice: Total Medicare revenue is $2.4M and there is no Medicaid billing on file, so the provider operates as a single-payer (Medicare) participant in the available data. The absence of Medicaid claims means analyses of state-level Medicaid market share or dual-coverage patient flows are not possible from these files.

    Revenue is highly concentrated in a small set of immunotherapy and related injectables — the precomputed top 3 Medicare codes account for 63.7% of the provider's Medicare revenue, led by J9271 at 35.6%, J9299 at 18.7%, and J0897 at 9.5%. This concentration indicates most Medicare dollars flow through a few high-cost drug codes rather than diversified ancillary or procedural lines.

    The CPT/HCPCS mix signals an infusion-centered hematology/oncology practice: large volumes of J9271 (pembrolizumab), J9299 (nivolumab), and J0897 (denosumab) alongside chemotherapy administration codes such as 96413 and supportive agents like J2506 and J1568. These codes are consistent with ongoing systemic cancer therapy and in-office infusion operations rather than a primarily consultative or procedural surgical practice.

    Competitive standing by code shows a modest-to-strong national presence on key oncology drugs: J9271 ranks #295 of 1841 providers nationally (84th percentile; typical, unremarkable volume for this code), J9299 ranks #196 of 505 providers (61th percentile; typical, unremarkable volume for this code), and J0897 ranks #801 of 10057 providers (92th percentile; typical, unremarkable volume for this code). In other words, the provider is not among the very largest national centers for pembrolizumab or nivolumab but appears comparatively prominent for denosumab relative to the national provider pool.

    There are notable statistical outliers in utilization mix that deserve attention: 99214 is labeled an "extreme outlier, far above typical national volume for this code," with 1.1K claims and $91.1K revenue (3.9% of Medicare revenue), suggesting unusually high E/M visit billing for an oncology specialist. Conversely, J9311 shows an anomalous national rank (#5 of 5 providers, 0th percentile) in a very small comparator set; the dataset labels it "typical, unremarkable volume for this code," but the national sample size is minimal and should be interpreted cautiously.

    Claim volumes emphasize infusion throughput: the dataset reports 22.4K claims for J9271, 18.2K claims for J9299, and 12.2K claims for J0897, which together drive the majority of drug-related revenue. These claim counts, paired with additional chemotherapy administration entries (e.g., 96413 with 487 claims and G0498 with 65 claims), are consistent with a high-volume infusion workflow rather than a low-visit consult model.

    The provider has an established billing tenure: NPI enumerated 2014-05-13 (~12 years ago), indicating roughly a decade of presence in the Medicare billing data. That tenure, combined with $2.4M in Medicare revenue, supports the interpretation of a stable, operational oncology practice rather than a newly entered or transient billing entity.

    From a risk/opportunity perspective, the heavy reliance on a small set of high-cost oncology injectables creates revenue sensitivity to shifts in Medicare reimbursement policy, utilization management, or changes in clinical prescribing patterns for J9271, J9299, and J0897. Given there is no Medicaid billing on file, any payer diversification strategy (e.g., engaging Medicaid or additional commercial contracts) would materially change the payer mix and could mitigate concentration risk, but such opportunities are not visible in the current data.
