    Key Findings

    This provider is effectively single‑payer: Total Medicare revenue is $3.9M while Total Medicaid revenue is none (no Medicaid billing on file), so Medicare entirely dominates reported public‑program activity. Analyses of utilization and financial exposure should therefore focus on Medicare fee‑for‑service patterns rather than a dual‑payer mix.

    Revenue is highly concentrated in a small set of immunotherapy and oncology drug codes — the precomputed top 3 Medicare codes account for 82.5% of this provider's total Medicare revenue. In particular, J9271 accounts for $2.4M (62.9% of Medicare revenue) and J9299 contributes $628.3K (16.7%); this concentration implies that a few high‑cost drug lines drive the majority of income.

    The code mix indicates an infusion‑centric oncology practice: J9271 (pembrolizumab) and J9299 (nivolumab) are the primary revenue drivers, supported by chemotherapy administration codes such as 96413 ($75.3K) and add‑on/infusion codes like 96417 ($7.3K) and 96375 ($12.2K). Additional supportive biologics and growth‑factor billing (J2506 pegfilgrastim $71.6K; Q5122 biosimilar $45.8K) further support an active chemotherapy/immunotherapy service line with in‑office infusion capability.

    Competitive standing is uneven across products: for J9271 the provider ranks #10 of 1841 providers nationally (100th percentile; extreme outlier, far above typical national volume for this code), marking them as a national outlier and a major deliverer of pembrolizumab. By contrast, J9299 ranks #88 of 505 providers nationally (83th percentile; typical, unremarkable volume for this code), indicating more ordinary participation in nivolumab relative to peers.

    Several additional oncology codes show unusually high relative volume, reinforcing specialization: 99214 (1.1K claims, $107.6K) ranks #8079 of 479517 providers nationally (98th percentile; extreme outlier, far above typical national volume for this code), J9217 (578 claims, $77.5K) ranks #43 of 3683 (99th percentile; extreme outlier, far above typical national volume for this code), and J9171 (11.1K claims, $11.1K) ranks #5 of 207 providers nationally (98th percentile; extreme outlier, far above typical national volume for this code). These ranks point to both high clinical throughput and deep engagement with multiple oncology therapeutics compared with national peers.

    The provider maintains a steady stream of evaluation‑and‑management visits consistent with active longitudinal oncology care: 99214 (1.1K claims, $107.6K), 99213 (690 claims, $44.9K), and 99215 (263 claims, $35K) all appear in the top codes list and hold high percentile ranks. High E/M volumes alongside large injectable volumes suggest the practice manages follow‑up, toxicity management, and treatment planning in‑clinic rather than exclusively referring infusions elsewhere.

    This NPI has long tenure in the billing file: NPI enumerated (registered) 2006-07-07 (~20 years ago), indicating an established practice presence in Hampton, VA. Longevity paired with the current code mix may reflect sustained oncology service delivery and an embedded referral base.

    Because a substantial share of Medicare dollars here is tied to a few high‑cost immunotherapies, the practice faces concentration risk: changes in utilization patterns, clinical guidelines, or reimbursement for J9271 and J9299 could materially affect revenue. Operationally, this profile favors monitoring drug‑specific utilization and payer edits, and evaluating whether infusion capacity, buy‑and‑bill exposure, or contracting leverage is aligned with this narrow revenue base.
