    Key Findings

    Practice profile and service mix: As a Hematology & Oncology Physician, the provider’s claims are dominated by high-cost oncology injectables and associated infusion/E/M services, with J9271 (pembrolizumab) and J9144 (daratumumab) the top drug codes and multiple chemotherapy administration codes (96413, 96365, 96401, 96417) present on the top-25 list. The presence of supportive-care agents (J0897 denosumab, J0881 darbepoetin alfa, J1449 eflapegrastim, J1569 immune globulin) and tumor marker/lab testing (86300, 80053, 85025, 82378) further indicates a full-spectrum oncology infusion practice treating both solid tumor immunotherapy and hematologic indications. This mix is consistent with a clinic that provides on-site drug administration plus routine oncology monitoring.

    Revenue concentration: Revenue is highly concentrated in a small set of Medicare codes — the precomputed top 3 Medicare codes account for 67.8% of this provider’s total Medicare revenue. Individually, J9271 accounts for $722.5K (43.8% of Medicare revenue), J9144 accounts for $294.1K (17.8%), and 99214 accounts for $101.7K (6.2%), showing the business is heavily dependent on a few high-revenue items. This concentration implies that changes in reimbursement or utilization for those specific drugs or services would materially affect overall revenue.

    Payer mix and single-payor exposure: Lifetime Medicare revenue is $1.7M while Medicaid shows none on file, so this provider is effectively single-payer (Medicare) in the claims data available. That lack of Medicaid billing indicates limited state-program exposure and a dependence on Medicare policy and beneficiary volume for revenue stability, which is an operational and reimbursement concentration risk to monitor.

    Competitive standing on top drug codes: For high-revenue oncology injectables the provider’s national ranks are in the middle of the peer distribution: J9271 ranks #566 of 1841 providers nationally (69th percentile; labeled typical, unremarkable volume) and J9144 ranks #320 of 615 providers nationally (46th percentile; labeled typical, unremarkable volume). These positions suggest the provider is a modest, regionally competitive participant for these expensive immunotherapy/oncology drugs rather than a national leader.

    Exceptional E/M volume relative to peers: The office E/M code 99214 is an outlier for this provider — it generates $101.7K (6.2% of Medicare revenue) and the provider ranks #7199 of 479517 providers nationally (98th percentile; labeled extreme outlier, far above typical national volume for this code). That extreme percentile for 99214 indicates much higher-than-typical billing of moderate-complexity established-patient visits compared with national peers and may reflect either a high panel size, frequent follow-up cadence, or coding practice that yields elevated 99214 volume.

    Ancillary and lab utilization: Multiple lab and monitoring codes appear in high national percentiles, including 86300 (rank #51 of 987, 95th percentile) and common panels CBC/CMP (85025 rank #1021 of 32833, 97th percentile; 80053 rank #826 of 26416, 97th percentile), each contributing nontrivial revenue. These placements indicate above-typical ordering of tumor markers and routine labs relative to peers, consistent with active management and monitoring of oncology patients and likely generating recurring ancillary revenue streams.

    Operational tenure: The provider’s NPI was enumerated on 2006-01-17 (~20 years ago), indicating long-standing presence in the Medicare system. That tenure supports interpretation of patterns as established practice behavior rather than short-term spikes and suggests historical continuity in patient panel and service mix.

    Implications for payers and downstream review: Given the dominant role of a few high-cost drug codes (top 3 = 67.8% of Medicare revenue) and the absence of Medicaid billing, payers should prioritize review of utilization and contract terms for J9271 and J9144 and monitor the unusually high 99214 volume for appropriateness and care pattern context. The combination of typical peer standing on expensive injectables but extreme E/M volume and high lab utilization suggests focused operational levers (visit frequency, lab ordering, drug mix) where care management or network strategies could meaningfully influence spend.
