    Key Findings

    This provider’s Medicare revenue totals $4.2M while there is no Medicaid billing on file, so the practice is effectively single-payer in the available data and has no documented Medicaid footprint to diversify payer mix. The absence of Medicaid billing may limit visibility into low-income patient volumes and suggests analysts should treat the profile as Medicare-centric when assessing market access or network participation in-state.

    Revenue is highly concentrated in a small set of injectable biologics: the precomputed top 3 codes account for 59.5% of this provider's total Medicare revenue. Specifically, J0717 accounts for $1.1M (24.9%), J0129 for $806K (19.0%), and J0897 for $657.7K (15.5%), indicating dependency on in-office administration of high-cost J‑code drugs.

    The code mix points to an infusion/injection-focused rheumatology operation: large revenues tied to J0717, J0129, J0897, J3262 and J1745 are consistent with in-office administration of biologic therapies and disease-modifying injections rather than a purely ambulatory visit model. High-volume billing on chemotherapy/infusion administration codes such as 96401 ($137.1K) and add-on infusion code 96415 ($6.6K) further supports that the practice runs infusion services and performs scheduled parenteral drug administrations.

    Several individual codes show national-level dominance or markedly higher-than-typical volume: J0717 ranks #11 of 848 (99th percentile; extreme outlier) and J0897 ranks #57 of 10057 (99th percentile; extreme outlier), signaling unusually high national volume for these specific products. J0129 also performs notably above typical national volume, ranking #81 of 1221 (93th percentile), so the practice is a major national outlier for multiple biologic injections used in rheumatology care.

    Beyond drug administration, the practice bills substantial office E/M and procedure volume that is also unusual relative to peers. 99214 appears as an extreme outlier ($205.2K; ranks #1284 of 479517, 100th percentile) and 20610 joint injection work shows extreme outlier volume ($53.5K; ranks #241 of 39752, 99th percentile), indicating the provider combines high visit volume and procedural joint care with infusion services.

    There are additional high-percentile signals in chemotherapy/infusion and related codes: 96401 ($137.1K) ranks #7 of 3868 (100th percentile; extreme outlier) and 96413 ($89.9K) ranks #184 of 7514 (98th percentile; notably above typical national volume). These rankings reinforce that the practice operates a high-throughput administration suite for injectable or infused agents, which has important operational, staffing, and revenue-cycle implications.

    Tenure data show the NPI was enumerated on 2006-12-13 (~20 years ago), indicating long-standing registration and potentially established referral relationships and operational infrastructure for the services observed. This longevity, coupled with the concentration in infusion and injection codes, suggests a mature rheumatology practice that has developed a specific service line around biologic administration.

    Concentration risk is material: with 59.5% of Medicare revenue coming from three J‑codes and total Medicare revenue of $4.2M, shifts in drug utilization, payer coverage, or site-of-care reimbursement for a small number of products could meaningfully affect overall revenue. Analysts should flag exposure to changes in biologic administration patterns and consider monitoring utilization trends for J0717, J0129, and J0897 closely.
