    Key Findings

    This provider’s billing is effectively single‑payer: lifetime Medicare revenue is $951.3K while Medicaid shows none (no Medicaid billing on file), indicating the practice derives virtually all public‑payer volume from Medicare and has no recorded Medicaid activity. That concentration implies payer mix and network considerations should be evaluated primarily against Medicare reimbursement and utilization patterns rather than dual‑payer strategies.

    Revenue concentration is high among biologic drug administration codes: the precomputed top‑3 Medicare codes account for 53.2% of total Medicare revenue, with J0717 generating $199.2K (21.4%), J0129 generating $168.3K (18.1%), and J1745 generating $127.9K (13.7%). This concentration shows the practice’s revenue is driven primarily by high‑cost injectable biologics rather than by a broad portfolio of office visit fees.

    Business/service‑line signals are consistent with an infusion/biologics‑focused rheumatology practice: dominant codes are J0717, J0129, and J1745 (certolizumab, abatacept, infliximab), and the presence of infusion administration codes such as 96413, 96401, 96415, and 96365 indicates in‑office infusion/administration capacity. Combined with frequent lab codes (e.g., 82565, 84450, 84460) and DXA imaging (77080, 77089), the mix suggests ongoing monitoring and in‑clinic procedures typical for long‑term biologic management in rheumatology.

    Competitive standing on drug codes is mixed: J0717 ranks #406 of 848 providers nationally (52th percentile) and is described as typical, unremarkable volume for this code, J0129 ranks #899 of 1221 (26th percentile) and is also typical, unremarkable volume, while J1745 ranks #380 of 1352 (72th percentile) with typical, unremarkable volume. In plain terms, this provider is not a dominant national outlier for these biologics but does sit at mid‑range to upper‑mid range on some drug lines, reflecting a modest national footprint for individually reported drug codes.

    Clinical throughput for office visits and basic procedures is notable: 99213 appears at 781 claims and $45.3K revenue and ranks #11287 of 457151 providers nationally (98th percentile), explicitly labeled as notably above typical national volume for this code. High percentile rankings for routine specimen collection (36415, 94th percentile) and several common lab tests (e.g., 82565 at the 96th percentile) further indicate above‑typical throughput of outpatient visits and ancillary services supporting ongoing chronic care.

    Operational risk and sensitivity: because over half of Medicare revenue (53.2%) is concentrated in three biologic drug codes, the practice’s revenue profile is sensitive to changes in drug reimbursement, utilization patterns, or site‑of‑care payment policies for these specific agents. Payers and financial analysts should view this as a strategic dependency on billed biologics and on in‑office administration capacity.

    Tenure and market presence: the NPI was enumerated on 2006-08-20 (~20 years ago), indicating long‑standing enrollment and potential continuity of care in the market. This tenure supports the observed steady volume of chronic care services and recurring biologic administration reflected in the claims mix.

    Practice-level implications for network and contract strategy: given the lack of Medicaid billing and a Medicare‑centric revenue base of $951.3K, contract negotiations and utilization management should be focused on Medicare fee schedules, drug reimbursement policy, and infusion service rates rather than Medicaid program terms. Payers considering network alignment should also account for the provider’s above‑typical office visit and lab throughput when modeling utilization and downstream monitoring needs.
