    Key Findings

    This provider is effectively single-payer focused: lifetime Medicare revenue totals $118.2K while there is no Medicaid billing on file, indicating the practice's public-payor activity is concentrated entirely in Medicare rather than split across Medicare and Medicaid. Analysts should treat Medicaid as not applicable for competitive or volume comparisons for this NPI.

    Revenue concentration is high: the precomputed top three Medicare codes account for 84.3% of this provider's total Medicare revenue, signaling dependence on a small set of office E/M services for the bulk of income. This concentration suggests visits rather than procedures or ancillary services drive the practice's Medicare economics.

    Service mix and business model inference: the dominant codes are E/M office visit codes 99214 (50.3% of Medicare revenue), 99213 (18.8%), and 99215 (15.2%), which together reflect a family medicine outpatient practice built on longitudinal established-patient visits across low-to-high complexity encounters. The presence of vaccine administration codes (G0008, 90688, 90732) and basic point-of-care testing (87811, 87804) supports a primary care model that combines routine preventive care and in-office testing.

    Competitive standing on high-volume E/M: 99214 revenue ranks #16428 of 479517 providers nationally and is described as notably above typical national volume (97th percentile), indicating this provider is an unusually heavy biller of moderate-complexity established-patient visits compared with peers. 99213 and 99215 are at the 92nd and 85th percentiles respectively, which positions the provider above average on those E/M services as well but less extremely than 99214.

    Statistical outlier signals beyond E/M: the vaccine product 90688 is flagged as an extreme outlier (rank #50 of 3096, 98th percentile) and produces $3.8K (3.2% of Medicare revenue). This suggests unusually high use or reporting of that specific influenza vaccine product relative to national peers and may reflect local seasonal vaccination volume or procurement/billing patterns worth investigating for operational planning or supply forecasting.

    Operational detail: the practice also bills basic in-office infusions and injections (96365, 96372) and common diagnostic services (93010/93005 ECG work, 71046 chest x-ray), but these contribute small shares individually (each ≤1.6% of Medicare revenue) and rank in middling-to-low percentiles nationally. These findings indicate ancillary services exist but are not a major revenue driver relative to E/M visits.

    Tenure and standing: the NPI was enumerated on 2007-01-09 (~19 years ago), providing long-term presence in the Medicare program which supports the observed stable E/M billing profile and above-average ranking for core office visit codes. This longevity strengthens the inference that current billing patterns reflect an established ambulatory family medicine practice rather than a new or transient provider.
