    Key Findings

    Practice profile and service lines: The provider's Medicare billing is dominated by office-based evaluation and management, with 99213 and 99214 together making up the bulk of visit activity and revenue. The presence of vaccine administration codes (G0008, 90688), basic diagnostic imaging (71046), EKG codes (93010/93005), point-of-care lab tests (87811, 81002), and multiple infusion/injection codes (96365, 96361, J7120, J0696, J7050) indicates a family-medicine outpatient practice that provides routine chronic care, preventive services, in-office vaccinations, and occasional parenteral therapies on-site.

    Revenue concentration: This provider’s total Medicare revenue is $46K and its top three Medicare codes (99213, 99214, G0008) account for 85.9% of that Medicare revenue. Individually, 99213 represents 53.3% and 99214 represents 28.3% of total Medicare revenue, showing tight concentration in low- to moderate-complexity office visits.

    Payer mix: The provider is effectively single-payer in the available data with $46K in Medicare revenue and no Medicaid billing on file. This absence of Medicaid activity means analyses of Medicaid exposure, network participation, or state-level Medicaid share are not applicable for this NPI.

    Competitive standing on major codes: 99213 ranks #34091 of 457151 providers nationally (93th percentile; typical, unremarkable volume) and 99214 ranks #180509 of 479517 providers nationally (62th percentile; typical, unremarkable volume). These ranks indicate the provider has measurable visit volume for common office E/M codes but is described in the source as operating at a typical or unremarkable level nationally rather than as a dominant national outlier.

    Billing pattern nuance — infusions and drug claims: The record lists multiple J-codes and infusion-related entries (for example, J0696 with 161 claims and $0 revenue, and J7050 with 38 claims and $0 revenue) alongside billed IV administration codes such as 96365 (31 claims, $1.6K revenue). The occurrence of claims with $0 paid suggests either non-covered supply billing, bundled payment handling, or carrier-level nonpayment for those specific drug items on Medicare claims rather than absence of in-office administration.

    Clinical complexity and visit mix: The distribution heavily favors lower- to moderate-complexity office visits (99213 and 99214 together represent the majority of revenue), implying routine chronic-disease management and primary-care ambulatory encounters. Preventive and episodic services are supported by influenza vaccine codes (G0008, 90688) and point-of-care testing (87811), consistent with a full-scope family medicine outpatient panel.

    Tenure and operational stability: The provider’s NPI was enumerated 2007-02-26 (~19 years ago), indicating long-standing enrollment in Medicare which supports interpretation of billing patterns as established rather than newly emergent. Longevity combined with concentrated E/M billing suggests a stable outpatient practice with an established Medicare patient base.

    Statistical outliers and peer comparisons: Across the listed Medicare codes, most entries are labeled in the source as "typical, unremarkable volume" (for example, G0008 at 58th percentile and 90688 at 82th percentile both noted as typical), and no code in the supplied list is identified as an extreme outlier. Overall, national percentiles vary, but the dataset characterizes the provider’s activity as broadly typical among peers rather than unusually high or low for the majority of reported codes.
