    Key Findings

    WHITMAN-WALKER CLINIC, INC reports no Medicare billing on file and $23.3M in lifetime Medicaid revenue, making it effectively a Medicaid-focused provider in this dataset rather than a dual-payer operation. Analysts should treat Medicaid as the primary revenue stream when evaluating its payer exposure and contracting leverage.

    Revenue is highly concentrated: the top 3 Medicaid codes account for 97.9% of the provider's total Medicaid revenue. The single largest line item is T1015 ($17.3M; 74.1% of Medicaid revenue), followed by G0467 ($5.3M; 22.7%) and T2023 ($264.4K; 1.1%), indicating the clinic’s finances are driven overwhelmingly by a very small set of service codes.

    The code mix reflects an FQHC ambulatory primary-care and wraparound services model. High volumes and revenue for T1015 (Clinic visit/encounter, all-inclusive) and G0467 (FQHC visit, established patient) indicate day-to-day operations center on bundled clinic encounters, while the presence of codes such as T2023, T2022, 90853, and dental codes (D1110, D0120, D0220) shows additional case management, behavioral health group services, and dental care are offered alongside core primary care.

    T1015 is a statewide outlier in volume: it ranks #4 of 97 providers in-state (97th percentile) and is described as notably above typical state volume for this code, signaling the clinic is one of the largest billers of the all-inclusive clinic visit in DC. G0467 also ranks very highly (#2 of 31 providers; 97th percentile) but is annotated as typical/unremarkable in volume for that peer set, suggesting the clinic is among the top billers for standard FQHC established-patient visits even if that pattern is common across large FQHCs.

    Beyond the top two codes, complementary services generate comparatively small revenue but demonstrate service breadth. Case management codes such as T2023 ($264.4K; 1.1%) and T2022 ($199.8K; 0.9%) are present at modest, typical volumes (ranking in middle percentiles), and behavioral health group psychotherapy 90853 ($87.9K; 0.4%) and dental preventive code D1110 ($48.8K; 0.2%) show additional but limited Medicaid revenue streams.

    The provider’s long tenure (NPI enumerated 2005-08-19, ~21 years ago) combined with an FQHC taxonomy supports the interpretation of an established community clinic with sustained Medicaid activity; this longevity may underpin the high volumes observed for core FQHC visit codes. Analysts assessing network stability or service continuity can consider this long-standing Medicaid presence as evidence of persistent operating capacity.

    From a competitive and contracting perspective, dependence on a small set of high-revenue FQHC visit codes concentrates both negotiating leverage and revenue risk. Because T1015 and G0467 together dominate Medicaid revenue (see their individual shares above) payers and partners should expect most visit-based payments and utilization to flow through those bundles, making rate or policy changes for those codes disproportionately impactful on the clinic’s revenue.

    Statistical characterizations in the data are mixed and should be interpreted contextually: T1015 is explicitly flagged as notably above typical state volume (an elevated outlier in utilization), while G0467—though ranked similarly high—carries a label of typical/unremarkable volume for its peer group. This suggests WHITMAN-WALKER is an unusually large user of the all-inclusive clinic encounter in-state, while its pattern for standard FQHC established-patient visits aligns with other large FQHCs in the state.
