    Key Findings

    COOK COUNTY has no Medicare billing on file and reports $20.6M in lifetime Medicaid revenue, making its public reimbursement footprint effectively single‑payer (Medicaid) in the available data. This concentration means analyses of its financial profile and operational behavior should be interpreted through a Medicaid lens rather than a mixed Medicare/Medicaid comparison.

    Revenue is extremely concentrated: the platform’s precomputation shows the top three Medicaid codes account for 99.9% of this provider’s Medicaid revenue, and a single code, T1015, accounts for $20.5M (99.6% of Medicaid revenue). That heavy reliance on T1015 indicates the organization’s revenue is driven almost entirely by an all‑inclusive clinic visit/encounter payment stream rather than a diverse procedure mix.

    The code mix is consistent with a high‑volume ambulatory clinic or multi‑specialty center that bills encounter-based clinic visits: T1015 is dominant and a range of E&M codes (99214, 99213, 99215) appear frequently in the claims list. Despite high claim counts for some E&M codes, their dollar contribution is small relative to T1015 — for example, 99214 shows 14.2K claims for $28.4K revenue and 99213 shows 17.9K claims for $17.9K revenue — indicating Medicaid fee levels for those codes are low compared with the T1015 aggregate payment.

    Several E&M codes are statistical outliers by volume within Illinois: 99214 ranks #89 of 14,681 providers in‑state (99th percentile; extreme outlier), 99213 ranks #194 of 14,191 (99th percentile; notably above typical), and 99215 ranks #9 of 2,321 (100th percentile; extreme outlier). These percentile ranks suggest COOK COUNTY is an unusually large volume reporter of office/outpatient E&M visits compared with peers, even though those codes contribute only a tiny share of its Medicaid dollars.

    Immunizations and preventive visit codes are present at above‑typical volumes for certain vaccines: 90674 (cell‑based influenza vaccine) is 1.1K claims and ranks #8 of 171 providers in‑state (96th percentile; notably above typical), and 90732 (pneumococcal polysaccharide) ranks #13 of 46 (73rd percentile). While these services show elevated utilization relative to peers, they represent minimal revenue compared with T1015 and do not materially diversify the provider’s Medicaid revenue base.

    Competitive standing is mixed: on the primary revenue driver T1015 the provider ranks #107 of 846 in‑state (87th percentile; characterized in the source as typical, unremarkable volume), indicating a solid but not dominant statewide position for clinic‑encounter billing. At the same time, extremely high state percentiles on several E&M codes indicate COOK COUNTY is a major volume reporter for visit‑level services even though those services yield little Medicaid revenue for this provider.

    COOK COUNTY’s NPI was enumerated 2007-04-02 (~19 years ago), indicating an established operation. Coupled with a narrow revenue base (top three Medicaid codes = 99.9% of Medicaid revenue) and a dominant reliance on T1015, the provider appears to operate a long‑standing, high‑volume clinic model whose financial performance is highly sensitive to Medicaid encounter/clinic reimbursement policies and coding practices.
