    Key Findings

    COOK COUNTY is effectively a Medicaid-centered operation: there is no Medicare billing on file and lifetime Medicaid revenue is $85.9M, while Medicare revenue is listed as none. The provider’s NPI has been active since 2007-03-29 (~19 years), indicating long-standing presence in the market despite single-payer concentration.

    Revenue is extremely concentrated at the code level: the precomputed top three Medicaid codes account for 99.7% of this provider’s total Medicaid revenue, and a single code, T1015, represents $85.5M or 99.5% of Medicaid revenue. This degree of concentration means the provider’s topline is driven almost entirely by one bundled clinic/encounter code.

    T1015’s profile (255.1K claims, $335 avg paid/claim, $85.5M revenue) and its in-state rank (16 of 846, 98th percentile; notably above typical state volume) indicate COOK COUNTY operates a very high-volume clinic model that bills an all-inclusive clinic/encounter code. That mix is consistent with a multi-specialty ambulatory or safety-net clinic that centralizes many services under a bundled visit rather than a wide dispersion across discrete procedure codes.

    Although T1015 dominates revenue, the provider also reports very large claim volumes on standard E/M codes with low per-claim Medicaid payments: 99214 (52.1K claims, $2 avg paid/claim, $104.2K revenue, 0.1% of Medicaid revenue; ranks 11 of 14681, 100th percentile; extreme outlier) and 99213 (69.7K claims, $1 avg paid/claim, $69.7K revenue, 0.1% of Medicaid revenue; ranks 25 of 14191, 100th percentile; extreme outlier). These counts show the organization records substantial visit-level activity across typical E/M CPTs even though those codes contribute minimally to revenue.

    Several immunization and procedure codes appear as high-state-percentile outliers, reinforcing a broad ambulatory service footprint: 90747 (631 claims, $63 avg paid/claim, $39.8K revenue; ranks 1 of 9, 100th percentile; notably above typical state volume) and 90674 (3.2K claims, $3 avg paid/claim, $9.5K revenue; ranks 1 of 171, 100th percentile; extreme outlier). These rankings suggest vaccination and preventive services are delivered at scale alongside bundled clinic encounters.

    From a payer/contracting perspective, COOK COUNTY’s lack of Medicare billing and $85.9M Medicaid dependence imply material payer-concentration risk: any changes in Medicaid policy, reimbursement rates, or managed-care relationships could have an outsized impact on revenue. Analysts should treat this entity as Medicaid-dependent rather than diversified across Medicare and Medicaid.

    Competitive standing is nuanced: for the dominant revenue driver T1015 the provider is a top-tier state player (16 of 846, 98th percentile), while for many E/M and vaccine codes the provider appears as an extreme outlier (multiple codes at the 100th percentile and several rank #1 entries). This combination points to a high-volume, clinic-centric operator that ranks among the largest in Illinois for encounter-based and certain preventive services.

    Operationally, the coding and payment pattern—very high-volume T1015 claims with high per-claim average ($335) plus very large counts of low-pay E/M codes—suggests COOK COUNTY packages a broad set of clinic services under an all-inclusive encounter code while still recording discrete E/M and immunization activity. Payer and utilization analyses should therefore focus on encounter-level reimbursement policies and how bundled clinic codes are administered in this provider’s workflow.
