CENTRAL COUNTIES HEALTH CENTERS, INC. operates primarily as a Federally Qualified Health Center-style clinic network with heavy Medicaid activity and no Medicare billing on file; lifetime Medicaid revenue is $32.5M while Medicare shows none, indicating the organization is effectively single-payer (Medicaid)-focused in the available dataset. The NPI was enumerated on 2005-10-13 (~21 years ago), signaling long-standing participation in public programs and suggesting established clinic operations and patient panels. Revenue concentration is extreme: T1015, D0999, and T1040 together account for the vast majority of Medicaid revenue (precomputed top 3 codes account for 99.4% of total Medicaid revenue), with T1015 alone representing $26.4M (81.3% of Medicaid revenue), underlining a dependence on an all-inclusive clinic visit/encounter reimbursement model. T1015 ranks #22 of 846 providers in-state (98th percentile), so the provider is a major statewide participant for this code and delivers unusually high volume of comprehensive clinic encounters compared with peers. D0999 accounts for $5.3M (16.3% of Medicaid revenue) and ranks #2 of 219 providers in-state (100th percentile); this code’s classification as an extreme outlier indicates exceptionally high utilization of unspecified or miscellaneous dental/ancillary billing relative to other in-state providers. T1040 contributes $576.9K (1.8% of Medicaid revenue) for Medicaid certified community behavioral health clinic services and ranks #10 of 191 providers in-state (95th percentile), suggesting the organization also maintains a notable behavioral health per-diem service line alongside its primary clinic visit volume. The provider shows concentrated dental and preventive service activity in addition to medical/behavioral care: multiple dental codes (D0140, D1120, D7140, D0150, D1110 and others) appear in the top Medicaid codes with high in-state ranks (many in the 95th–100th percentiles), which implies an integrated oral health offering contributing smaller shares of revenue but high procedure volumes relative to peers. Several common outpatient and preventive codes (99213, 99214, 90832, 90471, D0220, D1206, 83036) appear with very high claim volumes but $0 paid/claim reported in the dataset; these entries are extreme outliers in rank and indicate widespread use of evaluation/management, behavioral health, immunization, radiology, preventive fluoride treatment, and A1C testing services, though they do not drive recorded Medicaid revenue in the provided payment fields. Overall, the billing profile indicates a clinic-centric operation with Medicaid as the primary payer, a concentrated revenue base around comprehensive clinic visit reimbursement (T1015) plus a substantial miscoded/unspecified dental category (D0999), and notable behavioral health per-diem activity (T1040); these patterns mark the provider as a dominant Medicaid Medicaid-volume player in several service lines within Illinois.
