CITY OF CHICAGO operates as an ambulance services provider based on its top codes; the leading Medicare and Medicaid codes are A0427 (ALS 1 emergency) and A0429 (BLS emergency), indicating a primary focus on emergency transport with substantial advanced life support activity alongside basic life support runs. The code mix (ALS emergency, BLS emergency, and ground mileage A0425) is consistent with a municipal emergency medical transport operation rather than episodic non-emergency transports.
Medicaid revenue dwarfs Medicare revenue for this entity: total Medicare revenue is reported as $12.2M while total Medicaid revenue is $1.23B, making the provider effectively Medicaid-dominant in scale. Given these totals, Medicaid is the primary payer relationship and likely the main driver of operational scale and cash flow.
Revenue concentration is extremely high for both payers: the top 3 Medicare codes account for 98.2% of Medicare revenue, and the top 3 Medicaid codes account for 99.8% of Medicaid revenue. This indicates the provider’s Medicare and Medicaid revenue streams are almost entirely dependent on a small set of ambulance transport and mileage services rather than a broad range of CPT/HCPCS lines.
For Medicare, A0427 generates $9.4M (76.8% of Medicare revenue) and A0429 generates $2.2M (17.8%); together these two emergency transport codes dominate Medicare billing. The precomputed share shows Medicare billing is concentrated in emergency ALS and BLS transports, with mileage (A0425) contributing a small residual share (3.5%).
In the Medicaid market the provider is a state-level dominant outlier: A0427 accounts for $868.2M (70.9% of Medicaid revenue) and A0429 accounts for $345.4M (28.2% of Medicaid revenue), with these two codes alone comprising nearly the entire Medicaid revenue base. Both codes rank #1 in-state (100th percentile; extreme outlier), signaling that CITY OF CHICAGO is the leading source of emergency ambulance billing within Illinois.
The provider’s competitive standing differs by payer: on Medicare the provider is an extreme national outlier for A0427 (ranks #5 of 6841 providers, 100th percentile) and A0429 is also a national extreme outlier (ranks #36 of 7808, 100th percentile), indicating unusually large national-scale volumes for those codes relative to peers. On Medicaid the provider ranks #1 in-state for A0427 and A0429 (100th percentile; extreme outlier), and ranks #2 in-state for mileage A0425, which collectively positions CITY OF CHICAGO as the dominant in-state Medicaid ambulance supplier.
Operational footprint and longevity support sustained activity: the NPI was enumerated on 2006-08-11 (about 20 years ago), indicating long-tenured participation in payer networks and a stable enrollment history that aligns with the large cumulative Medicaid billing observed. Continued dominance in a narrow set of high-volume emergency transport codes suggests ongoing, consistent operational capacity.
Several codes are flagged as statistical outliers across both payers, which reinforces the provider’s atypically high volumes: A0427 and A0429 are described as "extreme outlier, far above typical volume" for Medicare and are #1 in-state for Medicaid (also "extreme outlier"), while A0425 (ground mileage) is "notably above typical" on Medicare and an extreme outlier in-state for Medicaid. These labels indicate the provider’s billing profile is concentrated and materially above peer norms rather than evenly distributed across many codes.
