Chicago Charges Medicaid 8.5x National Average for Ambulance Rides, Analysis Reveals
Key Takeaways
- ▸Chicago's Medicaid ambulance costs increased 14-fold in six years (2018-2024), from $16.1M to $231.7M annually
- ▸Chicago charges 8.5x the national average per ambulance claim, the highest among major US cities—comparable cities like NYC and LA bill below the national average
- ▸The Illinois GEMT program enables cost-based reimbursement for government ambulance services, allowing Chicago to receive supplemental payments exceeding standard Medicaid fee schedules
Summary
A data analysis using DoltHub's open Medicaid payments dataset reveals that Chicago charges Medicaid $16,000+ per ambulance claim—8.5 times the national median and nearly double Washington DC's rates. The cost to Medicaid for Chicago ambulance service exploded from $16.1 million in 2018 to $231.7 million in 2024, driven largely by the Illinois Ground Emergency Medical Transport (GEMT) program enacted in 2019. This program allows government-owned ambulance services to bill Medicaid based on actual costs rather than standard fee schedules, with Chicago receiving supplemental payments on top of base fees. Despite collecting $300 million annually in ambulance revenue against only $82 million in EMS personnel costs, Chicago's ambulance service generates substantially more revenue than operational expenses, raising questions about cost justification and program sustainability.
- Chicago's ambulance service generates $300M annually in revenue against $82M in personnel costs, suggesting rates may exceed actual operational needs

Editorial Opinion
While DoltHub's AI-powered data analysis demonstrates the power of accessible open data, it also exposes a significant policy vulnerability in how government ambulance services bill Medicaid. The GEMT program's cost-based reimbursement model, while well-intentioned, appears to lack sufficient oversight mechanisms, allowing Chicago to generate revenues that far exceed operational costs. This case underscores why AI-assisted data analysis tools are increasingly critical for healthcare accountability—enabling journalists and researchers to quickly identify outliers and cost anomalies that might otherwise go unnoticed. However, policymakers must now address whether GEMT programs adequately audit and cap reimbursement rates.
