How to read this data
Negotiated Rate
The discounted price an insurer has agreed to pay a specific provider. Most insured patients' bills are calculated from this number, not the higher list price hospitals publish separately.
P5, Median, P95
P5 is the rate at the 5th percentile (low end), Median is the middle value, and P95 is the 95th percentile (high end). This range shows how much the same visit can vary between providers.
What this does not tell you
These rates do not tell you what you personally will pay out of pocket. That depends on your specific plan, how much of your deductible you have already met, your coinsurance rate, and whether the provider is in your network. Call your insurer's member line to get your exact estimate.

Why ER Visit (High) Visit Costs Vary Across Illinois
Illinois emergency care costs run approximately 10% above national averages, driven by Chicago's concentration of major academic medical centers and the state's higher-than-average healthcare worker wages. The Prairie State's geography creates distinct cost regions, from Chicago's dense provider networks to rural counties where emergency access may require longer transport times.
Urban vs. Rural Provider Availability
Chicago's metropolitan area contains dozens of emergency departments within a 50-mile radius, while rural Illinois counties may have only one hospital serving multi-county regions. This geographic disparity affects both access and pricing, as rural emergency departments often charge higher rates to cover fixed costs across smaller patient populations.
Facility Type and Overhead Costs
Illinois features major health systems like Northwestern Medicine, Advocate Health, and Rush University Medical Center that operate hospital-based emergency departments with higher overhead costs. Independent freestanding emergency departments, particularly in suburban markets, may offer lower facility fees but similar physician charges for high-acuity care.
Insurance Market Competition in Illinois
The competitive Illinois market with major players BCBS IL, UHC, and Aetna creates downward pressure on negotiated emergency care rates. This competition particularly benefits patients in the Chicago metropolitan area, where insurers compete aggressively for employer-sponsored group coverage that includes emergency benefits.
Physician Supply and Demand in Illinois
With 13,925 active emergency medicine providers, Illinois maintains adequate emergency physician supply in urban areas while facing shortages in rural regions. This supply-demand imbalance contributes to pricing variations, as rural emergency departments may charge premium rates to attract and retain emergency physicians willing to serve less populated areas.
