Understanding the Rankings

CMS Star Ratings

Chicago has two 5-star hospitals — Northwestern Memorial and Rush University Medical Center — both on the Near West and Near North sides. The 4-star tier includes University of Chicago Medical Center (Hyde Park) and Ascension Saint Joseph (Lakeview). Unfortunately, several Chicago hospitals earn just 1 star, highlighting the city's healthcare inequality.

Cost-to-Charge Ratio

Northwestern Memorial's ratio of 0.16 means it charges about 6x actual cost — standard for a top academic center. Ascension Saint Joseph offers a slightly better value at 0.15. Community hospitals like Roseland (0.47) and Saint Anthony (0.43) have higher ratios — meaning lower markups — but also lower quality ratings.

Price Transparency

Rush leads the 5-star tier with 223 priced procedures published — exceptional transparency for a top hospital. Advocate Illinois Masonic and University of Illinois Hospital each publish 227–229 procedures, leading the city overall. Northwestern publishes a respectable 128.

Chicago's Healthcare Divide

Chicago has one of the starkest healthcare divides in the nation. North Side and downtown hospitals earn 4–5 stars, while many South and West Side hospitals earn 1 star. If you have flexibility in where you receive care, the quality data shows significant differences in outcomes. However, access to transportation and insurance network limitations make this more complex than simply "go to the higher-rated hospital."

Tips for Choosing a Hospital in Chicago

Check CMS ratings first. The difference between a 1-star and 5-star hospital in Chicago represents real differences in outcomes, safety, and patient experience.
Compare prices for scheduled procedures. Use Taven's comparison tool with real Chicago hospital data.
Consider Rush for transparency + quality. It's the rare 5-star hospital that also leads in price transparency (223 procedures published).
Ask about charity care. Illinois law requires nonprofit hospitals to offer financial assistance. This includes Northwestern, Rush, and UChicago.
Get a Good Faith Estimate before any planned procedure.
Review your bill. Use our free bill review tool to check for errors.
Check your network. Chicago has many hospital systems with separate insurance contracts. Verify network status before non-emergency visits.
