Common questions

How many hospitals are in Illinois?

194 hospitals in Illinois are tracked by CMS Care Compare as of the most recent refresh. Of these, 140 are registered as voluntary non-profit (eligible to offer charity care under ACA §501(r)) and 124 have a published CMS overall rating.

Which Illinois hospitals offer charity care?

Every voluntary non-profit hospital in Illinois is required by Section 501(r) of the IRS code to offer financial assistance to patients meeting income criteria. The 140 non-profit hospitals listed below all fall in this category. Each hospital's specific Financial Assistance Policy is on its billing webpage; eligibility is typically tied to a multiple of the Federal Poverty Level.

How are these prices determined?

The prices in the comparison table below come from federally-required Hospital Price Transparency machine-readable files (45 CFR §180.50), aggregated across all reporting hospitals in Illinois. Hospital chargemaster prices are the gross billed amounts before any discounts or insurance contracts; median commercial is the typical insurer rate; Medicare allowed is the federally-set baseline. Real bills depend on the specific facility, payer, and service setting.

What's the difference between chargemaster and what I'll actually pay?

Chargemaster is the hospital's published gross price — rarely what anyone actually pays. Insured patients pay their plan's negotiated rate (typically 30-60% of chargemaster). Self-pay patients can usually negotiate down further (often by 25-50%) or apply for charity care if the facility is a non-profit. The chargemaster matters as the starting point for self-pay billing and the reference for some insurance contracts.
