Who it's for

McHenry County hospital safety net: McHenry = Northwestern Medicine McHenry + Huntley + Mercyhealth (Crystal Lake/Harvard) + Advocate Good Shepherd. DISTINCTIVE to Illinois: state law (the Hospital Uninsured Patient Discount Act + Fair Patient Billing Act) REQUIRES hospitals to provide financial assistance — uninsured patients at or below 200% (rural/critical-access) or 300% (urban) of the Federal Poverty Level generally receive free care, with capped discounts above that. Most Illinois hospitals have a robust charity-care policy as a result.
