The Illinois Department of Human Services inadvertently exposed HIPAA-protected personal information for over 700,000 residents by publicly posting planning maps on a mapping website from 2021–2025; affected records included names, addresses and benefits status for disabled customers and Medicaid/Medicare Savings recipients. The agency reported no known misuse, disclosed the incident in January, and implemented a policy prohibiting staff from placing customer-level data on public mapping platforms.
