Heart Care Centers of Illinois (HCCI) Suffers Major Data Breach, Exposing Sensitive Patient Information
On July 20, 2026, law firm Wolf Haldenstein Adler Freeman & Herz LLP announced an investigation into a data breach at Heart Care Centers of Illinois, S.C. (HCCI), a healthcare provider based in Palos Park, Illinois. The breach may have compromised the personal and medical data of an undisclosed number of individuals.
HCCI disclosed that the incident potentially exposed a wide range of sensitive information, including:
- Personal identifiers: Names, mailing addresses, Social Security numbers, dates of birth, driver’s license/state ID numbers, and passport numbers.
- Financial data: Payment card details and financial account numbers.
- Medical records: Treatment and diagnosis information, prescription details, health insurance data, and provider records.
The firm noted that affected individuals may have received breach notifications and that compromised data could be circulating on the dark web. Wolf Haldenstein, a national consumer rights law firm with offices in New York, Chicago, Nashville, and San Diego, is reviewing potential legal claims for those impacted.
HCCI has not provided further details on the breach’s cause, scope, or timeline, but the exposure of such comprehensive data raises significant concerns about identity theft and fraud risks for affected patients. The investigation remains ongoing.
