Chattanooga Heart Institute Data Breach Class Action Settlement

What is the Chattanooga Heart Institute data breach settlement about?

The Chattanooga Heart Institute data breach settlement (Cahill, et al. v. Memorial Heart Institute LLC d/b/a The Chattanooga Heart Institute) resolves a lawsuit alleging that the Institute failed to implement adequate cybersecurity protections before a cyberattack that occurred between March 8–16, 2023. The breach potentially exposed the personal information of approximately 460,000 current and former patients and employees, including names, addresses, email addresses, phone numbers, dates of birth, driver's license numbers, Social Security numbers, health insurance account information, health records, lab results, and medications.

Chattanooga Heart Institute (which operates as Memorial Heart Institute) denied wrongdoing but agreed to a $3.75 million settlement fund to resolve the litigation. The fund is split into two pools: $2 million for a Social Security Number (SSN) Subclass — patients and employees whose SSNs were exposed — and $1.75 million for the broader Total Class. Compensation options range from up to $5,500 in documented-loss reimbursement to two free years of credit and medical identity monitoring.

Who qualifies to file a claim?
