Corewell Health Data Breach Exposes Thousands of Patients’ Sensitive Information
In early 2024, Corewell Health disclosed a data breach affecting approximately 19,000 patients, stemming from a security incident at its former vendor, Pinnacle Holdings. The consulting firm, which previously provided healthcare services to Corewell, experienced the breach, compromising a range of sensitive data.
The exposed information included names, contact details, Social Security numbers, medical records, and insurance information. While Pinnacle Holdings stated it had implemented additional safeguards and found no evidence of fraudulent activity, Corewell Health conducted a review to identify impacted individuals.
Affected patients were notified by mail and offered free credit monitoring and identity protection services. Additional support is available through a dedicated call center at 866-686-2607 and on Pinnacle Holdings’ website. The incident highlights ongoing risks in third-party vendor security within the healthcare sector.
