Great Valley Cardiology Data Breach Investigation


Migliaccio & Rathod is investigating Great Valley Cardiology (GVC) also known as Commonwealth Health Physician Network, for a data breach of over 180,000 of its patients’ personal information.  In February 2023, an unauthorized third party breached GVC’s computer system, stealing patients’ personal information from the company.  This information may include an individual’s name, address, date of birth, Social Security number, diagnosis/condition, health insurance information, driver’s license number, and credit or debit card information.

GVC recently informed patients of this breach through a notification letter and website notice.

All of the information stolen is likely valuable and dangerous. In previous data breaches, victims of data theft have noticed identity theft attempts ranging from fraudulent charges on bank accounts or credit cards, to medical services or government services ordered in their name, to their information being posted on the dark web.
