Cardiology Associates of Fredericksburg Data Breach Exposes PHI

On June 20, 2025, Cardiology Associates of Fredericksburg, Ltd. reported a data breach to the Massachusetts Attorney General’s office, disclosing that sensitive patient information had been compromised. The breach affected at least 51 individuals in Massachusetts and 26 in New Hampsire, though the total number of impacted patients may be higher across other states.

The exposed data includes a wide range of personally identifiable information (PII) and protected health information (PHI): names, addresses, email addresses, phone numbers, dates of birth, dates of service, cost of service, medical diagnoses and treatment details, health insurance information, and Social Security numbers.

The breach involved unauthorized access to the company’s systems, resulting in the exposure of both PII and PHI. This combination of information is particularly sensitive, as it could be used for identity theft, insurance fraud, or other malicious activities.
