4.5 Million Individuals Affected by Data Breach at HealthEC

HealthEC says personal information received from business partners was compromised in a July 2023 data breach.

Health technology company HealthEC has disclosed a data breach impacting close to 4.5 million customers of its business partners.

HealthEC provides population health management services, delivering analytics and insights to help healthcare organizations improve patient outcomes.

In an incident notice published on its website just before December, the company explained that, between July 14, 2023, and July 23, 2023, an unauthorized actor accessed certain systems and exfiltrated files entrusted to HealthEC by its business partners.

The stolen files contained personal information such as names, addresses, dates of birth, Social Security numbers, taxpayer identification numbers, medical information, health insurance information, and billing and claims information.

According to HealthEC, its review of the stolen data was completed at the end of October 2023, when it started notifying customers and working with them on notifying the potentially impacted individuals.

While the notification does not say how many individuals were affected, HealthEC informed the US Department of Health and Human Services that the attackers stole the information of close to 4.5 million people.

Impacted HealthEC business partners and customers include Alliance for Integrated Care of New York, Advantage Care Diagnostic & Treatment Center, Beaumont ACO, Corewell Health, Community Health Care Systems, Compassion Health Care, Division of TennCare, East Georgia Healthcare Center, HonorHealth, Hudson Valley Regional Community Health Centers,  Illinois Health Practice Alliance, KidneyLink, Long Island Select Healthcare, Metro Community Health Centers, Mid Florida Hematology & Oncology Centers, P.A, State of Tennessee, University Medical Center of Princeton Physicians’ Organization, and Upstate Family Health Center, Inc.

On December 22, 2023, HealthEC and its business partners started sending out notification letters to the impacted individuals, advising them to remain vigilant against possible identity theft and fraud attacks, to review account and benefits statements, and to monitor free credit reports for any suspicious activity.
