Multiple Healthcare Data Breaches Expose Patient Information
Several healthcare organizations in the United States have reported significant data breaches resulting in the exposure of protected health information (PHI) for tens of thousands of patients. TriZetto Provider Solutions, a revenue management service provider, discovered unauthorized access to its web portal dating back to November 2024, with attackers accessing historical eligibility transaction reports containing sensitive patient data such as names, addresses, Social Security numbers, and health insurance details. The breach was detected in October 2025, after which immediate remediation steps were taken, including engaging Mandiant for investigation and securing the affected systems.
Other incidents include breaches at Morton Drug Company in Wisconsin, Physicians to Children & Adolescents in Kentucky, the Center for Urologic Care of Berks County in Pennsylvania, North Atlantic States Carpenters Health Benefits Fund in Massachusetts, and Millcreek Pediatrics in Delaware. These breaches involved unauthorized network access and resulted in the exposure of PHI, including names, birth dates, medical record numbers, prescription information, and, in some cases, Social Security numbers. Affected organizations have notified impacted individuals and are offering credit monitoring services where appropriate, while also implementing enhanced security measures to prevent future incidents.

Major Data Breaches Impacting US Healthcare Providers
Cognizant Technology Solutions, through its subsidiary TriZetto Provider Solutions, experienced a significant data breach that went undetected for nearly a year, exposing sensitive personal information such as Social Security numbers, financial account details, and home addresses. The breach, which affected at least 100 individuals across several states, led to multiple class-action lawsuits alleging delayed disclosure, insufficient notification to victims, and a lack of transparency regarding the incident's root cause and remediation. Plaintiffs argue that the delay in notification left affected individuals vulnerable to identity theft and financial fraud, while Cognizant and TriZetto have offered limited public comment due to ongoing litigation. Separately, Covenant Health, a major healthcare provider operating in several northeastern US states, suffered a ransomware attack by the Qilin group in May 2025. The attack compromised the data of over 478,000 individuals, leading to system shutdowns across hospitals and clinics and prompting the organization to hire cybersecurity experts for containment and investigation. Covenant Health initially reported a smaller number of affected individuals but later updated the total to nearly half a million, subsequently notifying patients and offering credit monitoring and identity protection services. Both incidents underscore the persistent cybersecurity risks facing the healthcare sector and the significant impact of breaches on patient privacy and organizational trust.
