TriZetto Provider Solutions Data Exfiltration Affecting Healthcare Client Insurance Data
TriZetto Provider Solutions (a Cognizant business unit providing revenue cycle management and claims clearinghouse services) is notifying more than 3.4 million individuals after investigators determined threat actors accessed and exfiltrated healthcare clients’ insurance-related data. The activity reportedly began in November 2024 but was not detected until October 2025, indicating a prolonged period of unauthorized access before discovery.
The incident was reported to the U.S. Department of Health and Human Services via the HIPAA Breach Reporting Tool as impacting approximately 3.43 million people, while TriZetto has not publicly specified how many healthcare customers were affected. Multiple healthcare organizations have publicly stated they were impacted and have issued their own patient notifications, underscoring downstream exposure risk for providers relying on TriZetto’s billing and claims processing services.
