Open Door Community Health Centers experienced a data breach that began in November 2024, stemming from a security vulnerability at their third-party vendor, TriZetto Provider Solutions. The breach was detected in November 2024, and consumers began to be notified around December 2025. TriZetto formally notified HIPAA covered entities, including Open Door, on January 15, 2026.
The compromised data types include Address, Dates of Birth, Social Security Numbers, Health Insurance Member Numbers, Medicare Beneficiary Numbers, Health Insurer Names, Primary Insured/Beneficiary Information, and other demographic health data. While the total number of individuals affected across all TriZetto clients is 3.4 million, the specific number of Open Door Community Health Centers patients affected has not been publicly detailed. It remains unclear if any individuals outside of California have been impacted.
Details surrounding data breaches can emerge over time, and notifications to affected individuals may be delayed.
