On or about December 15, 2025, Winters Healthcare was notified of a data security incident involving TriZetto, a third‑party company that works with its electronic medical record system provider, OCHIN. According to the notice, an unauthorized individual gained access to one of TriZetto’s systems, and TriZetto took immediate steps to stop the unauthorized activity and secure its environment.
After learning that the incident may have impacted certain patients, Winters Healthcare began working closely with OCHIN to understand what occurred and to ensure appropriate protections were in place for patient information.
Following this review, Winters Healthcare began issuing written notification letters to patients whose information may have been involved in the incident. TriZetto indicated that additional information and updates may be provided as the investigation continues.
Winters Healthcare is a medical provider located in California and relies on third‑party vendors to support its electronic medical record system.
The breach occurred at a vendor level, outside Winters Healthcare’s internal systems.
Following the incident, Winters Healthcare stated it continues to work with OCHIN to monitor vendor security compliance and is reviewing its own internal processes to reduce the risk of future incidents.
If you received a data breach notification letter from Winters Healthcare, it confirms that your personal information may have been involved in the TriZetto security incident.
What information is involved in the Winters Healthcare Data Breach?
Compromised information may include:
First Name
Last Name
Social Security Number
Date of Birth
Contact Information
Health-related Information
Insurance Information
Your Personally Identifiable Information (PII) includes information that can be used to identify you. Healthcare providers and their vendors are legally required to protect this data. When PII is exposed during a data breach, it can be used by cybercriminals to commit identity theft or financial fraud.
A subset of the exposed information in this incident may qualify as Protected Health Information (PHI). PHI includes medical and insurance data and is protected under federal and state privacy laws. When PHI is compromised, it can be used to commit medical identity theft, insurance fraud, or other crimes—often in combination with other personal data.
If your information was involved in a healthcare data breach, one of the most important steps you can take is to carefully review medical bills, insurance statements, and financial accounts for suspicious activity and follow any directions provided by TriZetto or its notification vendor, Kroll, regarding identity theft protection services.
Residents of California benefit from enhanced privacy protections under the California Consumer Privacy Act (CCPA), as well as additional medical privacy protections under California law. Patients may have legal rights when healthcare providers or their vendors fail to adequately safeguard sensitive medical information.
If you received an Important Notice of Security Incident and Breach of Personal Information letter related to Winters Healthcare and the TriZetto breach, your personal, financial, and medical information may be at risk.
