The Dimock Center is committed to protecting the privacy and security of our patients’ information. We are posting this notice to inform the community about a data security incident involving TriZetto Provider Solutions (TPS), a vendor that provides insurance eligibility verification services used by many healthcare organizations nationwide. 

Although this incident did not involve our internal systems, some of our patients’ information was involved through TPS. This notice explains what happened, what information was affected, and what patients can do.

What Happened 

On October 2, 2025, TPS detected suspicious activity within a web portal used by certain healthcare providers to access its systems. TPS immediately began an investigation, engaged external cybersecurity experts, and notified law enforcement. 

After completing a detailed review, TPS confirmed that an unauthorized party accessed certain insurance eligibility verification records beginning in November 2024. TPS began notifying affected providers, including our organization, on December 23, 2025.

  • Health insurance member number (including Medicare identifiers) 
  • Health insurer name 
  • Provider name 
  • Primary insured or dependent information 
  • Other demographic or health insurance-related details
