On December 12, 2025, Mission Neighborhood Health Center (MNHC) was notified by OCHIN, its business associate that supports MNHC’s Epic electronic health record system, of a data security incident involving one of OCHIN’s third-party subcontractors, TriZetto Provider Solutions (TriZetto), a healthcare eligibility and claims clearinghouse.

MNHC is issuing this statement to provide clarity, transparency, and reassurance regarding this security incident.

MNHC confirms that its internal systems were not breached or compromised. The incident occurred within the systems of TriZetto.
