Cerner Corporation officially reported a data security incident to Texas authorities on October 2, 2026, indicating an event that occurred on January 22, 2025. The specific nature of this security breach was not detailed in the public filing, but it involved unauthorized access to sensitive personal information.

The data categories identified as exposed in this incident include Full Name, Date of Birth, and Social Security Number. Additionally, sensitive health-related data such as Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates were also part of the compromise.

It is generally recommended to remain vigilant by monitoring financial statements and explanation of benefits statements for any suspicious activity. Consider placing a fraud alert or security freeze on credit files as a preventative measure.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

Freeze your credit
Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.
Check for medical identity theft
Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.
Stay alert to targeted scams
Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.
Keep your notification letter
Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
