  • Medical Record Number

Cerner Corporation, a leading provider of healthcare information technology, recently disclosed a data security incident affecting individuals in Texas. This breach, discovered on January 22, 2025, and reported on October 2, 2026, involves the exposure of deeply personal health and identifying details.

The compromised data types include Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates. The exposure of such comprehensive medical and personal identifiers puts affected individuals at significant risk. This can lead to medical identity theft, where fraudsters might obtain healthcare services under your name, and increased vulnerability to financial fraud.

As a custodian of vast amounts of sensitive health data, Cerner Corporation is legally obligated under federal and Texas state laws, including HIPAA, to protect this information with robust security measures. The occurrence of this breach suggests that Cerner may have failed to uphold these critical duties, potentially leaving patient data vulnerable to unauthorized access. Our firm is actively monitoring this situation and investigating potential claims against the company.

If you have received a formal data breach notification letter from Cerner Corporation, it indicates that your sensitive information was compromised in this incident. Receiving this letter gives you legal standing to pursue potential claims. You do not need to have already experienced financial loss or identity theft to explore your legal options. We are currently investigating class action claims on behalf of affected individuals in Texas on a contingency fee basis, meaning there are no upfront costs to you.

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.
