Lake Regional Health System Data Breach

Lake Regional Health System (LRHS) has recently notified its patients about a data breach involving Cerner Corporation, a third-party electronic health record vendor. While LRHS’s own systems were not compromised, sensitive patient information may have been exposed through Cerner’s legacy systems. Affected individuals should understand their rights and take necessary precautions to protect their personal information, as well as explore legal options for compensation.

Lake Regional Health System Data Breach Investigation

In late October 2025, LRHS learned from Cerner Corporation about a data security incident that may have involved certain patient information stored within Cerner’s systems. The breach occurred in February 2025, when Cerner identified unauthorized access to protected health information in their legacy systems. LRHS immediately began working with Cerner and external cybersecurity specialists to determine the scope of the breach, although no disruption to clinical operations at LRHS was reported.

Cerner’s investigation, which involved law enforcement oversight, confirmed that only legacy Cerner systems were affected. Law enforcement directed Cerner to delay notification until the investigation could proceed without interference. Now that law enforcement has allowed notifications to be sent, LRHS is notifying potentially impacted individuals about the breach.

When Did This Breach Occur?

Cerner became aware of the breach in February 2025 but was instructed to delay notifications until the investigation was complete. LRHS was notified of the incident in October 2025, and notifications to affected individuals are now being issued.

What Information Was Breached?

While no financial account information has been reported as compromised, the breach potentially exposed the following types of personal health information:

• Names

• Dates of Birth

• Medical Record Numbers

• Social Security Numbers

• Other Personal Health Information used to provide care

The compromised data is limited to legacy Cerner systems and does not involve any data from LRHS’s own IT systems.

What You Can Do

If you were potentially impacted by this breach, here are some steps you can take to protect your personal information:

1. Enroll in Free Credit Monitoring Services: LRHS is offering free 3-bureau credit monitoring for two years to affected individuals through Experian. This service will allow you to monitor your credit reports for any unauthorized activity or errors.

2. Monitor Your Credit Reports: Regularly review your credit reports for any signs of suspicious activity. You are entitled to one free credit report annually from each of the three major credit bureaus.

3. Use Identity Protection Services: In addition to credit monitoring, LRHS is offering internet surveillance services to help detect any misuse of your personal information online.

4. Place a Fraud Alert or Credit Freeze: Consider placing a fraud alert or security freeze on your credit files with the three major credit bureaus. This will make it harder for anyone to open new accounts in your name without your consent.

5. Report Suspicious Activity: If you notice any fraudulent activity or unauthorized accounts, report it immediately to your financial institution, healthcare provider, or insurance company.

By remaining vigilant and monitoring your personal information, you can reduce the risk of identity theft and fraud.
