AltaMed Data Breach: Lawsuit Investigation

Attorneys working with ClassAction.org are looking into whether a class action lawsuit can be filed in light of the AltaMed data breach.

As part of their investigation, they need to hear from individuals who had their information exposed in the incident, including those who received notice of the AltaMed data breach or otherwise believe they are affected.

AltaMed Security Incident: What Happened?

AltaMed Health Services Corporation, a provider of health and human services based in Southern California, recently experienced a data breach that potentially compromised personal information. On December 14, 2025, the company faced a cybersecurity incident affecting certain computer systems. AltaMed activated its incident response plan, secured its systems and enlisted cybersecurity experts to aid in the investigation.

According to a sample data breach letter (pictured below) that appears to be directed to employees, information compromised in the AltaMed Health Services Corporation data breach may include names, addresses, Social Security numbers and compensation details.

A data breach notice posted on the company's website indicates that patient information, including names, dates of service and payment details, may have also been exposed.

This is at least the second data breach AltaMed has experienced in recent years, with the healthcare provider having reported last June that it had been affected by an August 2024 data breach.

What You Can Do After the AltaMed Data Breach

If your information was exposed in the AltaMed data breach, attorneys want to hear from you. You may be able to start a class action lawsuit to recover compensation for loss of privacy, time spent dealing with the breach, out-of-pocket costs, and more.

A successful case could also force AltaMed to ensure they take proper steps to protect the information they were entrusted with.
