ERMI LLC, a company specializing in rehabilitative medical devices, filed a data breach notification with the California Attorney General's office on May 26, 2026. This report concerns a security incident that occurred on or about February 15, 2025, which led to the compromise of confidential patient information.

The nature of the breach was not specified in public filings, but it impacted the extensive administrative, logistical, and clinical records that ERMI LLC maintains for patients. The company works with healthcare providers to deliver therapeutic equipment, making it a repository for significant amounts of personal and health data.

The exposed data includes a comprehensive set of sensitive personal and health details. Specifically, the breach compromised individuals' Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, Provider and Treatment Dates, Home Address, and Phone Number.

Such a combination of exposed data types creates a heightened risk for affected individuals. The compromise of Social Security Numbers and Dates of Birth can lead to various forms of identity theft and financial fraud. Additionally, the exposure of medical and health insurance information could be exploited for medical identity theft, leading to fraudulent billing or unauthorized acquisition of prescription drugs.

As the investigation into this incident remains ongoing, individuals who receive notification from ERMI LLC should remain vigilant. It is recommended to review explanation of benefits (EOB) statements from insurers for unauthorized services and to monitor financial accounts and credit reports for any suspicious activity. Placing a fraud alert or credit freeze with credit bureaus can also help protect against identity theft.

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.
