ERMI LLC operates within the specialized medical technology and healthcare sector, providing rehabilitative medical devices. As part of its services, the company handles extensive administrative, logistical, and clinical records, acting as a central repository for vast amounts of confidential patient information. In May 2026, ERMI LLC officially reported a data security incident to the California Attorney General, indicating a compromise of its network systems.
The data exposed in this security breach is comprehensive and highly sensitive. It includes 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. This specific combination of personal and health data creates substantial risks for affected individuals, ranging from medical fraud and unauthorized billing for services to more profound threats like long-term identity theft and financial fraud.
As an entity entrusted with sensitive medical and personal records, ERMI LLC is bound by strict legal and regulatory obligations. Both federal laws like the Health Insurance Portability and Accountability Act (HIPAA) and California state data privacy statutes require healthcare-related organizations to implement robust safeguards to protect consumer data. The occurrence of a breach of this nature suggests that these mandatory security measures may have been insufficient or improperly maintained.

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.
