The breach, which occurred on or about February 15, 2025, involved an unspecified type of security incident. Public filings confirm that ERMI LLC is currently monitoring the situation following the compromise of its systems. Organizations like ERMI LLC are often targets for cyberattacks due to the volume and sensitivity of the data they manage.
The exposed data categories include 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. The combination of these data types presents significant risks, potentially enabling identity theft or medical fraud.
Individuals who receive a breach notification from ERMI LLC should carefully review the information provided.

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.
