United Medical Systems Inc, a specialized provider in healthcare technology, reported a data security incident to the Indiana Attorney General on May 20, 2026. This breach stemmed from an event on December 19, 2025, where unauthorized actors gained access to its network environment.

The compromised information includes Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Prescription Information, and Provider and Treatment Dates.

To help mitigate potential risks, individuals affected by this breach should review their credit reports regularly and consider placing a fraud alert or security freeze on their credit files. It is also advisable to monitor Explanation of Benefits (EOB) statements from health insurers for any unfamiliar services and to be cautious of unsolicited communications requesting personal information.

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.
