Millstone Medical Outsourcing LLC officially reported a data breach incident to regulatory bodies in Indiana on September 18, 2026. This filing confirms a security event that took place around December 15, 2025, affecting individuals whose sensitive information was entrusted to the company.

According to the official notification, the types of data exposed in this breach include Full Name, Social Security Number, Date of Birth, Mailing Address, Wage and Compensation Information, Driver's License Number, Financial Account Details, and Internal Employee Identification Numbers.

The compromise of such comprehensive personal and financial identifiers carries substantial risks for those affected. This type of information is frequently targeted by criminals for identity theft, opening fraudulent accounts, or attempting unauthorized financial transactions. The inclusion of Social Security Numbers and Financial Account Details significantly elevates these risks.

Individuals who believe they may be affected by this breach should take proactive measures to protect their personal and financial security. It is highly recommended to regularly monitor financial statements and credit reports for any unusual activity. Placing a fraud alert or security freeze with the major credit bureaus can also help prevent unauthorized access to credit.

This information is based on public data breach filings submitted to state regulators. The company indicated that the investigation into the incident was in a 'monitoring' status at the time of the report.

Commonly recommended next steps

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.
Guard against tax fraud
File your tax return as early as possible and consider requesting an IRS Identity Protection PIN so no one can file a fraudulent return in your name.
Watch your financial accounts
Review bank and card statements for unfamiliar activity and turn on transaction alerts. Report anything you don't recognize to your bank right away.
Replace exposed ID documents
Contact your state DMV or the issuing agency about replacing an exposed driver's license, passport, or government ID number.
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.
