City Ambulance Service Data Breach Exposes Texas Patient Information

Viking Enterprises, Inc., operating as City Ambulance Service, submitted a data breach notification to Texas regulators on September 1, 2026. The company, which provides emergency medical services across Texas, indicated that the security incident took place on July 3, 2026. The breach type was unspecified, and the investigation into the incident is currently listed as monitoring.

The data categories reportedly exposed in this breach are Full Name, Date of Birth, Social Security Number, Medical Record Number, Health Insurance ID Number, Diagnosis and Treatment Information, Provider and Treatment Dates, and Billing and Financial Information. This combination of personal identifiers and detailed medical records is considered highly sensitive.

Individuals who receive an official notification regarding this breach should review the information provided by City Ambulance Service. It is important to understand which specific data types pertaining to them may have been affected.

As a general precaution, those potentially impacted by a data exposure should consider regularly checking their financial account statements and explanation of benefits (EOB) statements from their health insurer for any unusual or unauthorized activity. Monitoring credit reports for unfamiliar inquiries or accounts can also help detect potential identity theft.

Placing a fraud alert on credit files with the major credit bureaus (Equifax, Experian, and TransUnion) can add an extra layer of security. Alternatively, a security freeze can restrict access to credit files, making it more difficult for unauthorized parties to open new accounts in your name. Detailed instructions for these steps are available from the credit bureaus.
