Central Ozarks Medical Center data breach

Clerk's notes

Central Ozarks Medical Center filed a report with the Montana Attorney General’s office on January 9, 2026, regarding a data security event that took place on November 10, 2025. The investigation into this incident remains under monitoring by authorities, underscoring the ongoing assessment of its full scope and impact.

The reported breach involved the exposure of several categories of sensitive personal health information. These included 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, and Billing and Financial Information. The wide array of compromised data indicates a significant security lapse.

Exposure of such comprehensive personal and health records carries substantial risks for affected individuals. Unlike a compromised credit card that can be easily replaced, information like your Social Security Number or detailed medical history is permanent. This increases the potential for medical identity theft, where fraudulent parties might use your information to obtain medical services, potentially corrupting your official health records. Victims also face elevated risks of financial fraud, targeted phishing schemes, and other forms of identity theft.

As a healthcare provider, Central Ozarks Medical Center is subject to strict federal and state regulations, including HIPAA and HITECH, which mandate robust data protection measures. A breach of this nature suggests that the required administrative, physical, and technical safeguards may have been insufficient or improperly maintained. These security protocols are designed to prevent unauthorized access to the sensitive patient data entrusted to medical organizations.
