Investigation notes

Quantum Health, Inc., a specialized healthcare navigation and care coordination company, filed notice of a data breach with the Washington Attorney General's office on August 14, 2026. Given its role as a critical link between patients, employers, and medical providers, Quantum Health routinely collects and stores a vast amount of sensitive personal and protected health information.

The reported breach involved the exposure of highly sensitive personal and health information. The specific categories of data identified as potentially compromised include Full Name, Date of Birth, Social Security Number, Health Insurance ID Number, Medical Record Number, Diagnosis and Treatment Information, Prescription Information, Provider and Treatment Dates, Mailing Address, and Phone Number.

Exposure of such comprehensive data carries profound risks. This incident could lead to severe consequences for affected individuals, including medical identity theft, where fraudulent care could corrupt personal medical histories. Furthermore, the compromise of foundational identifiers like Social Security Numbers creates long-term vulnerabilities to financial fraud and account takeovers.

As an entity handling protected health information, Quantum Health operates under stringent federal and state regulations, including HIPAA. These laws require robust security safeguards to protect sensitive data. The occurrence of a data breach prompts an investigation into whether adequate administrative, physical, and technical measures were in place to prevent unauthorized access to this critical information.

If you have received a data breach notice from Quantum Health, we encourage you to review your notification carefully, remain vigilant for any suspicious activity, and consider a confidential case review to understand your rights and options.
