Quantum Health, Inc. data breach

Clerk's notes

Quantum Health, Inc., a healthcare navigation and care coordination company, recently filed a report with the Washington Attorney General regarding a data breach. The filing, dated August 14, 2026, indicates that an incident occurred involving the unauthorized access to sensitive information managed by the company.

The exposed data categories 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. The compromise of such comprehensive personal and medical records poses significant risks, including medical identity theft, fraudulent billing, and the potential for corrupted health histories. Additionally, core identifiers like Social Security Numbers can lead to years of elevated risk for financial fraud and account takeovers.

As an entity handling protected health information, Quantum Health operates under stringent regulations such as HIPAA and state data protection laws. These frameworks mandate robust security measures to safeguard sensitive data. A breach of this magnitude suggests potential deficiencies in maintaining these required administrative, physical, and technical safeguards, prompting questions about the adherence to cybersecurity protocols prior to the incident.
