Quantum Health Reports Extensive Data Compromise in Washington

Quantum Health, Inc., a company operating in the healthcare navigation sector, submitted a data breach notification to the Washington Attorney General on August 14, 2026. The nature of the breach was not specified in the filing, and the investigation into the incident is currently monitoring the situation.

The records exposed in this incident included a comprehensive range of sensitive personal and health information. According to the filing, the compromised data types were 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 exposure of such detailed information can lead to various risks for affected individuals. Compromised foundational identifiers like Full Name, Date of Birth, and Social Security Number heighten the risk of identity theft and financial fraud. The exposure of health-specific data, such as Medical Record Number and Diagnosis and Treatment Information, can result in medical identity theft, which could impact medical records and future healthcare.

Individuals who may be affected by this incident should take steps to protect their information. It is advisable to review credit reports regularly for any unauthorized activity and consider placing a fraud alert or credit freeze on credit files. Additionally, carefully examine any explanation of benefits (EOB) statements from insurers for unusual medical services. Remain vigilant against suspicious emails, calls, or mail that could be phishing attempts.
