Quantum Health, Inc. has reported a data breach to Washington authorities, potentially exposing sensitive personal and health information. Our firm is investigating the incident and its implications for affected individuals, particularly concerning the risks of medical identity theft and financial fraud.
DataBreachLawGroup.com has launched an investigation into a data breach recently reported by Quantum Health, Inc. to the Washington Attorney General on August 14, 2026. Quantum Health operates as a critical link in healthcare navigation and care coordination, handling vast amounts of sensitive information for patients and employers across the nation.
The reported breach may have exposed a comprehensive range of personal data. This includes individuals' 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 carries significant and long-lasting risks.
For those affected, the compromise of healthcare-related data, particularly from a navigation provider, can be especially concerning. Beyond general identity theft, medical identity theft can lead to fraudulent billing, incorrect medical records that could jeopardize future care, and a prolonged risk of targeted scams using highly personal information. Core identifiers like Social Security Numbers and Dates of Birth offer criminals a permanent gateway for potential financial fraud.
As an entity handling protected health information, Quantum Health is bound by strict federal and state regulations, including the Health Insurance Portability and Accountability Act (HIPAA), to safeguard this data. A breach involving such extensive personal and health details suggests that the company may not have maintained adequate security measures to protect the sensitive information entrusted to its care.
