Investigation notes

Quantum Health, Inc., a healthcare navigation company, filed a data breach report with the Oregon Attorney General's office on August 14, 2026. This report confirms that a security incident, which occurred on or about May 29, 2026, led to the compromise of confidential information belonging to its members. The exposed data includes individuals' Full Name, Date of Birth, Social Security Number, Health Insurance ID Number, Medical Record Number, Diagnosis and Treatment Information, Prescription Information, Home Address, and Phone Number.

The exposure of such comprehensive personal and health information carries severe, lasting risks for those affected. Unlike a compromised credit card, which can be quickly replaced, stolen medical records and Social Security Numbers are permanent and cannot be easily changed. This puts individuals at heightened risk for medical identity theft, where fraudsters could obtain unauthorized medical care using their identity, as well as various forms of financial fraud and targeted scams.

As a custodian of sensitive patient data, Quantum Health, Inc. was obligated under laws such as HIPAA, HITECH, and applicable Oregon state regulations to implement robust cybersecurity measures. These mandates include maintaining strong administrative, physical, and technical safeguards to protect confidential information. The occurrence of a data breach of this nature suggests potential failures in upholding these required security standards and in maintaining reasonable and appropriate data protection practices.

If you have received a data breach notification letter from Quantum Health, Inc., this document serves as official confirmation that your private information was compromised. Receiving such a notice typically establishes your legal standing to explore a claim against the company for potential negligence in safeguarding your data. Importantly, individuals often do not need to prove they have already suffered financial loss or identity theft to pursue legal action; the increased, imminent risk of future harm is usually sufficient.

Our law firm is currently investigating this data breach. We operate on a contingency fee basis, meaning there are no out-of-pocket costs or attorney fees for you unless we successfully recover compensation on your behalf. We encourage affected individuals to seek a free case review to understand their legal options.

What our attorneys examine

A cyberattack does not excuse a company from protecting the information it holds. We look at whether Quantum Health, Inc. used reasonable security, how long it kept the data, and how quickly it told the people affected. Those questions decide whether a class action or individual claim is possible. Read more on how ransomware lawsuits work, or browse other incident files in Oregon.
