Quantum Health, Inc. officially reported a data security incident to the Oregon Attorney General on August 14, 2026. The breach, which occurred on May 29, 2026, involved unauthorized access to systems containing confidential information. While the specific nature of the attack remains undisclosed, it allowed threat actors to potentially access a significant amount of sensitive data.

According to the official filing, the exposed information includes your 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 a comprehensive set of personal and protected health information creates long-term risks. Unlike a compromised credit card, these details cannot be easily changed, leaving victims vulnerable to medical identity theft, financial fraud, and unauthorized access to healthcare services.

As a custodian of your sensitive healthcare data, Quantum Health, Inc. was bound by stringent federal and state regulations, including HIPAA and Oregon's consumer protection laws. These frameworks require robust security measures to protect patient information. A breach of this magnitude suggests potential failures in upholding these mandatory cybersecurity standards, which could indicate negligence on the company's part.

If you have received a data breach notification letter from Quantum Health, Inc., it serves as formal acknowledgment that your confidential information was compromised. This letter establishes your standing to seek legal recourse. You do not need to prove actual financial loss or identity theft to pursue a claim; the increased risk of future harm due to the exposure of your data is sufficient under the law.

It is important to carefully review your notification letter for specific details and deadlines. Understanding what the company's notification means for your legal rights is the first step. Our firm is currently investigating this data breach, and we offer free case reviews to help you understand your legal options without any out-of-pocket costs.

What to do if you were affected

Based on the categories of information reported in this filing, these steps can help limit the risk of identity theft and fraud.

  • Freeze your credit

    Place a free credit freeze with Equifax, Experian, and TransUnion. A freeze blocks new accounts from being opened in your name and can be lifted anytime.

  • Check for medical identity theft

    Review the Explanation of Benefits statements from your health insurer for services or claims you never received, which can signal misuse of your medical identity.

  • Stay alert to targeted scams

    Be cautious of calls, texts, or emails that reference this breach. Legitimate organizations won't ask you to confirm sensitive details through an unsolicited message.

  • Keep your notification letter

    Save the notice you received. It documents that your information was involved and is often needed to enroll in any credit monitoring offered or to join a related legal claim.
