Quantum Health, Inc. has officially reported a data breach to the Washington Attorney General on August 14, 2026. This notification confirms that a security incident occurred, potentially affecting the personal and health information of individuals.
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 exposure of such detailed medical and personal identifiers goes beyond typical identity theft risks, potentially leading to medical identity theft where fraudulent billing or corrupted health records can occur. Because foundational identifiers like Social Security numbers do not change, affected individuals face a lifelong risk of financial fraud and targeted scams.
As a healthcare navigation and care coordination company, Quantum Health handles a vast amount of protected health information and personally identifiable information. This makes its systems a high-value target and places a significant responsibility on the company to secure this data. Organizations handling protected health information are bound by strict regulations like HIPAA, which mandate robust security measures to protect sensitive data.
Receiving a data breach notification letter from Quantum Health confirms that your private information was involved in this incident. It also establishes your legal standing if you choose to explore your options. Modern legal standards recognize that the increased risk of future identity theft and the burden of monitoring your information constitute a harm, even if you haven't experienced direct financial loss yet.
Understanding the specifics of your notification letter in light of official filings is crucial. We encourage you to carefully review the letter from Quantum Health. If you have questions about your legal rights or what steps you can take next, our firm offers a free, no-obligation case review to help you understand your options.
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.
