What we know
Quantum Health, Inc. recently reported a data security incident to the Attorney General of Washington, confirming that personal data under its care was compromised. As a company specializing in healthcare navigation and coordination, Quantum Health handles a substantial volume of sensitive information. If you received an official breach notification letter, it indicates your information was part of this exposure.
The compromised data includes very specific categories of personal and medical information. The filing confirms that exposed details include your 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. This combination of identifying and health-related data creates significant risks.
The exposure of such detailed information can lead to various forms of harm. Medical identity theft is a serious concern, where criminals might use your health insurance details to obtain services or prescriptions under your name, potentially corrupting your medical records. The theft of foundational identifiers like your Social Security Number also poses long-term risks for financial fraud, unauthorized account access, and sophisticated phishing attacks.
Upon receiving a breach notification, it is important to take immediate action. Carefully review the letter for any specific guidance provided by Quantum Health. Consider placing a fraud alert or credit freeze with credit bureaus and closely monitor all financial and medical statements for any unusual activity. This vigilance can help detect and mitigate potential misuse of your compromised data.
Understanding the full extent of your rights after a data breach can be complex. You may be entitled to seek compensation for the risks and harms you face, including the time and effort required to protect yourself from identity theft. Consulting with an attorney specializing in data privacy can help you explore your legal options.

- Did Quantum Health, Inc. offer free credit monitoring?
