Based on the data types reported in this filing:
Your SSN is the master key to your identity. Once exposed, criminals can open new lines of credit, take out loans, or file taxes in your name.
Combined with a name and other leaked data, date of birth helps criminals pass identity verification questions at banks and government agencies.
Home address exposure can enable mail theft, package fraud, and targeted phishing attacks that reference your known location.
As a healthcare organization, Quantum Health was entrusted with some of the most sensitive data a person can share. According to a NH state filing, Quantum Health experienced a data security incident affecting an undisclosed number of individuals, exposing protected health information and medical records. This breach was recently disclosed and the window for legal action is open now.
Medical data breaches carry consequences that extend far beyond financial fraud. Stolen health records have been used to obtain controlled prescriptions, falsify insurance claims, and corrupt patients' permanent health histories — damage that can take years to identify and correct. If Quantum Health held your health records, the exposure of that information has serious long-term implications.
Quantum Health appears to be a healthcare navigation and care coordination company operating within the medical and insurance sectors. In the regular course of providing these services, the company typically collects and stores sensitive personal data, including names, dates of birth, Social Security numbers, medical record numbers, health insurance details, and diagnosis or treatment information. This security incident was officially reported to the New Hampshire Attorney General in 2026. If you received a data breach notification letter in the mail, it means your personal information may have been compromised during the incident. This page provides an overview of the event and outlines the specific data types potentially exposed.
Common categories of compensation in data breach class actions
Courts recognize that the time spent monitoring accounts, placing credit freezes, and dealing with the aftermath of a breach has real economic value. This category of damages is recoverable even without direct financial loss.
Professional credit monitoring services cost $10–$40 per month. Identity theft restoration services, if needed, can cost hundreds of hours and thousands of dollars. Courts have awarded these costs as direct damages in SSN breach cases.
HIPAA violations carry civil penalties between $100 and $50,000 per violation. Where a healthcare organization's negligence led to the exposure of protected health information, class members may recover statutory damages in addition to actual losses.
Data breach victims regularly report anxiety, loss of sleep, and ongoing fear of identity theft. These non-economic harms are cognizable injuries in data breach litigation, particularly in cases involving SSN or medical record exposure.
Under the New Hampshire data breach notification law, you may have a legal claim against Quantum Health if any of the following apply:
Applicable State Law
This breach was reported under the New Hampshire data breach notification law, which mandates notification and establishes your right to seek damages.
Received a notification letter from Quantum Health?
Read our dedicated guide — what the letter means and what to do.
No. Under New Hampshire data breach notification law and federal law, the unauthorized exposure of your personal data — regardless of whether it has been actively misused — can be sufficient grounds for a claim. The breach itself is the injury.
Nothing. The Law Office of David S. Harris handles data breach cases on contingency — you pay zero upfront and owe nothing unless compensation is recovered.
Immediately place a free credit freeze at all three bureaus (Equifax, Experian, TransUnion). A freeze blocks new accounts from being opened in your name. Then file a complaint with the FTC at IdentityTheft.gov and contact our office — SSN exposure is one of the most serious breach types.
If Quantum Health is a covered healthcare entity or business associate under HIPAA, affected patients have additional rights — including the right to an HHS complaint. These HIPAA violations also strengthen civil damages claims. Consult an attorney to understand your full remedies.
State statutes of limitations for data breach claims typically run 2–4 years from the date of the breach or its discovery. Because this breach was recently disclosed, the window is open — but acting early preserves your options and strengthens the case.
Accepting free credit monitoring from Quantum Health does not waive your right to pursue legal action unless you signed a specific release waiving claims. In most cases, victims who accepted monitoring can still file.
Not necessarily. Many data breach victims are never notified directly. If your personal information was held by Quantum Health during the relevant period, you may still qualify even without receiving a letter. A free eligibility review can confirm your status.
