Who Is ZOLL Medical and Why Are They Being Sued for a Data Breach?

ZOLL Medical makes the LifeVest, a wearable defibrillator that heart patients strap on when they’re at risk of sudden cardiac arrest. That means the company sits on years of patient records — names, birth dates, Social Security numbers — for people managing a serious heart condition, not casual shoppers with a loyalty account. In early 2023, ZOLL says it detected unauthorized access to its internal network and later confirmed intruders had reached files containing that patient data. The lawsuit argues ZOLL had a duty to lock that information down and didn’t.

What Did ZOLL Medical Do to Affected Patients Between January 22-24, 2023?

According to the official settlement notice, someone gained unauthorized access to ZOLL’s internal computer network between January 22-24, 2023, in an incident the company calls the “Data Incident.” ZOLL began mailing breach letters to affected people in March 2023, and multiple law firms that investigated the breach separately have put the number impacted at more than one million.

Plaintiff Robert Smith sued first, and his case was later consolidated with several others into one class action lawsuit attorney teams pursued together in Massachusetts federal court. ZOLL tried to get the whole case thrown out. It didn’t work — not entirely. In 2025, the court dismissed some state consumer-protection claims but let negligence claims move forward under the laws of six different states, along with breach of fiduciary duty and unjust enrichment claims. ZOLL denies all claims alleged against it and isn’t admitting wrongdoing by settling. That’s standard. But this deal came together after a judge already decided the core negligence theory had legs — not before.

If your name, Social Security number, or birth date was in ZOLL’s system that week in January 2023, this is the case built around exactly what happened to you.

Who Qualifies for the ZOLL Medical Data Breach Settlement?

Here’s exactly how to know if this case includes you.

• Anyone who received a written notice from ZOLL about the January 2023 Data Incident
• Current or former users of the LifeVest wearable defibrillator whose records were on ZOLL’s network at the time
• People whose Social Security numbers were confirmed impacted — these are “SSN Subclass Members” and get a bigger pro rata share
• Those whose personal information was accessed but SSNs weren’t involved — the “Non-SSN Subclass”

You do not qualify if you never received a Data Incident notice from ZOLL, or if you already excluded yourself from a related settlement. ZOLL’s officers, directors, and the judge overseeing the case are also excluded by definition — standard language, nothing unusual there.

ZOLL Medical Patients Outside Massachusetts — Are You Still Covered?

Yes. This is a nationwide settlement class. It doesn’t matter what state you live in or where you used your LifeVest device — if ZOLL sent you a Data Incident notice, you’re in the class regardless of location.

Not sure if you qualify for the ZOLL Medical data breach settlement? A free consultation with a data privacy attorney can help before the September 2 deadline, especially if you’re weighing whether to file for documented losses instead of the flat cash payment.

How Much Can ZOLL Medical Data Breach Settlement Class Members Get?

Two separate benefits are on the table, and you can only pick one cash option per person.

ZOLL Payout With Proof — Up to $5,000

If the breach cost you money — fraud charges, credit freeze fees, notary and mailing costs, credit monitoring you paid for yourself — you can file a claim for actual documented losses up to $5,000. You’ll need receipts or statements; handwritten notes alone won’t cut it.

ZOLL Payout Without Proof — Estimated $50 to $100

If you’d rather skip the paperwork, you can take the pro rata cash payment instead. Non-SSN Subclass Members are estimated at $50. SSN Subclass Members get two shares instead of one, estimated at $100. More people filing means smaller checks for everyone — that’s what “pro rata” means here.

Payments over $600 may appear on a 1099. Check with a tax professional before you spend it. Class Counsel plans to ask the court for attorneys’ fees of up to one-third of the $3.5 million fund, plus litigation expenses, before any class payments go out. That’s fairly standard for a case this size — but it’s worth knowing the fund gets smaller before your check gets cut.

Should ZOLL Medical Class Members Opt Out or Object Before August 3, 2026?

What Opting Out of the ZOLL Settlement Actually Means

Opting out means no payment, but you keep your right to sue ZOLL separately over this breach on your own. Most people shouldn’t opt out without talking to a lawyer first — you’d be walking away from a guaranteed payment for an uncertain one. The opt-out deadline is August 3, 2026.

How to Object to the ZOLL Settlement

You can stay in the class and still tell the court you disagree with some part of the deal — the fee request, the payout amounts, anything. Objections must be mailed to Class Counsel and defense counsel, postmarked no later than August 3, 2026, and must include your name, the case number, and your specific grounds for objecting.

Talk to a class action lawsuit attorney before August 3 if you’re considering either option — once that date passes, both doors close.

For comparison, Anne Arundel Dermatology’s $2.4 million data breach settlement uses this same two-tier structure — a documented-loss claim up to $5,000 alongside a smaller no-proof cash payment — so if you’ve filed one of those claims before, this process will feel familiar. Bayhealth Medical Center’s $2.5 million data breach settlement is another recent example of a healthcare provider paying out after a network security failure, if you want to see how a similar case played out from filing to payment.

ZOLL Medical Data Breach — Frequently Asked Questions, No. 1:23-cv-10575

Do I need a lawyer to file a ZOLL Medical data breach settlement claim? 

No. The online claim form at heartdevicedatasettlement.pnclassaction.com walks you through it directly. A consumer rights lawyer only becomes useful if you’re considering opting out or you have unusually large documented losses.

Is the ZOLL Medical data breach settlement legitimate?

 Yes. It’s a real settlement in Smith et al. v. ZOLL Medical Corporation, No. 1:23-cv-10575, pending in the U.S. District Court for the District of Massachusetts, with EisnerAmper appointed as administrator by the court.

When will ZOLL Medical settlement payments be sent?

 Not before the Final Approval Hearing on September 10, 2026. If the court approves the deal and no one appeals, payments follow after that. Appeals can push the timeline out further.

What if I missed the ZOLL Medical claim deadline?

 Claims postmarked or submitted online after September 2, 2026 typically aren’t accepted. Contact the administrator directly at 1-844-518-0188 to ask about your specific situation.

Will my ZOLL Medical settlement payment go on a 1099? 

Payments over $600 may be reported. Talk to a tax professional about how your specific payout — pro rata cash or documented-loss reimbursement — gets treated.

How much will I get from the ZOLL Medical settlement if my Social Security number was exposed?

 If your SSN was impacted, you’re an “SSN Subclass Member” and get two pro rata shares instead of one — estimated around $100 before final calculations, plus you can still file separately for documented losses up to $5,000.

Is there a lawsuit against ZOLL Medical besides this settlement?

 This case, No. 1:23-cv-10575, is the consolidated action covering the January 2023 breach. ZOLL has faced separate, smaller data security investigations tied to a later 2023 incident, but this settlement only resolves claims from the January breach.

Do I qualify for the ZOLL Medical settlement if I only used the LifeVest years ago?

 Qualification depends on whether ZOLL had your information on file and sent you a Data Incident notice — not on when you used the device. If you got a notice, you’re in the class.
