ZOLL Data Breach Settlement 2026: The 'Heart Device Data Settlement' Explained
ZOLL Medical — maker of the LifeVest wearable defibrillator — agreed to a $3.5 million settlement over its January 2023 data breach. If you got a notice, you can claim an estimated $100 (SSN subclass) or $50, or up to $5,000 in documented losses, by September 2, 2026. The official administrator site is literally named heartdevicedatasettlement.com.

What the Lawsuit Alleges
Between January 22 and 24, 2023, unauthorized actors accessed ZOLL Medical Corporation's internal network. The exposed files involved current and former patients who used — or were evaluated for — the ZOLL LifeVest wearable cardioverter defibrillator, and included names, addresses, dates of birth, Social Security numbers, and health information. The class action (Smith et al. v. ZOLL Medical Corp.) alleged ZOLL failed to implement reasonable data security for some of the most sensitive data that exists: cardiac patients' health records. ZOLL denies wrongdoing but agreed to a $3.5 million settlement.
Case Details
U.S. District Court for the District of Massachusetts — Case No. 1:23-cv-10575. Settlement administered by EisnerAmper (heartdevicedatasettlement.com).
Current Status
Who Is Affected & Can You Join?
U.S. residents who received a notice from ZOLL about the January 2023 data incident. There are two subclasses: the SSN Subclass (your Social Security number was potentially exposed) and the Non-SSN Subclass. Eligibility is tied to ZOLL's breach-notification records — if you were a LifeVest patient around 2023 and received (or believe you should have received) a notice, check the administrator site.

Scam & Misinformation Warnings
Whenever a brand lawsuit goes viral, scam sites and bad actors follow. Watch for these red flags:
'Heart device recall' robocalls
This settlement is about a DATA breach, not a device defect or recall. Calls claiming your LifeVest is being recalled and asking for payment data are scams — device safety questions go to your cardiologist, not a settlement line.
Fee-charging claim services
Filing is free at heartdevicedatasettlement.com. Nobody legitimate charges to file a $50–$100 claim for you.
Phishing for your SSN 'to verify your subclass'
The administrator already knows which subclass you're in from ZOLL's records. Emails or calls asking for your full Social Security number to 'confirm your higher payment' are identity theft attempts.
Frequently Asked Questions
Is the 'heart device data settlement' the same as the ZOLL settlement?
Yes. The official administrator site is heartdevicedatasettlement.com, so many people search for it by that name. It covers ZOLL Medical's January 2023 data breach affecting LifeVest wearable defibrillator patients — not any pacemaker or other manufacturer's incident.
How much will I get?
The official estimates are about $100 if your Social Security number was exposed (SSN Subclass) and about $50 otherwise — pro rata, so the real amount depends on how many valid claims are filed. Documented identity-theft losses can be reimbursed up to $5,000 with receipts.
When is the deadline?
September 2, 2026 to file a claim. The opt-out/objection deadline is August 3, 2026, and the final approval hearing is September 10, 2026.
When will checks arrive?
After the September 10, 2026 final approval hearing plus any appeals — realistically late 2026 or early 2027.
I was a LifeVest patient but got no notice. Can I still claim?
Eligibility is determined from ZOLL's notification records, and the FAQ language suggests self-identification without a notice is generally insufficient. Contact the administrator through heartdevicedatasettlement.com to check whether you're in the class before assuming you're excluded.
Does filing affect my medical care or device warranty?
No. The settlement is purely about the data incident. Filing a claim has no connection to your cardiac care, your device, or your insurance.
Separate from this case: were you injured in the last 2 years?
Class-action payouts are fixed amounts through an administrator. A personal injury claim is a different case — and often worth far more. Free estimate, no obligation.
