ZOLL Medical Corporation is a Massachusetts-based medical technology company that makes cardiac, resuscitation and critical-care devices. According to the settlement notice and the complaint, an unauthorized party accessed ZOLL's network in a data incident in late January 2023, potentially affecting the personal information of patients and employees; for some individuals, the information at issue included Social Security numbers. Plaintiffs allege ZOLL failed to adequately safeguard that information. ZOLL denies any wrongdoing, and no court has decided who is right; the parties agreed to settle to avoid the cost and risk of continued litigation.
The class action, Smith, et al. v. ZOLL Medical Corporation, Case No. 1:23-cv-10575, is pending in the U.S. District Court for the District of Massachusetts. Under the proposed settlement, ZOLL will fund a $3.5 million Settlement Fund. The claim deadline for cash benefits was September 2, 2026. This page explains who qualifies, what you can get, and how to file.

The Settlement Class is defined as all living persons who reside in the United States and to whom ZOLL Medical issued notice that certain personal information was impacted in the January 2023 data incident. The class excludes ZOLL and its officers and directors, anyone who timely and validly requests exclusion, and the judge assigned to the case.
Within the class, a subset of members — those whose Social Security numbers were potentially impacted — qualify for an enhanced cash benefit (see below). If you received a notice from ZOLL about the incident, you are a Settlement Class Member unless you choose to exclude yourself.

The settlement creates a $3.5 million Settlement Fund, from which class members can claim one of the following:
Documented Out-of-Pocket Losses — reimbursement of up to $5,000 per person for documented, unreimbursed out-of-pocket losses fairly traceable to the data incident. Covered examples typically include losses from identity theft or fraud, costs of credit reports, credit monitoring or a credit freeze, fees to replace identification, and certain bank fees tied to documented fraud, all supported by reasonable documentation.
Pro-Rata Cash Payment — a cash payment equal to your pro-rata share of the net Settlement Fund (what remains after documented-loss claims, administration costs, court-approved attorneys' fees and costs, and any service awards). Class members whose Social Security numbers were potentially impacted are eligible for a two-times (2×) pro-rata cash payment, so they can recover more per claim than class members outside that group. Because the payment is pro rata, the exact amount depends on how many valid claims are filed.
The deadline to submit a claim is September 2, 2026. You can file online at the official settlement website, Heart Device Data Settlement.com. Because the class is defined by the people ZOLL notified, the claim process is expected to ask for the identifier printed on your notice; if you are claiming the up-to-$5,000 out-of-pocket reimbursement, you must also provide reasonable documentation supporting each expense (for example, account statements showing unauthorized charges, receipts, or a police report).
If you cannot locate the identifier from your notice, use the contact page on the official settlement website rather than filing without it.
- Exclude yourself (opt out): August 3, 2026
- Object to the settlement: August 3, 2026
- File a claim: September 2, 2026
- Final approval hearing: held September 23, 2026 (moved from September 10) — no ruling posted yet
If you do nothing, you remain in the Settlement Class and give up your right to sue ZOLL over the January 2023 data incident, but you will not receive any payment. The claim deadline was September 2, 2026. Benefits are distributed only after the court grants final approval and the settlement becomes final.
What changed recently: the court moved the final approval hearing from September 10 to September 23, 2026. According to the official settlement website, the court held the hearing on September 23, 2026 at 2:30 p.m. ET but had not yet issued an order on the settlement; the administrator says it will post an update, including the impact on the timing of class member awards, once the court rules. No order had been posted as of October 20, 2026.
Who qualifies for the ZOLL Medical data breach settlement?
The Settlement Class is all living U.S. residents to whom ZOLL Medical issued notice that their personal information was impacted in the January 2023 data incident. If you received a notice from ZOLL about the incident, you are a Settlement Class Member unless you exclude yourself.
How much money can I get from the ZOLL Medical settlement?
The settlement creates a $3.5 million fund. You can claim reimbursement of up to $5,000 for documented out-of-pocket losses fairly traceable to the incident, or a pro-rata cash payment. Class members whose Social Security numbers were potentially impacted can receive a two-times pro-rata cash payment. Because cash payments are pro rata, the exact amount depends on how many valid claims are filed and how much of the fund remains after documented-loss claims and costs.
What is the deadline to file a ZOLL Medical claim?
The deadline to submit a claim was September 2, 2026. The deadline to exclude yourself from or object to the settlement was August 3, 2026. The final approval hearing was moved from September 10 to September 23, 2026; the court held it that day, and no final approval order had been posted on the official settlement website as of October 20, 2026.
