Common questions
- What is the claim deadline for the Cornerstone Healthcare Data Breach Settlement?
- This settlement is closed to new claims — the deadline was May 8, 2026. Once a claim deadline passes you generally forfeit your share, even if you qualified.
- Is the Cornerstone Healthcare Data Breach Settlement notice real, or a scam?
- Postlethwaite & Netterville is the settlement administrator for this case. Claims are filed at cshealthcaresettlement.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
