Looking for a settlement you can still file?
This one is closed, but our 60-second eligibility quiz finds the ones that are still open.
Who Was Eligible?
Who the settlement covered:
- You received a data breach notification letter from Datavant or Ciox Health about your personal information being exposed.
- Your personal or protected health information was compromised in the Datavant/Ciox Health data breach.
- You are a U.S. resident whose data was held by Datavant or Ciox Health at the time of the breach.
- You have not previously released your claims against Datavant or Ciox Health related to this breach.
How Much Did It Pay?
There are two ways to get paid from this settlement. If you experienced documented out-of-pocket losses as a result of the data breach — such as fraudulent charges, identity theft-related expenses, or time spent dealing with the fallout — you can claim up to $5,000 in reimbursement. You'll need to provide documentation to support those losses. If you didn't suffer specific financial losses but were still affected by the breach, you can file for a pro rata cash payment drawn from the $900,000 settlement fund. The exact amount of this payment will depend on how many people file valid claims, so the sooner you file, the better. All eligible claimants may also receive identity monitoring services at no cost.How this claim was filed
