The $900,000 Datavant Group class action settlement received preliminary approval from the court on April 17, 2026. The deal covers all individuals whose private information may have been compromised in the May 2024 Datavant data breach.

Approximately 58,309 people are covered by the settlement, court documents state.

The court-approved website for the Datavant Group data breach settlement can be found at DatavantDataIncidentSettlement.com.

Datavant settlement class members who file a valid, timely claim form can receive up to $5,000 for documented losses stemming from the breach. Losses covered by this benefit include telephone charges, cell phone minutes, internet charges, the purchase of credit reports and credit monitoring services between May 9, 2024 and August 18, 2026, and more.

Class members must submit proof, such as receipts or bank statements, to receive a documented-loss payment.

In lieu of a documented-loss payment, class members can instead file a claim form to receive an alternative pro rata cash payment, with no proof required. The final amount of this cash payment will depend on the total number of valid claims filed.

In addition to either monetary relief option, all class members can file a claim form to receive an enrollment code for one year of expanded identity theft and fraud monitoring, which includes one-bureau credit monitoring and identity theft insurance.

To file a Datavant settlement claim form online, class members can head to this page and log in using the class member ID listed on their copy of the settlement notice. Alternatively, class members can download a PDF of the claim form to print, fill out and return by mail to the settlement administrator.

All Datavant settlement claim forms must be submitted online or by mail by August 18, 2026.

The court will determine whether to grant final approval to the Datavant Group settlement following a hearing on September 4, 2026. Compensation will begin to be distributed to class members only after final approval is granted and any appeals are resolved.

The Datavant Group class action lawsuit claimed that the healthcare data accessibility platform failed to implement proper cybersecurity safeguards to protect the sensitive information in its care, which supposedly allowed an unauthorized actor to access an employee's email account via a phishing attack on or around May 9, 2024.

Per court documents, private information potentially compromised as a result of the data breach included names, dates of birth, addresses, contact information, Social Security numbers, driver’s license and passport numbers, financial account information and health information.
