The $7.5 million Thompson Coburn class action settlement received preliminary approval from the court on April 7, 2026. The deal covers all individuals in the United States who were sent notice of the May 2024 data breach.

Court documents state that approximately 377,211 individuals were affected by the breach, the majority of whom were current and former patients of one of Thompson Coburn’s clients, Presbyterian Health Services.

The court-approved website for the Thompson Coburn data breach settlement can be found at TCDataSettlement.com.

Thompson Coburn settlement class members who file a valid, timely claim form can receive up to $5,000 for documented out-of-pocket losses incurred between May 28, 2024, and July 23, 2026 due to the data breach. This benefit covers losses related to identity theft or fraud, as well as expenses for credit monitoring, replacement IDs, postage, notary fees 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 a pro rata cash payment of approximately $150. No proof is required to claim this benefit.

Both cash payments may be reduced pro rata depending on the number of valid claims filed, per the settlement site.  

Finally, in addition to either monetary benefit, all class members are automatically eligible to receive three years of CyEx Medical Shield Complete, which includes three-bureau credit monitoring and medical identity theft insurance.

Court documents state that class members do not need to file a claim to receive this benefit and that they can use the enrollment code in their class action notices to activate the service after the settlement has received final approval.
