As another option, class members can elect to receive a pro-rated cash payment of up to $100. This amount may be subject to change based on the money remaining in the settlement fund after the payment of attorneys’ fees and costs, plaintiff service awards and settlement administration costs, the settlement website shares.

Settlement class members will have the option to receive their payouts via check or electronic payment, court documents note.

In addition to monetary compensation, all class members with valid claims will receive a code to enroll in free medical information and identity theft protection from CyEx.

Those who believe they may be a class member but did not receive a class action settlement notice should contact the settlement administrator to confirm their identity and receive their login ID.

Alternatively, class members may download a PDF of the claim form to print, fill out, and return by mail to the address listed near the top of the form.

All City of Hope settlement claim forms must be submitted online or by mail by January 13, 2026.

The class action settlement documents add that class members who submit a valid claim will have 120 days to cash their check after the date of issuance before it expires.
