The lawsuit Jackson v. Ciox Health LLC d/b/a Datavant Group, Case No. CV2025-062690, was filed in Maricopa County Superior Court in Arizona and alleges negligence and consumer fraud violations. While Datavant reported the broader incident to HHS as affecting approximately 320,702 people, the settlement class is limited to approximately 58,309 individuals who received breach notification letters.
