Dental insurer and third-party administrator Managed Care of North America (MCNA) agreed to settle consolidated class action litigation stemming from a 2023 data breach affecting around 8.9 million individuals.

Assessment

The settlement resolves legal action arising from a confirmed breach of MCNA's network that exposed sensitive personal and health information on a large scale. While the breach itself dates to 2023, the settlement terms provide the concrete financial and remedial framework for affected class members, including attorney fees and costs, funded medical-data monitoring and reimbursement of documented losses.

Details

  • Records included names, contact details, dates of birth, Social Security or driver's licence or Medicare IDs, and dental-care information.
  • Under the settlement MCNA covers attorney fees up to US$6.4 million plus litigation costs up to US$1.31 million.
  • Class members receive two years of medical-data monitoring valued at around US$179 per year, plus reimbursement of documented unreimbursed losses up to US$2,500 per member.
  • The objection and opt-out deadline is 19 October 2026, with a final fairness hearing scheduled for 16 November.
