The Lyon Firm Files Class Action MCG Health Data Breach Lawsuit

UPDATE: The Lyon Firm has filed a class action complaint on behalf of plaintiffs that allege MCG Health failed to protect personal information that may lead to future identity theft and fraud. 

MCG Health, based out of Seattle, Washington, is a provider of patient care guidelines to healthcare providers and health plans. The company has started notifying patients and members of MCG that an unauthorized party may have obtained some of their protected health information.

According to the data breach notice on their website, MCG determined on May 25, 2022, that an unauthorized individual had obtained data that matched data on its systems. MCG Health has advised impacted individuals to review their account statements and monitor their credit reports for signs of misuse.

The breach notice does not explain the nature of the attack, though reports suggest about 1.1 million individuals could have their information compromised.

MCG Health Notification letters are being sent out to affected individuals. Compromised information may include the following:

  • Names
  • Genders
  • Emails
  • Addresses
  • Phone Numbers
  • Dates of birth
  • Drivers License numbers
  • Social Security numbers
