    • If other, please specify: MCG Health, LLC (“MCG”) is a HIPAA business associate that provides patient care guidelines to health care providers and health plans. MCG determined on March 25, 2022 that an unauthorized party previously obtained certain personal information of its customers’ patients and members that matched data stored on MCG’s systems. The affected patient or member data included some or all of the following data elements: names, Social Security numbers, medical codes, postal addresses, telephone numbers, email addresses, dates of birth and gender. Upon learning of the issue, MCG took steps to understand its nature and scope and to secure the company’s systems. A leading forensic investigation firm was retained to assist in the investigation, and MCG is coordinating with the FBI. Additionally, MCG has deployed additional monitoring tools and continues to enhance the security of its systems. Based on a third-party analysis of the data, there is evidence to suggest the data may have been acquired by an unauthorized party on or around February 25-26, 2020. Because there is uncertainty regarding the date the breach occurred, however, MCG has populated the mandatory field above regarding the breach date with the date MCG discovered the breach. MCG is providing notice of this incident on behalf of the customers identified in Exhibit A at their request. MCG is notifying approximately 17 affected Maine residents on behalf of these customers. MCG has arranged to offer these individuals identity protection and credit monitoring services through Experian for two years at no cost to them.
