Mass General Brigham Health Plan, the covered entity (CE), reported that an employee impermissibly shared her system credentials with an unauthorized individual in an effort to outsource her job duties. This breach affected the protected health information (PHI) of 3,659 individuals. The PHI involved included names, addresses, medical record numbers, dates of birth, email addresses, phone numbers, Social Security numbers, health insurance and claims information, and diagnoses. The CE notified HHS, affected individuals, the media, and posted substitute notice on its website. In its mitigation efforts, the CE provided complimentary credit monitoring services and established a call center for questions or concerns. In addition, the employee was sanctioned and all staff were retrained on the requirement to protect and secure sensitive data.
