Final answer:
The Department of Health and Human Services maintains a breach notification list as part of enforcing HIPAA's confidentiality and security protections for healthcare information.
Step-by-step explanation:
A breach notification list is a tool used to inform the public and applicable government bodies about incidents where protected health information (PHI) has been disclosed without authorization. In the United States, the Department of Health and Human Services (HHS) is responsible for maintaining such a list, specifically through its Office for Civil Rights (OCR). This action is part of HHS's commitment to enforcing the standards set by the Health Insurance Portability and Accountability Act (HIPAA), designed to protect the confidentiality and security of healthcare information.
