In what situation may a covered entity disclose PHI without authorization?

The option regarding public health activities is correct because federal laws, specifically the Health Insurance Portability and Accountability Act (HIPAA), allow covered entities to disclose Protected Health Information (PHI) without patient authorization for specific public health purposes. Such purposes include reporting diseases or injuries to public health authorities, preventing or controlling disease, or addressing vital statistics like births and deaths. These disclosures are essential for protecting public health and safety, enabling health departments and other agencies to respond effectively to health-related issues.

In contrast, disclosing PHI for marketing purposes typically requires patient authorization, as marketing activities can potentially exploit sensitive information for commercial gain. The choice mentioning all disclosed data regardless of location is overly broad and does not align with the specific guidelines that regulate PHI disclosures. Regarding research without regulatory oversight, HIPAA generally necessitates certain protections and oversight to ensure patient privacy is maintained unless specifically waived under stringent conditions. Therefore, the allowance for public health disclosures is a crucial exception to the general rule that requires patient consent, aimed at safeguarding community health interests.
