Which exception restricts the manner or content of fulfilling a request to access eHI?

The correct choice is the Content and Manner exception. This exception specifically addresses how electronic health information (eHI) is provided in response to access requests. It emphasizes that the format or mode of access can be tailored based on particular contexts, preferences, or limitations surrounding the request. For instance, if a person requests access to their health information, the healthcare provider may determine the most appropriate way to fulfill that request, which could include specifying the format in which the information is delivered (such as paper, electronic, etc.) or the method of transmission (like secure email versus regular mail).

Understanding this exception is vital for ensuring compliance with health information regulations while still accommodating the rights of patients to access their health information. It strikes a balance between access to eHI and the practical considerations of fulfilling such requests responsibly and securely.
