Which of the following is NOT a valid method for transmitting PHI?

The option identifying sending a text message as not a valid method for transmitting Protected Health Information (PHI) is correct due to the inherent security risks associated with standard text messaging. Text messages are often transmitted over unsecured networks and do not have adequate encryption protocols in place to protect sensitive information. Therefore, using text messages for transmitting PHI does not comply with HIPAA regulations, which require the implementation of safeguards to ensure the confidentiality and integrity of such information.

In contrast, utilizing secure online portals, faxing documents to authorized recipients, and using encrypted emails are considered valid methods for transmitting PHI, as they offer more robust security measures. Secure online portals typically have safeguards like encryption and secure access controls designed to protect health information. Faxing to authorized recipients is acceptable when both the sender and receiver have taken appropriate measures to ensure that the transmission is secure. Encrypted emails protect the content of the messages during transmission, aligning with regulatory requirements to safeguard PHI.
