Patient Portal Messages vs. Direct Secure Messaging: The patient portal and PCC EHR support two different messaging technologies. Portal messages are a secure, optional messaging tool built into the patient portal. Patient portal users can exchange messages with their pediatric practice, and the practice can receive and send portal messages with PCC EHR or pocketPCC. Direct Secure Messaging, on the other hand, is a specialized message technology used to share and send medical information. It requires registration with a third-party service and it allows for secure transmission of C-CDA transition of care documents or visit summaries. For more information, refer to Receive and Respond to Portal Messages or Direct Secure Messaging.
