Which of the following is NOT a method to access appointment desk activity?

The statement that making a phone call to confirm appointments is not a method to access appointment desk activity is accurate because appointment desk activity typically refers to functionalities within the Epic system that facilitate the scheduling and management of appointments directly through the software interface.

Methods such as using the appointment desk icon in the registration toolbar or clicking the Epic button to select 'Scheduling' are directly related to navigating the Epic system itself. Similarly, looking up a patient after accessing the activity menu is another means of interacting with the scheduling functionalities that Epic offers. These options utilize the tools and features designed for appointment management.

In contrast, making a phone call is an external communication method that does not involve the Epic software's scheduling module directly. While confirming appointments via phone may be part of the overall scheduling process, it does not constitute accessing the appointment desk activity within the Epic system interface. Thus, this choice correctly identifies an option that does not match the criteria of accessing appointment-related functionalities directly through the software.
