Final answer:
The medical assistant should always check with the provider about their preferences before setting up the appointment matrix.
Step-by-step explanation:
The statement in the question is false. Before setting up the appointment matrix, the medical assistant should always check with the provider about their preferences. This is important because different providers may have different scheduling preferences, availability, and requirements.
For example, some providers may prefer to have certain time slots blocked off for certain types of appointments or procedures. Others may have specific days or hours they are not available. By checking with the provider, the medical assistant can ensure that the appointment matrix is accurately set up to accommodate the provider's preferences and availability.
