Final answer:
The healthcare coordinator should access and update the patient's home address in the Demographics section of the electronic medical record (EMR) to maintain accurate information.
Step-by-step explanation:
In an electronic medical record (EMR), the area that the healthcare coordinator should access and update to maintain accurate information about a patient's new home address is the Demographics section.
This section typically includes personal information such as the patient's name, contact details, including their address, phone number, and email address, date of birth, gender, and other relevant demographic details.
Updating the patient's home address in the Demographics section ensures that the healthcare provider has the most up-to-date information and can easily reach out to the patient if needed.
