The physicians at Digestive Healthcare of Georgia are closely monitoring the coronavirus (COVID-19) outbreak. In the interest of everyone’s health and safety we ask all patients and their guests who have a fever (100° or above), symptoms of a respiratory infection, or who may have traveled to a restricted country or may have been exposed to a person with known COVID-19, the flu or any other communicable disease to reschedule their appointments or procedures. You will not be charged for canceling/rescheduling your appointment. We will be following CDC and Georgia Department of Public Health’s recommendations for screening and management of patients. If you are at all concerned you may have a serious infectious disease, your best course of action is to seek care at your primary care physician’s office or local hospital’s emergency department.

We have implemented a telemedicine visit for our patients who are unable to be in the office for their appointment. Please call our office to schedule a telemedicine visit with your provider.
