An ENT office visit for a new patient is a first-time visit with a doctor specializing in the diagnosis and treatment of disorders of the ear, nose, and throat. ENT is a branch of medicine and healthcare that deals with structures related to the ear, nose, and throat, including allergies, sinus complications, cyst removal, and more. A new patient office visit is needed if you have never seen this doctor and would be new to the practice, or it has been over 3 years since you last saw this doctor.
