Overview

An Emergency Department visit is an unscheduled hospital-based evaluation for urgent health concerns. Low or moderate refers to the complexity of medical decision making documented by the clinician, not necessarily how you feel. Many people with low or moderate complexity visits are evaluated, treated, and discharged the same day. During the visit, a team reviews your symptoms, medical history, and vital signs. They may order tests, provide medicines, perform minor procedures, or monitor you for a short time. The goal is to identify urgent problems, start treatment, and decide if you can safely go home or need further care.
