ER Wait Times in Wisconsin: 117 Hospitals Compared
117 hospitals in Wisconsin report how long their emergency room patients stay. The middle value here is 136 minutes; national (Medicare): 162 minutes.
What this time means
Each hospital’s number is Medicare measure OP-18b: the median (middle) time from arriving at the emergency room to leaving it, for patients who were treated and went home. Half of these patients left sooner, half later. It is not the time before seeing a doctor, and it leaves out patients who were admitted to the hospital, transferred, or seen for mental health.
Medicare’s name for the measure: “Average (median) time patients spent in the emergency department before leaving from the visit, excluding patients transferred to another facility or psychiatric care/mental health patients. A lower number of minutes is better”. Patients seen October 2024 to September 2025.
Emergency rooms in Wisconsin, shortest time first
Ranked by Medicare's median time (OP-18b), shortest first; hospitals with the same time share a rank. Left without being seen: share of ER patients who left before a doctor or nurse saw them (January 2024 to December 2024; national 2%). ER volume: patients per year, as Medicare groups it.

ER wait times by city in Wisconsin
Common questions
Which ER in Wisconsin has the shortest wait?
In Medicare's data for October 2024 to September 2025, Edgerton Hospital and Health Services had the shortest median time patients spent in the emergency room before going home: 71 minutes. This is the total time of the visit, not the time before seeing a doctor, and it is an average of past patients, not a promise for your visit.
What is the average ER wait time in Wisconsin?
The middle value of the 117 hospitals listed here is 136 minutes. The national figure published by Medicare is 162 minutes. Each hospital's number is the median time from arriving at the emergency room to leaving it, for patients who were treated and went home.
Should I drive to a farther ER to wait less?
No. In an emergency, call 911 or go to the nearest emergency room. These times are past averages; emergency rooms see the sickest patients first, and minutes lost on the road can matter more than minutes in a waiting room.
Does a shorter time mean a better emergency room?
Not by itself. Busier emergency rooms and hospitals that treat more serious cases usually have longer times, so the ER volume is shown next to each time. The time is one measure among many on each hospital’s page.
