However, the show utilizes real hospitals for location shots and exterior shots. They've filmed at various hospitals in Seattle, the city where the show is set, as well as in Los Angeles for some scenes.

While the show's interiors are fictional sets, they try to create a realistic atmosphere and have even consulted with real doctors and nurses for accuracy.
