‘Chicago Med’ Officially Makes a Massive Change for Season 12

Chicago Med and the rest of the shows in the One Chicago universe return on October 7, so we’re officially less than a month out. Each season brings some new changes, but Chicago Med Season 12 remains relatively untouched. All the series regulars will return, and so will the showrunner and some recurring guest stars. There have been no episode reductions this season, so viewers can enjoy the full range of storylines without worrying that some will be left behind. But when the season kicks off next month, some time will have passed in the ED.
