The show was renewed for a third season by the NBC on May 10, 2017.
Season 3 of Chicago Med will either premiere in November 17, 2017 or after the Holiday Break on January 9, 2018. It is more likely to be in January 2018. The reason for the delay is that Law and Order: True Crime: The Menendez Murders, a new show by NBC, will premiere on September 26, 2017 and will run in the new Med time slot and Med will resume afterward. This may also shorten the season to 15 episodes. However NBC has not confirmed details regarding the no. of epsiodes or the primere date yet.
