TV's "Chicago ___"

MED

This medical drama spin-off focuses on the emergency department of Gaffney Chicago Medical Center and shares its universe with "Chicago Fire" and "Chicago P.D."

This clue refers to the medical drama series "Chicago Med", part of the Chicago franchise on NBC that also includes Chicago Fire and Chicago P.D. The blank in the clue hints at the shortened form of "medical," which is "med." Since the show’s full title is Chicago Med, the answer fits perfectly as the missing word.
