According to Distractify, Dr. Hannah Asher left “Chicago Med” during Season 6 and moved to Los Angeles to work on herself and overcome her heroin addiction. The show’s producers didn’t give a clear reason for the character’s departure, but many fans could assume it was simply because her story arc had finished. This has happened with other “Chicago Med” characters who have been removed from the drama as part of a “creative decision.” In other words, some characters, like Hannah, may not fit the current storyline the writers and producers have in mind.
And considering “Chicago Med” focuses on the lives of medical professionals working in a hospital, it makes sense that Hannah’s character, who clearly needed treatment for her addiction, could no longer work in the show’s fictional Gaffney Chicago Medical Center. This left little room for her in the “One Chicago” universe. Her leaving the show also gave Dr. Will Halstead a chance to mingle with other potential love interests after breaking up with Hannah.
Despite some practical reasons for her character’s demise, it turns out that “Chicago Med” isn’t done yet with Hannah.
