DENVER — Some of the victims fighting for their lives after being wounded in the movie-theater shooting rampage may face another challenge when they get out of the hospital: enormous medical bills without the benefit of health insurance.

Members of the public, along with Warner Bros., the studio that released the Batman movie “The Dark Knight Rises,” have contributed nearly $2 million to help victims, though it’s not clear how much of that will cover medical expenses. One family is raising money on its own online.

And three of the five hospitals treating victims said Wednesday they will limit or completely wipe out medical bills.

Nearly one in three Coloradans, or about 1.5 million, either have no health insurance or have coverage that is inadequate, according to a 2011 report by The Colorado Trust, a health care advocacy group.
