The long-gestating medical offshoot of the Chicago Fire franchise is taking a big step toward NBC’s primetime. A planted spinoff for the project will air as an episode of mothership series Chicago Fire later this season. Like Chicago PD, I hear the new spinoff hails from Chicago Fire creators/executive producers Derek Haas and Michael Brandt, executive producer Matt Olmstead and executive producer Wolf, whose company Wolf Films produces Chicago Fire and Chicago PD with Universal TV.

NBC topper Bob Greenblatt spoke of the spinoff during the NBC executive session this morning. “Chicago Med is something that we’re just seeding into the system, seeing if there’s a show there that could eventually spin off into itself,” he said.

After the Chicago Fire/Chicago PD panel, Wolf confirmed that Chicago Med will be introduced as an “integrated episode” of Chicago Fire. “There will be an event that brings Chicago Med within Chicago Fire,” he said.

Chicago Med would bring the number of series in the Chicago Fire franchise to three. Wolf’s venerable Law & Order franchise (as well as CBS’ CSI) also have yielded three successful series each to date. (Each has attempted to expand to four shows. There were mixed results for Law & Order: Trial By Jury; we are yet to see how CSI No.4, Cyber, will do.)

Chicago Med is bringing a new wrinkle to what has already been a very competitive and overcrowded marketplace for medical dramas this development season, with almost a dozen projects sold at the broadcast networks.

The Dick Wolf-produced Chicago Med will certainly put extra pressure on NBC medical drama The Night Shift, which is getting a midseason berth after a solid summer run. The network also has a couple of medical drama scripts, at least one of which will likely go to pilot. I hear heating up is Jill Gordon/Brad Silberling’s Heart Matters, and the network also has the Eva Longoria-produced Critical. 

Elsewhere, CBS has an untitled project from Jason Katims and Sarah Watson and Code Black, based on Ryan McGarry’s feature documentary, both with put pilot commitments, as well as the Neal Baer-produced Windward Clinic, an adaptation of the South Korean medical drama Good Doctor with Daniel Dae Kim producing, a Larry Kaplow project produced by Halle Berry and Katie Jacobs; LFE, produced by Dan Jinks; and Austen’s Razor, centered on a character inspired by Arthur L. Caplan, an authority on bioethics, which has a production commitment.

ABC’s medical advocate drama project from David Marshall Grant, Sheldon Turner and Jennifer Klein also have put pilot commitments. ABC also has a drama from Amy Holden Jones with a significant penalty, and Cold Blood, from Janine Sherman Barrois and Aaron Kaplan.
