CBS has given a Back 5 order to medical drama Code Black, bringing its freshman order to 18 episodes. It joins fellow new fall CBS series Limitless and Life In Pieces, both of which have received full-season orders for 22 episodes. No back-order decision yet on the latest CBS series to debut this season, Supergirl.

CBS Logo Featured 1After a modest debut, 1.5 in Live+Same Day 18-49, Code Black has been getting little attention. Its DVR lifts also have been modest, with the premiere inching up a tenth to a 1.6 in Live+3. But, flying under the radar, Code Black has been improving little by little, something very few shows have accomplished, with its Live+3 results for the first three weeks trending up: 1.6, 1.7, 1.8. That’s still a soft performance, but the upward trajectory was somewhat encouraging. In L+SD, Code Black has been steady in the Wednesday 10 PM slot, most recently logging a 1.2 in 18-49 for the past couple of airings, just .3 off the series premiere.

Based on the award-winning documentary by Ryan McGarry, Code Black takes place in the busiest, most notorious ER in the nation. Marcia Gay Harden, Bonnie Somerville, Melanie Kannokada, Benjamin Hollingsworth, Harry M. Ford, Luis Guzman, Raza Jaffrey and William Allen Young star. Michael Seitzman created the show and executive produces with Marti Noxon, Linda Goldstein-Knowlton, Ryan McGarry and David Semel for ABC Studios in association with CBS Television Studios.
