Netflix Confirms Simultaneous Production of The Trauma Code Seasons 2 and 3

Netflix has officially confirmed that The Trauma Code: Heroes on Call will return for both Season 2 and Season 3, with the two seasons set to be produced simultaneously. The announcement was made on October 19, 2026, alongside confirmation of the returning cast and a new addition to the medical drama.

Starring Ju Ji-hoon, Choo Young-woo, Yoon Kyung-ho, and Jeong Jae-kwang, the series will continue following a trauma team fighting to save patients in critical condition. Actress and former Lovelyz member Jeong Yein will also join the cast as veteran nurse Cheon Jang-mi, taking over the role previously played by Ha Young.

The Trauma Code Returns for Two More Seasons

Originally released in 2025, The Trauma Code: Heroes on Call follows Baek Kang-hyuk, a brilliant trauma surgeon with battlefield experience who joins a struggling severe trauma care team and works to transform it.

The series attracted an international audience with its fast-paced medical emergencies, dramatic rescue sequences, and the chemistry among the hospital team. According to Netflix's announcement, the show appeared in the Top 10 lists of 63 countries.

The confirmation of two seasons at once marks a significant next step for the series. Netflix has also promised an expanded scale and new challenges for the characters as the story continues.

What to Expect from Season 2

Season 2 will follow Baek Kang-hyuk and the severe trauma team as they confront larger disasters and unpredictable crises.

According to Netflix, the new season will focus on the team's efforts to overcome systemic obstacles and protect the critical “golden hour” — the limited period in which urgent medical treatment can make a decisive difference to a patient's survival.

The story will continue exploring the team's work under pressure, their professional growth, and the challenges of delivering emergency care within a strained medical system.

Director Lee Do-yoon will write Season 2. Netflix has not yet announced a release date for the upcoming season.

Season 3 Will Have a New Writing Collaboration

Director Lee Do-yoon will also direct Season 3, working alongside new writer Tomasi on the script.

While Netflix has confirmed that Seasons 2 and 3 will be produced simultaneously, detailed plot summaries for Season 3 have not yet been released. Further information about its story and how it will develop beyond Season 2 is expected through future announcements.

The Main Cast Returns

The central cast will reunite for the upcoming seasons:

• Ju Ji-hoon as Baek Kang-hyuk, the gifted trauma surgeon leading the team.
• Choo Young-woo as Yang Jae-won, Baek Kang-hyuk's protégé and emerging successor.
• Yoon Kyung-ho as Han Yu-rim, who is promoted to chief of planning and coordination at Hankuk National University Hospital.
• Jeong Jae-kwang as Park Gyeong-won, the anesthesiologist who contributes to the team's work.

Their return means the series will continue building on the relationships and teamwork established in its first season.

Jeong Yein Joins as Nurse Cheon Jang-mi

One of the major casting updates is the addition of Jeong Yein, known as a member of the K-pop girl group Lovelyz and for her entertainment and acting work.

She will play Cheon Jang-mi, the veteran nurse previously portrayed by Ha Young in Season 1. Ha Young has stepped down from the project, and Jeong Yein was selected for the role following an audition process.

The character remains part of the severe trauma team's story, and viewers will see Jeong Yein take on the role as the series moves into its next chapters.

Netflix has indicated that filming will begin soon. Viewers should follow official Netflix announcements for updates on production, trailers, and release schedules.

Final Thoughts

The confirmation of simultaneous production for Seasons 2 and 3 gives The Trauma Code: Heroes on Call a substantial continuation, with its core cast returning and Jeong Yein joining as nurse Cheon Jang-mi.

Season 2 will raise the stakes with larger disasters and new challenges for the trauma team, while the details of Season 3 remain under wraps. Although the premiere dates are still unconfirmed, fans can look forward to the return of Baek Kang-hyuk and his team in the next chapters of this popular Korean medical drama.
