Netflix has confirmed it will make two more seasons of its Korean medical drama “The Trauma Code: Heroes on Call,” ending months of speculation about a sequel to one of its biggest non-English hits. The streamer announced Monday that Seasons 2 and 3 are in production together. Ju Ji-hoon returns as Baek Kang-hyuk, the battlefield-trained trauma surgeon who takes over a neglected trauma unit at a university hospital. Choo Young-woo, Yoon Kyung-ho and Jeong Jae-kwang also return. Jeong Ye-in joins as Cheon Jang-mi, a veteran nurse on the team, replacing Oh Ha-young, who left the project.
Director Lee Do-yoon, who led the first season, will helm both new installments and write Season 2. A new writer joins him for Season 3. Netflix says the story will push the team into larger disasters and more unpredictable crises, with Baek working to build a sturdier trauma care system. Studio N and Mays Entertainment produce the series, which adapts the webtoon “Trauma Center: Golden Hour.”
Netflix has not given a premiere window for either season. The announcement follows a year of mixed signals. Korean outlets reported in September 2025 that both seasons were set to shoot back-to-back, and a Netflix Korea representative answered that follow-ups were “under review” with nothing finalized. Monday’s statement resolves that question.
The first season, released Jan. 24, 2025, made Netflix’s Top 10 lists in 63 countries and took first place in 18. It climbed to No. 2 on the platform’s global rankings within days of launch, a run that briefly put it ahead of “Squid Game” Season 2. The source novel’s author, an otolaryngologist writing as Han San-i, has said the story was planned for multiple seasons from the outset.
Shooting two seasons at once has become a common approach for streamers protecting a hit. It holds a cast together, trims costs and shortens the wait between releases. For a show whose lead and supporting actors have other commitments, the arrangement also locks in schedules before they fill. Netflix has not detailed the number of episodes planned for each new season.
