The Trauma Code: Heroes on Call is an eight-episode Korean medical drama about a combat-experienced surgeon who arrives at a Seoul hospital determined to build a top-tier trauma center. Ju Ji-hoon leads the rescue-and-teamwork story as Baek Kang-hyuk, whose plans bring him into conflict with hospital leadership. It is fictional entertainment, not a documentary or a guide to emergency medicine.

Rescue sequences and high-pressure cases sit alongside team camaraderie, humor, and hospital politics. The drama’s appeal is not limited to medical crises: it also follows the relationships and disagreements that shape the team, and Baek’s effort to change how the hospital responds to trauma.
Netflix describes the series as witty, inspiring, and a medical drama. Its emergency scenes are dramatized for television; the series should not be treated as a documentary account of Korean trauma care or as medical instruction.

Who’s in the cast of The Trauma Code: Heroes on Call?
| Actor | Character | Role in the story |
|---|---|---|
| Ju Ji-hoon | Baek Kang-hyuk | The trauma surgeon leading the effort to build the center. |

What kind of medical drama is it?
The series balances action and workplace drama. Viewers looking for rescue-driven momentum will find urgent calls and high-stakes situations; those more interested in an ensemble will find the team’s development and its friction with hospital leadership. Humor and camaraderie soften the intensity, while the central medical crises keep the stakes high.

Is The Trauma Code: Heroes on Call based on a book?
It is adapted from the webtoon Trauma Center: Golden Hour by Hansanleega and Hongbichira. The adaptation is established; a physical print edition is not established by the sources cited here, so the webtoon is the confirmed starting point for readers interested in the story’s origin.
When did it come out, and where can you watch it?
The Trauma Code: Heroes on Call premiered on Netflix on January 24, 2025. Netflix lists it as a Korean series with eight episodes. It is available as a Netflix title, but whether it can be watched, and which audio or subtitle options are offered, depends on the viewer’s market and Netflix’s current local catalog.

WEBTOON Entertainment reported that the series spent four weeks in Netflix’s Top 10 Non-English Series list after its January 2025 debut. That statement describes the length of time on the list; it is not a viewer count or an all-time ranking.
Netflix’s release announcement says, “While the series embraces the drama of fiction, its attention to medical detail ensures an authentic viewing experience.” That is promotional language from Netflix, not independent verification of the show’s medical accuracy. The series is best approached as a medical drama rather than a factual account of clinical practice.
