A caller reports a construction worker fell approximately 35 feet. The patient is awake and breathing, with multiple fractures and serious bleeding. What is the correct determinant code?

• A. 18-B-2
• B. 17-D-1
• C. 20-A-2
• D. 15-C-3

Answer: (B)

The key idea here is how determinant codes capture both how the injury happened and the patient’s current condition to set the right level of response. This scenario describes a high-energy mechanism (a fall from a significant height) with serious physical injuries (multiple fractures and heavy bleeding), yet the patient is awake and breathing, so the airway is clear and breathing is present.

The determinant code that best fits this picture encodes severe trauma from a high-energy MOI while the patient remains responsive. It signals to responders that this is not a minor injury and that bleeding and fractures are present, but there is no current airway obstruction or unresponsiveness. That combination guides higher-priority dispatch and the appropriate trauma management steps.

The other determinant codes would correspond to scenarios such as lower-energy trauma, no significant bleeding or injury, or compromised airway/unresponsiveness, which do not match this patient’s situation as well as the high-mechanism, actively bleeding, multi-injury yet responsive profile does.
