Passenger of amblnc/fire eng injured nontraf, sequela

This code signifies a long-term effect or complication resulting from an injury sustained by an individual who was a passenger in an ambulance or fire engine, where the incident did not involve a collision with another vehicle or a pedestrian. It indicates that the initial injury has resolved, but the patient is now presenting with a residual condition directly attributable to that past non-traffic accident.

Use this code when documenting a sequela (e.g., chronic pain, scar contracture, nerve damage) stemming from an injury sustained while a passenger in an emergency vehicle (ambulance or fire engine) during a non-traffic incident. This applies to situations like a sudden stop, equipment malfunction, or internal impact within the vehicle that caused injury, and the patient is now being treated for the lasting effects.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past non-traffic accident in the emergency vehicle.
• Verify that the "S" seventh character is appropriate, indicating a sequela, rather than an initial encounter or subsequent encounter for the original injury.
