Person on outside of amblnc/fire eng injured nontraf, subs

This code describes an injury sustained by an individual who was positioned on the exterior of an ambulance or fire engine, and the incident was not related to a traffic collision. This typically involves falls or impacts occurring during non-vehicular movement or stationary operations of the emergency vehicle. The "XD" suffix indicates this is for a subsequent encounter, meaning the patient is receiving follow-up care for an injury initially treated elsewhere.

Use this code for follow-up visits, such as wound care, physical therapy, or re-evaluation of an injury, for a person who was hurt while on the outside of an emergency vehicle (ambulance or fire engine) in a non-traffic accident. Examples include a firefighter falling off the side of a fire truck while it was parked at a scene, or an EMT being struck by an object while standing on the running board of an ambulance during a non-traffic incident.

• Ensure the accident explicitly did not involve a collision with another vehicle or object while the emergency vehicle was in motion on a public thoroughfare.
• Verify the patient was physically located on the exterior of the ambulance or fire engine at the time of injury.
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
