Occupant (driver) of hv veh injured in unsp nontraf, subs

This code describes an individual, either the driver or a passenger, who sustained an injury while in a heavy transport vehicle (e.g., bus, truck, train) due to an accident that did not occur on a public roadway. This specific code is for a subsequent encounter, meaning the patient is receiving follow-up care for an injury that happened previously.

Use this code for patients presenting for ongoing treatment, rehabilitation, or evaluation of complications related to an injury sustained in a non-traffic incident involving a heavy transport vehicle. Examples include injuries from a fall within a bus in a depot, a train derailing on private property, or a truck accident on a construction site.

• Ensure the accident explicitly occurred in a non-traffic setting and involved a heavy transport vehicle.
• Confirm this is a subsequent encounter for the injury, not the initial treatment.
• Always code the specific injury first, followed by this external cause code.
