Unsp car occupant injured in clsn w hv veh nontraf, subs

This code signifies an injury sustained by an occupant of a car involved in a crash with a large commercial vehicle or bus, where the incident occurred off a public roadway. The specific type of injury is not documented, and this encounter represents follow-up care after the initial treatment.

Apply this code for subsequent visits related to an injury sustained by a car occupant in a non-traffic collision with a heavy transport vehicle or bus, such as an incident occurring in a parking lot, private driveway, or industrial site. This code is appropriate when the initial injury has been addressed, and the patient is returning for ongoing management, rehabilitation, or follow-up.

• Ensure the documentation clearly states the encounter is for subsequent care and not the initial treatment.
• Verify the collision occurred in a non-traffic setting (e.g., private property) and involved a heavy transport vehicle or bus.
• Always code the specific injury first, followed by this external cause code to provide context.
