Passenger in hv veh injured in clsn w unsp mv in traf, subs

This code describes a patient who was a passenger in a large vehicle (e.g., bus, truck) involved in a traffic accident with one or more motor vehicles that are not further specified. The "D" suffix indicates this is for a subsequent encounter, meaning the patient is receiving follow-up care for injuries sustained in the initial accident.

Use this code when documenting follow-up visits, rehabilitation, or ongoing treatment for injuries sustained by a passenger in a heavy transport vehicle involved in a multi-vehicle collision where the other vehicles are not precisely identified. This applies after the initial acute treatment phase.

• Ensure the patient was a passenger, not the driver, of the heavy transport vehicle.
• Confirm the encounter is for follow-up care related to the initial injury, not the initial treatment.
• Only use this code when the specific type of other motor vehicles involved in the collision is unknown or not documented.
