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

This code describes a patient who was a passenger in a large commercial vehicle (e.g., truck, bus) and sustained injuries from a subsequent encounter related to a traffic accident where that vehicle collided with another large commercial vehicle or bus. The "subsequent encounter" indicates that 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 collision with another heavy transport vehicle or bus. This applies to situations where the initial injury has already been treated and the patient is now receiving continued care.

• Ensure the documentation clearly specifies the patient's role as a passenger and the type of vehicles involved in the collision.
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the injury.
• Always code the specific injury(ies) sustained in addition to this external cause code.
