Pasngr on bus injured in clsn w nonmtr vehicle in traf, subs

This code indicates that a patient, who was a passenger on a bus, sustained injuries from a traffic accident involving a collision with another nonmotor vehicle (e.g., bicycle, animal-drawn vehicle). The "D" suffix signifies that this is a subsequent encounter, meaning the patient is receiving follow-up care for injuries initially treated in a previous encounter.

This code is appropriate for documenting ongoing treatment, such as physical therapy, wound care, or follow-up appointments, for injuries sustained by a bus passenger in the described type of traffic accident. It should be used after the initial acute care for the injuries has been provided and coded with the appropriate initial encounter (A) code.

• Ensure the patient was a passenger on a bus and the collision involved a nonmotor vehicle.
• Verify that this is a subsequent encounter for the injury; do not use for initial treatment.
• Always code the specific nature of the injury(ies) first, followed by this external cause code.
