Person outside bus injured in clsn w hv veh in traf, sequela

This code signifies a long-term health condition or complication arising from an individual being injured while outside of a bus, specifically when that bus was involved in a collision with another heavy transport vehicle or bus in a traffic accident. It indicates that the initial injury has led to a lasting consequence requiring ongoing medical attention or management.

This code is appropriate for documenting sequelae (e.g., chronic pain, permanent disability, scar contractures, psychological trauma) that are directly attributable to an injury sustained in the described accident. It should be used when the acute phase of the injury has passed, and the patient is presenting for treatment or evaluation of these persistent effects.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, fracture nonunion).
• Ensure documentation clearly links the current condition to the past external cause event described by this code.
• This "S" seventh character indicates sequela and should only be used for conditions that are residual effects of a past injury.
