Pasngr in 3-whl mv inj in clsn w 2/3-whl mv nontraf, sequela

This code signifies an injury sustained by a passenger in a three-wheeled motor vehicle involved in a collision with another two- or three-wheeled vehicle. The accident occurred in a non-traffic area, such as a private road, parking lot, or farm. The "S" suffix indicates that this code is for the sequela, meaning a late effect or complication of the initial injury.

This code is appropriate when documenting a long-term consequence or residual condition directly resulting from such an accident. Examples include chronic pain, permanent disability, or scarring that is being treated months or years after the initial incident. It should be used in conjunction with a code describing the specific sequela.

• Always assign a code for the specific sequela (e.g., chronic pain, scar, malunion) first, followed by this external cause code.
• Ensure the documentation clearly states the patient was a passenger in a three-wheeled vehicle and the collision involved another two- or three-wheeled vehicle in a non-traffic setting.
• Verify that the encounter is for the treatment of a late effect, not the initial injury or subsequent acute care.
