Person outside 3- or 4- wheeled ATV injured nontraf, sequela

This code signifies a long-term complication or condition resulting from an injury sustained by an individual who was outside of a 3- or 4-wheeled all-terrain vehicle (ATV) during a non-traffic accident. The initial injury occurred in an off-road setting, and the patient is now presenting with a residual effect of that past event.

Use this code when documenting a sequela, such as chronic pain, scar tissue, limited range of motion, or neurological deficits, directly attributable to a previous ATV accident where the patient was not an occupant. This applies to individuals who were, for example, bystanders, pedestrians, or working near the ATV when the non-traffic incident occurred.

• Requires a seventh character of 'S' to indicate sequela.
• Always code the nature of the sequela first, followed by this external cause code.
• Ensure the documentation clearly links the current condition to the past ATV non-traffic accident.
