Passenger of 3- or 4- wheeled ATV injured nontraf, sequela

This code signifies a long-term health condition or complication resulting from an injury sustained by a passenger in a non-traffic accident involving a 3- or 4-wheeled all-terrain vehicle (ATV). The initial injury event occurred in the past, and the patient is now presenting with a residual effect directly attributable to that ATV accident.

Use this code when documenting a sequela, such as chronic pain, scar tissue, limited range of motion, or neurological deficits, that developed as a direct consequence of an ATV accident where the patient was a passenger and the incident did not occur on a public roadway. This code is appropriate for follow-up encounters addressing these persistent conditions.

• Always sequence the code for the specific sequela (e.g., chronic pain, fracture nonunion) first, followed by this external cause code.
• Ensure documentation clearly links the current condition to the past ATV accident and specifies the patient's role as a passenger.
• Verify the accident occurred off-road or in a non-traffic setting; otherwise, a different external cause code would be appropriate.
