Occup of 3-whl mv inj in clsn w 2/3-whl mv in traf, sequela

This code signifies a long-term consequence or late effect stemming from an injury sustained by an unidentified occupant of a three-wheeled motor vehicle. The original injury occurred during a traffic accident involving another two- or three-wheeled motor vehicle. The "sequela" indicates that the current encounter addresses a condition directly resulting from that past accident.

This code is appropriate when a patient presents for treatment of a chronic condition, disability, or complication directly attributable to a past collision where they were an unspecified occupant of a three-wheeled motor vehicle involved with another two- or three-wheeled vehicle. This includes conditions like chronic pain, scar contractures, or neurological deficits that manifest after the initial injury has healed.

• Always sequence the code for the specific sequela (e.g., chronic pain, scar) first, followed by this external cause code.
• Ensure documentation clearly links the current condition to the past three-wheeled motor vehicle accident.
• Only use the "S" seventh character for sequela encounters, not for initial or subsequent active treatment of the original injury.
