Occupant (driver) of hv veh injured in unsp traf, sequela

This code signifies a long-term consequence or complication arising from an unspecified traffic accident involving an occupant (driver or passenger) of a heavy transport vehicle. It indicates that the initial injury has healed, but residual effects or conditions persist, requiring ongoing medical attention or impacting the patient's quality of life.

Apply this code when documenting a sequela, such as chronic pain, permanent disability, or psychological trauma, directly attributable to a past traffic accident involving a heavy transport vehicle, where the specific nature of the accident was not initially documented or is unknown. This is appropriate for follow-up encounters addressing these persistent conditions.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, scar contracture).
• Ensure documentation clearly links the current condition to a past heavy transport vehicle traffic accident.
• The "S" in the 7th character indicates sequela; do not use for initial or subsequent encounters for the acute injury.
