Unspecified transport accident, sequela

This code signifies a long-term or residual effect stemming from an unspecified transport accident. It indicates that the initial injury has healed, but the patient continues to experience a health problem directly attributable to that past event. The specific type of transport involved is not documented or known.

This code is appropriate when a patient presents with a sequela (e.g., chronic pain, scar contracture, neurological deficit) that is clearly linked to a previous transport accident, but the specific mode of transport (e.g., motor vehicle, pedestrian, bicycle) was never identified or documented. It should be used for follow-up encounters after the acute phase of the original injury has passed.

• Always sequence this sequela code after the code describing the specific residual condition.
• Ensure documentation clearly links the current condition to a past "unspecified transport accident."
• Avoid using this code if the specific type of transport accident is known and documented; use a more specific sequela code from the appropriate transport category.
