Passenger on bus injured in clsn w unsp mv in traf, sequela

This code signifies a long-term health condition or complication arising from a past injury sustained by a passenger on a bus involved in a traffic collision with an unspecified motor vehicle. The initial injury has resolved, but its lasting effects are now being treated or evaluated.

Apply this code when a patient presents with a sequela (e.g., chronic pain, limited range of motion, neurological deficits) directly attributable to a previous bus accident where they were a passenger. This is appropriate for follow-up encounters addressing these persistent issues, not for the initial injury treatment.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past bus accident.
• Verify the "S" seventh character is appropriate for sequela, indicating the long-term effects of the initial injury.
