Food in trachea causing other injury, sequela

This code signifies a long-term or residual effect resulting from a past event where food entered the trachea, leading to an injury other than aspiration pneumonia or obstruction. It indicates that the initial tracheal injury caused by the food has resolved, but the patient continues to experience a related health problem.

Apply this code when documenting a current condition that is a direct consequence of a previous episode of food in the trachea causing injury. This would include scenarios where the initial injury has healed, but there are lasting complications or chronic issues attributable to that event.

• Requires a seventh character "S" to denote sequela, indicating a late effect.
• Always sequence this code after the code for the specific sequela or residual condition being treated.
• Do not use for acute events or when the food is still present in the trachea; those scenarios require acute injury codes.
