Gastric contents in trachea causing other injury, sequela

This code signifies a long-term or residual effect resulting from the aspiration of gastric contents into the trachea, leading to a past injury. It indicates that the initial acute event has resolved, but the patient continues to experience a lasting consequence directly attributable to that aspiration.

Use this code when documenting a patient presenting with a chronic condition or complication that is a direct sequela of a previous aspiration of gastric contents into the trachea. This applies to situations where the initial aspiration event is no longer acute but has left a permanent or long-term impact on the patient's health.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic aspiration pneumonia, tracheal stenosis).
• Ensure documentation clearly links the current condition to a past aspiration event of gastric contents.
• This "S" code indicates a sequela and should be used for complications or conditions that arise as a direct result of a previous injury.
