Unsp foreign body in larynx causing other injury, sequela

This code signifies a long-term or late effect resulting from an unspecified foreign object in the larynx that caused an injury other than obstruction or asphyxiation. The initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that foreign body event.

Apply this code when documentation clearly indicates a sequela from a past laryngeal foreign body injury, where the specific nature of the foreign body is unknown, and the resulting injury was not an airway obstruction or asphyxiation. This is appropriate for follow-up encounters addressing chronic issues stemming from such an event.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure the medical record explicitly links the current condition to a past laryngeal foreign body injury.
• Avoid using this code for acute foreign body encounters; those require codes from the initial encounter or subsequent encounter categories.
