Food in larynx causing other injury, sequela

This code signifies a long-term or late-onset complication resulting from a past event where food lodged in the larynx caused an injury other than asphyxiation or obstruction. These sequelae can manifest as chronic inflammation, scarring, or other persistent issues in the laryngeal region.

This code is appropriate for documenting conditions that are a direct consequence of a previous laryngeal injury due to aspirated food, where the acute event has resolved but its lasting effects are still present. Examples include chronic dysphonia or recurrent aspiration pneumonia attributed to laryngeal damage from a past food aspiration incident.

• Requires a seventh character "S" to indicate sequela.
• Always link to an external cause code (V00-Y99) if known, to specify the circumstances of the original injury.
• Do not use for acute or current foreign body aspiration; this code is specifically for the residual effects.
