Inhalation and ingestion of other object causing obstruction of respiratory tract or suffocation

This code signifies an accidental event where a foreign object, other than food, enters the respiratory tract, leading to obstruction or suffocation. This can occur through either inhalation (breathing in) or ingestion (swallowing) of the object. The resulting clinical picture involves compromised breathing due to the presence of the foreign body.

Use this code when documentation clearly indicates an accidental inhalation or ingestion of a non-food object that caused respiratory distress, choking, or suffocation. Examples include a child aspirating a small toy, an adult inhaling a dental appliance, or someone accidentally swallowing a non-food item that subsequently obstructs the airway. The medical record should specify the nature of the object and the resulting respiratory compromise.

• Always code the specific foreign body (e.g., W44.x) as a primary or secondary diagnosis, if known, in addition to this external cause code.
• Distinguish carefully from aspiration of food (E91.0) or gastric contents (E91.1).
• Ensure the documentation specifies "other object" and not food, gastric contents, or other specified substances.
