Food in pharynx causing asphyxiation, initial encounter

This diagnosis code signifies an acute event where food lodged in the pharynx leads to a life-threatening obstruction of the airway, resulting in asphyxiation. It indicates the patient is presenting for the initial treatment of this specific choking incident.

This code is appropriate for emergency department visits or initial hospital admissions where a patient presents with symptoms of choking on food, requiring immediate intervention due to airway compromise. It should be used when the primary cause of asphyxiation is clearly identified as food in the pharynx.

• Ensure documentation clearly specifies "food" as the foreign body causing the obstruction.
• Verify that the encounter is indeed the "initial encounter" for this specific choking episode.
• Consider additional codes for any resulting complications, such as anoxic brain injury or aspiration pneumonia.
