Food in larynx causing asphyxiation, subsequent encounter

This code describes a situation where food lodged in the larynx has led to a life-threatening lack of oxygen, and the patient is presenting for follow-up care after the initial event. This indicates that the acute phase of asphyxiation has passed, but the patient is still under medical management related to the incident.

Apply this code for patients returning for subsequent evaluation or treatment related to a past episode of asphyxiation caused by food in the larynx. This includes visits for monitoring, management of complications, or follow-up after initial discharge. It should not be used for the initial encounter where the asphyxiation occurred.

• Ensure the documentation clearly states that this is a subsequent encounter for the specified condition.
• Confirm the foreign body was specifically food and located in the larynx, leading to asphyxiation.
• Do not use for initial treatment of the acute asphyxiation event.
