Oth foreign object in pharynx causing asphyxiation, subs

This code signifies a patient presenting for follow-up care related to a previous episode of asphyxiation caused by a foreign object, other than food, lodged in the pharynx. The initial event involved a non-food item obstructing the airway at the pharyngeal level, leading to a lack of oxygen.

Use this code for subsequent encounters when a patient returns for evaluation of complications, ongoing symptoms, or recovery from an asphyxiation event due to a non-food foreign body in the pharynx. This includes visits for respiratory issues, dysphagia, or other sequelae after the initial treatment of the obstruction.

• Ensure the encounter is for follow-up care, not the initial treatment of the foreign body.
• Verify the foreign object was not food and was located in the pharynx.
• Confirm the "D" seventh character for subsequent encounter is appropriate.
