Food in resp tract, part unsp causing asphyxiation, subs

This code indicates a patient presenting for follow-up care related to a previous episode of asphyxiation caused by food lodged in an unspecified part of the respiratory tract. The initial event involved a foreign body airway obstruction due to food, leading to a lack of oxygen.

Use this code for any encounter after the initial treatment of asphyxiation due to food in the respiratory tract, where the specific location of the food was not documented. This includes follow-up appointments for monitoring, managing complications, or addressing residual symptoms from the initial aspiration event.

• Requires a seventh character of "D" for subsequent encounter.
• Ensure documentation clearly states "food" as the foreign body and "asphyxiation" as the outcome.
• If the specific location of the food in the respiratory tract is known, a more specific T17 code should be used.
