2025 ICD-10-CM code T17.990

Foreign object in respiratory tract causing asphyxiation, part unspecified.

Use additional code (W44.-) for foreign body entering into or through a natural orifice, if known. Use additional code (Z18.-) to identify any retained foreign body, if applicable. Do not use additional external cause codes from Chapter 20.

In simple words: A foreign object entered the respiratory tract, causing difficulty breathing, but the specific location within the respiratory system is unknown.

Other foreign object in respiratory tract, part unspecified in causing asphyxiation.

Example 1: A child aspirates a small toy and experiences asphyxiation. The exact location of the toy within the respiratory tract is not identified through imaging., An adult chokes on food, leading to asphyxiation. The food particle causing the obstruction is not visualized during the event., An individual inhales an insect, leading to asphyxiation. The location of the insect in the respiratory tract is not determined.

Documentation should clearly state the asphyxiation event and the foreign body involvement. Details of the object, if known, and any resulting complications should be recorded.

** This code specifically refers to asphyxiation caused by a foreign body. It should not be used for mucus plugs unless they are causing asphyxiation. This code is only for when the exact part of the respiratory tract involved is not specified.
