2025 ICD-10-CM code T17.8

Foreign body in other parts of respiratory tract. This includes foreign bodies in the bronchioles and lungs.

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

Medical necessity is established by the presence of a foreign body in the respiratory tract causing symptoms or posing a risk of complications. Intervention is required to alleviate symptoms, prevent infection, or address airway obstruction.

The clinician is responsible for identifying the location of the foreign body, determining the appropriate method for removal, managing any resulting respiratory complications, and providing follow-up care.

In simple words: This code indicates the presence of a foreign object in the smaller airways of the lungs, such as the bronchioles or lung tissue itself.

Foreign body lodged in parts of the respiratory tract other than the nasal sinuses, nostrils, pharynx, larynx, trachea, or bronchus.This includes foreign bodies in the bronchioles and lungs.

Example 1: A 3-year-old child aspirates a small toy piece into their lung. Bronchoscopy confirms its presence in the bronchioles., A patient inhales a peanut, which becomes lodged in the lung parenchyma.Imaging studies reveal the location of the foreign body and guide intervention., During a dental procedure, a small piece of dental equipment is dislodged and inhaled by the patient. The foreign body ends up in the lungs. Imaging techniques are used to localize the object to ensure appropriate retrieval.

Documentation should include details of the incident, symptoms, physical findings, imaging results (e.g. x-ray, CT scan), bronchoscopy findings (if performed), method of removal, and any complications.
