T17.3 Foreign body in larynx

Name of the Condition

• Foreign body in larynx
• Medical Code: T17.3

Summary

This condition involves the presence of a foreign object lodged in the larynx (voice box). It can cause airway obstruction, injury, or irritation, depending on the object's size, shape, and location.

Causes

Foreign bodies in the larynx typically result from accidental aspiration or inhalation of objects such as food particles, small toys, or other items. Intentional insertion is less common but may occur, especially in children.

Risk Factors

• Children, especially toddlers, due to oral exploration.
• Elderly individuals or those with neurological disorders impairing swallowing or cough reflexes.
• Eating habits like talking or laughing while eating.
• Activities involving small objects near the mouth.

Symptoms

• Sudden respiratory distress, coughing, or gagging.
• Hoarse voice or difficulty speaking.
• Stridor (high-pitched wheezing sound).
• Possible cyanosis (bluish discoloration from lack of oxygen).

Diagnosis

Diagnosis involves a physical examination and patient history to assess symptoms and potential exposure. Imaging studies like X-rays or CT scans may locate the object, while flexible laryngoscopy allows direct visualization of the larynx.

Treatment Options

• Immediate removal of the foreign body via laryngoscopy or bronchoscopy.
• In severe cases, a tracheostomy may secure the airway.
• Antibiotics if infection risk exists from tissue damage.

Prognosis and Follow-Up

Prognosis depends on the object's size, location, and time to removal. Early intervention usually leads to full recovery. Follow-up may include monitoring for airway stability or vocal cord function.

Complications

• Airway obstruction or respiratory failure.
• Laryngeal edema or infection.
• Vocal cord injury or scarring.
• Chronic cough or voice changes.

Lifestyle & Prevention

• Supervise young children during eating or play.
• Avoid talking or laughing while eating.
• Keep small objects out of reach of children.
• Use proper safety measures during activities with debris.

When to Seek Professional Help

Seek immediate medical attention if experiencing sudden choking, difficulty breathing, stridor, or cyanosis. Prompt evaluation is critical to prevent airway compromise.

Tips for Medical Coders

Document the type of foreign body (if known), location, and any associated injury or complications. Ensure the encounter type (e.g., initial, subsequent) is specified if applicable. Code T17.3 is used for foreign bodies in the larynx without additional injury; specify laterality or other details if documented.
