Chronic laryngotracheitis

This code represents a persistent inflammation of both the larynx (voice box) and trachea (windpipe). This condition is characterized by long-standing irritation, swelling, and potential narrowing of these upper airway structures, often leading to chronic cough, hoarseness, and difficulty breathing.

Use this code when documentation clearly indicates a chronic inflammatory process affecting both the larynx and trachea. This typically applies to conditions that have persisted for an extended period, often weeks or months, and are not acute in nature. Supporting documentation would include physician notes detailing chronic symptoms and diagnostic findings consistent with long-term inflammation.

• Differentiate from acute laryngotracheitis; the chronicity must be explicitly stated or clearly implied by the duration of symptoms.
• Consider additional codes for underlying causes (e.g., GERD, allergies) if documented.
• Ensure documentation specifies involvement of both the larynx and trachea; if only one is affected, a more specific code should be used.
