Acute laryngotracheitis

This code represents an acute inflammation of both the larynx and trachea, characterized by symptoms such as hoarseness, cough, and stridor. It indicates a sudden onset of inflammation affecting the voice box and windpipe, typically resolving within a short period.

Assign this code when documentation specifies acute inflammation of the larynx and trachea without mention of obstruction. It is appropriate for cases of viral or bacterial laryngotracheitis where the primary clinical presentation is inflammation rather than significant airway narrowing.

• Do not use this code if the documentation specifies acute obstructive laryngotracheitis; refer to the Excludes1 note.
• Ensure the "acute" nature of the condition is clearly documented to differentiate from chronic forms.
• Look for terms like "laryngotracheitis," "croup," or "tracheitis" in conjunction with "acute" or "sudden onset."
