Acute epiglottitis without obstruction

This code signifies an acute inflammatory process of the epiglottis, a cartilage flap at the base of the tongue, without any evidence of airway obstruction. It represents a sudden onset of epiglottic swelling and inflammation, often bacterial in origin.

Assign this code when documentation clearly indicates acute epiglottitis and explicitly states the absence of airway obstruction. This is typically supported by clinical examination findings, such as visualization of an inflamed epiglottis, and the patient's stable respiratory status.

• Do not use this code if any degree of airway obstruction is documented; a different code specifying obstruction would be more appropriate.
• Always review the physician's notes for specific mention of "without obstruction" or similar phrasing to ensure accurate coding.
• Consider sequencing this code with an additional code for the underlying infectious agent, if identified and documented.
