Supraglottitis, unspecified, without obstruction

This code describes inflammation of the supraglottic structures, including the epiglottis, aryepiglottic folds, and arytenoids, without specifying the causative agent. It indicates that there is no associated airway obstruction, which differentiates it from more severe presentations.

Use this code when documentation confirms supraglottitis but does not specify the infectious organism (e.g., bacterial, viral). It is appropriate for cases where the patient presents with symptoms like sore throat, dysphagia, or muffled voice, and examination reveals supraglottic inflammation without signs of respiratory distress or stridor.

• Do not use this code if the documentation specifies an infectious agent; instead, code to the specific organism.
• Ensure documentation explicitly states "without obstruction" to differentiate from codes indicating airway compromise.
• Consider sequencing this code as a primary diagnosis when supraglottitis is the main reason for the encounter.
