Laryngeal diphtheria

This code represents diphtheria specifically affecting the larynx, characterized by the formation of a pseudomembrane in the throat that can lead to airway obstruction. It is a severe bacterial infection caused by Corynebacterium diphtheriae, primarily impacting the upper respiratory tract.

Use this code when documentation explicitly states laryngeal diphtheria, often presenting with hoarseness, stridor, and potential respiratory distress. Confirmation typically involves bacterial culture from the pseudomembrane or clinical diagnosis based on characteristic symptoms in an unvaccinated individual.

• Differentiate from other forms of diphtheria (e.g., pharyngeal, cutaneous) which have distinct codes.
• Always look for documentation of the specific anatomical site of diphtheria involvement.
• Consider sequencing with codes for respiratory failure or tracheostomy if present due to airway obstruction.
