Web of larynx

This code describes a congenital malformation characterized by a membranous or fibrous obstruction within the laryngeal lumen. This web can partially or completely block the airway, leading to varying degrees of respiratory distress and voice abnormalities. It is typically located at the level of the vocal folds.

Use this code for documented cases of congenital laryngeal web, regardless of its severity or the presence of associated symptoms. Documentation should clearly identify the presence of a web within the larynx, often noted during laryngoscopy or other imaging studies. This code is appropriate for initial diagnosis and subsequent encounters related to the management of the laryngeal web.

• Differentiate from acquired laryngeal stenosis or scarring, which would be coded differently.
• Consider additional codes for associated symptoms like stridor (R06.1) or dysphonia (R49.0) if documented.
• Ensure the documentation specifies "congenital" to support the use of this Q code.
