Web of larynx

This code describes a congenital malformation of the larynx characterized by a membranous obstruction or fusion of the vocal cords or subglottic region. This web can partially or completely block the airway, leading to varying degrees of respiratory distress and voice abnormalities. The severity depends on the thickness and extent of the web.

Use this code when documentation clearly indicates a congenital laryngeal web as the primary diagnosis. This typically presents in neonates or infants with stridor, hoarseness, or difficulty breathing. Supporting documentation would include direct laryngoscopy findings, bronchoscopy reports, or imaging studies confirming the presence and location of the web.

• Differentiate from acquired laryngeal stenosis or scarring, which would be coded differently.
• Specify any associated congenital anomalies if documented, using additional codes.
• Ensure the documentation clearly states "congenital" to support this specific code.
