Stenosis of larynx

This code represents a narrowing or constriction of the larynx, the voice box, which can impede airflow and affect vocalization. This stenosis can be congenital, acquired due to trauma, infection, intubation, or inflammatory conditions, and can range in severity from mild to life-threatening.

Use this code when documentation clearly indicates a diagnosis of laryngeal stenosis. This includes conditions such as subglottic stenosis, glottic stenosis, or supraglottic stenosis, regardless of etiology. Supporting documentation should specify the location and nature of the laryngeal narrowing.

• Specify the exact anatomical site of the stenosis (e.g., subglottic, glottic) if documented, as more specific codes may exist for certain locations.
• Code any underlying cause or associated conditions, such as intubation-related injury or granuloma, in addition to the stenosis.
• Differentiate from other laryngeal conditions like paralysis or edema, which have distinct codes.
