Postprocedural subglottic stenosis

This code represents the narrowing of the airway below the vocal cords that develops as a complication following a medical or surgical procedure. This stenosis can impede airflow and manifest with symptoms such as stridor, dyspnea, or hoarseness, often requiring further intervention.

Use this code when documentation clearly indicates subglottic stenosis occurring as a direct consequence of a previous medical or surgical intervention, such as intubation, tracheostomy, or laryngeal surgery. The patient's medical record should specify the causal link between the procedure and the development of the stenosis.

• Always identify the specific procedure that led to the postprocedural subglottic stenosis.
• Distinguish from congenital or idiopathic subglottic stenosis, which are coded differently.
• Consider sequencing this code after the primary reason for the patient's encounter if the stenosis is being treated.
