ICD-10 Code J38.6 – Stenosis of larynx (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J38.6 – Stenosis of larynx
What it is
J38.6 identifies narrowing of the laryngeal airway. Use it when documentation states laryngeal stenosis, which may be congenital or acquired and can limit airflow through the voice box.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include stridor, hoarseness, dyspnea, or airway obstruction noted on laryngoscopy or other direct exam.
When to use this code
Use J38.6 when the provider documents stenosis of the larynx as the diagnosed condition. It fits encounters for evaluation, follow-up, or management of a narrowed laryngeal airway. Code it only when the record clearly identifies the larynx as the site; check documentation if the airway level is unclear.
Do not use for
Do not use this code for tracheal, subglottic, or pharyngeal stenosis unless the larynx is specifically documented. Avoid it when the note only describes nonspecific airway narrowing; check documentation.
Coding tip
Confirm the exact anatomic site before coding, because airway stenosis codes differ by location.
