ICD-10 Code J34.829 – Nasal valve collapse, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.829 – Nasal valve collapse, unspecified
What it is
This code identifies collapse or narrowing of the nasal valve, the area that helps regulate airflow through the nose. “Unspecified” means the record does not document whether the internal or external valve is involved.
Clinical signs
Typical findings include nasal obstruction, difficulty breathing through the nose, and visible or reported nasal wall collapse with inspiration. Clinical features vary; refer to documentation.
When to use this code
Use J34.829 when the provider documents nasal valve collapse but does not specify a more precise type. It may apply in office, ENT, or preoperative evaluations when the diagnosis is stated clearly in the chart. Check documentation if the note only mentions general nasal congestion or obstruction.
Do not use for
Do not use this code for simple rhinitis, sinus congestion, or other causes of nasal blockage without documented valve collapse. If the record specifies a different nasal structural problem, code that condition instead.
Coding tip
Assign this code only when the provider explicitly documents nasal valve collapse and no further detail is available.
