ICD-10 Code J34.82 – Nasal valve collapse (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.82 – Nasal valve collapse
What it is
Nasal valve collapse is narrowing or inward collapse of the nasal airway at the valve area, which can obstruct airflow. It is a structural cause of nasal blockage and may be internal or external.
Clinical signs
Common findings include nasal obstruction, difficulty breathing through the nose, and visible collapse of the sidewall during inspiration. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents nasal valve collapse as the diagnosis or a confirmed cause of obstruction. It fits encounters for evaluation of chronic nasal blockage, especially when exam or specialist assessment identifies valve collapse. Code the documented condition, not a nonspecific complaint alone.
Do not use for
Do not use this code for general nasal congestion, allergic rhinitis, or septal deviation unless nasal valve collapse is specifically documented. Check documentation if the record only mentions obstruction without a defined structural cause.
Coding tip
Look for wording such as “internal nasal valve collapse” or “external nasal valve collapse” in the assessment before assigning J34.82.
