ICD-10 Code J34.8201 – Internal Nasal Valve Collapse, Static (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.8201 – Internal nasal valve collapse, static
What it is
This code identifies a static collapse of the internal nasal valve, the narrowest part of the nasal airway. It means the valve is structurally narrowed or unsupported, causing reduced airflow through the nose.
Clinical signs
Typical findings include chronic nasal obstruction, mouth breathing, and visible narrowing of the nasal valve area. Symptoms are often worse during quiet inspiration; clinical features vary, refer to documentation.
When to use this code
Use this code when documentation clearly states internal nasal valve collapse and specifies that it is static rather than dynamic. It may also apply when the provider describes structural nasal valve narrowing or collapse contributing to obstruction. Check documentation if the note only says nasal obstruction without a defined valve diagnosis.
Do not use for
Do not use this code for general nasal congestion, septal deviation alone, or unspecified nasal obstruction. If the record does not distinguish static collapse from another cause, check documentation.
Coding tip
Look for the words “static,” “internal nasal valve,” or “valve collapse” in the assessment before assigning J34.8201.
