ICD-10 Code J34.8211 – External nasal valve collapse, static (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.8211 – External nasal valve collapse, static
What it is
External nasal valve collapse, static, means the outer part of the nostril is narrowed or unsupported at rest. It can limit airflow through the nose even without obvious movement-related collapse.
Clinical signs
Patients may report chronic nasal obstruction, reduced airflow, or difficulty breathing through one or both nostrils. Clinical features vary; refer to documentation for exam findings such as visible narrowing or external valve weakness.
When to use this code
Use this code when the record clearly documents static collapse of the external nasal valve as the cause of nasal obstruction. It is appropriate for structural nasal airway problems described on exam, consultation, or operative documentation. Check documentation if the note only mentions congestion or unspecified obstruction.
Do not use for
Do not use this code for general nasal congestion, allergic rhinitis, or unspecified breathing complaints without documented external valve collapse. Check documentation if the condition is dynamic collapse only.
Coding tip
Code only when the provider specifies external nasal valve collapse and indicates it is static, not just nasal blockage.
