ICD-10 Code J34.8200 – Internal nasal valve collapse, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J34.8200 – Internal nasal valve collapse, unspecified
What it is
J34.8200 identifies collapse of the internal nasal valve without further detail. This code is used when the chart documents internal nasal valve narrowing or collapse, but laterality or cause is not specified.
Clinical signs
Typical findings include nasal airway obstruction, especially during inspiration, and improvement with maneuvers that support the nasal sidewall. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents internal nasal valve collapse and does not specify left, right, or bilateral involvement. It may also fit when the record describes valve collapse as the cause of nasal obstruction, but details are incomplete. Check documentation if the note suggests a different nasal structural problem.
Do not use for
Do not use it for general nasal congestion, deviated septum, or external nasal valve collapse unless the internal valve is clearly documented. Do not assign it when the record only says “nasal obstruction” without valve collapse.
Coding tip
Query the provider for laterality or greater specificity when the note lacks enough detail for the unspecified code.
