Internal nasal valve collapse, static

This code describes a structural narrowing or obstruction within the nasal airway caused by the inward collapse of the internal nasal valve area, which is the narrowest part of the nasal passage. This collapse is considered "static," meaning it is present at rest and does not significantly worsen with inspiration or change with maneuvers like the Cottle test. It results in persistent nasal obstruction.

Use this code when documentation clearly indicates a diagnosis of internal nasal valve collapse that is static in nature. This diagnosis is typically made after a physical examination, often including rhinoscopy, and may be supported by patient complaints of chronic unilateral or bilateral nasal obstruction. The physician's assessment should specify the static characteristic of the collapse.

• Differentiate from dynamic internal nasal valve collapse, which is coded separately and worsens with inspiration.
• Ensure documentation specifies "static" to accurately assign this code.
• Consider co-occurring conditions like septal deviation or turbinate hypertrophy, which may also contribute to nasal obstruction and require additional codes.
