Internal nasal valve collapse, unspecified

This code describes an unspecified collapse of the internal nasal valve, a critical area within the nasal airway responsible for airflow regulation. This condition typically leads to nasal obstruction and difficulty breathing through the nose. It signifies a structural issue affecting the cartilage and soft tissues of the internal nasal valve.

Use this code when documentation indicates internal nasal valve collapse without further specification of laterality (left, right, or bilateral). This code is appropriate when the provider has diagnosed internal nasal valve collapse but has not yet determined or documented the specific side(s) affected. Supporting documentation would include clinical notes describing nasal obstruction attributed to internal nasal valve collapse.

• Avoid using this code if laterality (left, right, or bilateral) is documented; instead, use the more specific codes for internal nasal valve collapse.
• Ensure the documentation clearly states "internal nasal valve collapse" to support this diagnosis.
• This code should be followed by codes for any associated symptoms, such as nasal obstruction (e.g., R09.81).
