External nasal valve collapse, dynamic
ICD-10 J34.8212 is a billable code used to indicate a diagnosis of external nasal valve collapse, dynamic.
External nasal valve collapse, dynamic, refers to a condition where the external nasal valve, which is the narrowest part of the nasal airway, fails to maintain its structural integrity during breathing, particularly during inhalation. This condition can lead to significant airflow obstruction, resulting in symptoms such as nasal congestion, difficulty breathing through the nose, and increased reliance on oral breathing. The anatomy involved includes the nasal cartilages, specifically the lower lateral cartilages, and the surrounding soft tissue structures. Disease progression may vary, with some patients experiencing intermittent symptoms that worsen with physical exertion or during allergy seasons, while others may have persistent issues. Diagnostic considerations include a thorough clinical examination, nasal endoscopy, and possibly imaging studies to assess the nasal anatomy and rule out other causes of nasal obstruction. Functional assessments, such as peak nasal inspiratory flow measurements, may also be utilized to evaluate the severity of the collapse and its impact on respiratory function.

J34.8212 specifically covers dynamic external nasal valve collapse, which can occur due to various factors such as anatomical variations, trauma, or previous nasal surgeries. It is characterized by the inability of the nasal valve to maintain patency during inhalation.
J34.8212 should be used when there is clear evidence of dynamic collapse of the external nasal valve, particularly when symptoms are exacerbated by physical activity or specific positions. It is important to differentiate it from static collapse, which is coded as J34.8211.
Documentation for J34.8212 should include a detailed history of nasal symptoms, results from physical examinations, any imaging studies performed, and the outcomes of functional assessments. Clear notes on the impact of the condition on the patient's quality of life are also beneficial.
