Idiopathic non-specific interstitial pneumonitis
ICD-10 J84.113 is a billable code used to indicate a diagnosis of idiopathic non-specific interstitial pneumonitis.
Idiopathic non-specific interstitial pneumonitis (NSIP) is a form of interstitial lung disease characterized by inflammation and fibrosis of the lung interstitium. Clinically, patients often present with progressive dyspnea, cough, and fatigue, which can lead to significant impairment in quality of life. The disease primarily affects the alveolar walls and surrounding tissues, leading to scarring that impairs gas exchange. The etiology remains unknown, hence the term 'idiopathic.' Disease progression can vary, with some patients experiencing a gradual decline in lung function, while others may have a more rapid deterioration. Diagnostic considerations include high-resolution computed tomography (HRCT) scans, which typically reveal ground-glass opacities and reticular patterns, and lung biopsy may be necessary to confirm the diagnosis and rule out other interstitial lung diseases. Pulmonary function tests often show a restrictive pattern, and the absence of identifiable causes such as autoimmune diseases, drug toxicity, or environmental exposures is crucial for establishing the diagnosis of idiopathic NSIP.

J84.113 specifically covers idiopathic non-specific interstitial pneumonitis, which is characterized by a pattern of lung inflammation and fibrosis without an identifiable cause. It is distinct from other forms of interstitial lung disease, such as those associated with autoimmune disorders or environmental exposures.
J84.113 should be used when the clinical presentation aligns with idiopathic non-specific interstitial pneumonitis, and other potential causes have been ruled out. It is essential to document the idiopathic nature of the condition to differentiate it from other interstitial lung diseases.
Documentation for J84.113 should include a thorough clinical history, results from pulmonary function tests, imaging findings from HRCT scans, and any biopsy results that confirm the diagnosis while excluding other causes of interstitial lung disease.
