Desquamative interstitial pneumonia
ICD-10 J84.117 is a billable code used to indicate a diagnosis of desquamative interstitial pneumonia.
Desquamative interstitial pneumonia (DIP) is a rare lung condition characterized by the accumulation of macrophages in the alveolar spaces, leading to inflammation and fibrosis of the lung parenchyma. Clinically, patients often present with progressive dyspnea, cough, and hypoxemia. The condition primarily affects middle-aged adults, with a higher prevalence in smokers. Anatomically, DIP involves the alveoli and interstitial spaces of the lungs, where the inflammatory process disrupts normal gas exchange. Disease progression can lead to significant pulmonary impairment and may require lung transplantation in severe cases. Diagnostic considerations include high-resolution computed tomography (HRCT) scans showing ground-glass opacities and reticular patterns, along with lung biopsy to confirm the presence of desquamated macrophages. Differential diagnoses include other interstitial lung diseases such as idiopathic pulmonary fibrosis and sarcoidosis, making accurate diagnosis crucial for appropriate management.

J84.117 specifically covers desquamative interstitial pneumonia, which is characterized by the presence of macrophages in the alveolar spaces and is often associated with smoking. It is distinct from other interstitial lung diseases such as idiopathic pulmonary fibrosis and hypersensitivity pneumonitis.
J84.117 should be used when the clinical presentation and diagnostic findings specifically indicate desquamative interstitial pneumonia, particularly when confirmed by lung biopsy and imaging that shows characteristic patterns. It is important to differentiate it from other interstitial lung diseases to ensure appropriate treatment.
Documentation for J84.117 should include a thorough clinical history, results from high-resolution CT scans showing ground-glass opacities, and histopathological findings from lung biopsy confirming the presence of desquamated macrophages in the alveoli.
