Lymphoid interstitial pneumonia
ICD-10 J84.2 is a billable code used to indicate a diagnosis of lymphoid interstitial pneumonia.
Lymphoid interstitial pneumonia (LIP) is a rare lung condition characterized by the proliferation of lymphoid tissue in the interstitial spaces of the lungs. Clinically, patients may present with symptoms such as chronic cough, dyspnea, and fatigue, often leading to a misdiagnosis of other respiratory conditions. The anatomy involved includes the alveoli and interstitial spaces of the lungs, where the abnormal lymphoid tissue disrupts normal gas exchange. Disease progression can vary; some patients may experience stable disease, while others may progress to pulmonary fibrosis or respiratory failure. Diagnostic considerations include high-resolution computed tomography (HRCT) scans, which reveal characteristic ground-glass opacities and reticular patterns, and lung biopsy, which is essential for confirming the diagnosis. LIP is often associated with autoimmune conditions, particularly Sjögren's syndrome, and can occur in immunocompromised patients, making a thorough clinical history and examination critical for accurate diagnosis and management.

J84.2 specifically covers lymphoid interstitial pneumonia, which may be associated with conditions such as Sjögren's syndrome, HIV infection, and other immunocompromised states. It is important to differentiate it from other interstitial lung diseases.
J84.2 should be used when the diagnosis of lymphoid interstitial pneumonia is confirmed through clinical evaluation and histological evidence. It is distinct from other interstitial lung diseases that do not involve lymphoid proliferation.
Documentation should include a detailed clinical history, imaging studies (such as HRCT), and results from lung biopsies that confirm lymphoid interstitial pneumonia. Additionally, any associated autoimmune conditions should be documented.
