Idiopathic interstitial pneumonia
ICD-10 J84.11 is a used to indicate a diagnosis of idiopathic interstitial pneumonia.
Idiopathic interstitial pneumonia (IIP) is a group of lung diseases characterized by inflammation and scarring (fibrosis) of the lung tissue. The term 'idiopathic' indicates that the cause of the disease is unknown. Clinically, patients may present with symptoms such as progressive dyspnea (shortness of breath), a persistent dry cough, and fatigue. The disease primarily affects the interstitium, the tissue and space around the air sacs of the lungs, leading to impaired gas exchange. Over time, the progressive fibrosis can result in significant respiratory compromise and reduced lung function. Diagnostic considerations include high-resolution computed tomography (HRCT) scans, which can reveal characteristic patterns of lung involvement, and lung biopsy may be necessary for definitive diagnosis. Pulmonary function tests are also essential to assess the extent of lung impairment. Early diagnosis and management are crucial to improve patient outcomes and quality of life.

J84.11 specifically covers idiopathic interstitial pneumonia, which includes various forms of IIP such as idiopathic pulmonary fibrosis (IPF) and other unclassifiable interstitial lung diseases without a known cause.
J84.11 should be used when a patient presents with symptoms and diagnostic findings consistent with idiopathic interstitial pneumonia, and other known causes of interstitial lung disease have been ruled out.
Documentation should include a comprehensive clinical history, results from imaging studies (such as HRCT), pulmonary function tests, and any biopsy results that support the diagnosis of idiopathic interstitial pneumonia.
