2025 ICD-10-CM code J84.2
(Active) Effective Date: N/A Diseases of the respiratory system - Other interstitial pulmonary diseases with fibrosis 10 Feed
Lymphoid interstitial pneumonia. Clinically known as lymphoid interstitial pneumonitis.
Medical necessity for services related to J84.2 must be supported by documentation of the diagnosis and its impact on the patient's respiratory function. This includes the severity of symptoms, impairment of lung function, and need for interventions such as oxygen therapy, medications, or pulmonary rehabilitation.
Diagnosis and treatment of lymphoid interstitial pneumonia typically falls under the purview of pulmonologists (lung specialists). They may collaborate with other specialists depending on associated conditions, such as immunologists or rheumatologists.

In simple words: This is a lung disease where a specific type of white blood cell, called a lymphocyte, builds up in the lungs, making it difficult to breathe.It's unusual and often linked to other health problems.
Lymphoid interstitial pneumonia is a rare condition characterized by the infiltration of lymphocytes into the interstitium (the tissue and space around the air sacs) of the lungs.
Example 1: A 50-year-old patient presents with progressive shortness of breath, cough, and fatigue. Imaging studies reveal diffuse interstitial infiltrates, and a lung biopsy confirms the diagnosis of lymphoid interstitial pneumonia., A child with a known autoimmune disorder develops respiratory symptoms. Further investigation reveals lymphoid interstitial pneumonia as a secondary complication., A patient with HIV infection is found to have lymphoid interstitial pneumonia during a routine chest X-ray, even in the absence of prominent respiratory symptoms.
Documentation for J84.2 should include:* Detailed history and physical exam findings, including the onset and nature of respiratory symptoms.* Imaging studies (chest X-ray, CT scan) demonstrating characteristic patterns of lung involvement.* Pulmonary function tests to assess lung capacity and function.* Lung biopsy results confirming the presence of lymphocytic infiltration in the interstitium.* Any associated underlying conditions, such as autoimmune diseases or HIV infection.
** Lymphoid interstitial pneumonia is often associated with underlying conditions like autoimmune disorders (e.g., Sjögren's syndrome, rheumatoid arthritis) and HIV infection. It’s important to investigate and document any such associations. For accurate diagnosis and treatment, consider using specialized diagnostic tools like iFrameAI for detailed image analysis and clinical decision support, which may provide more specific insights beyond traditional ICD codes.
