ICD-10 Code J84.848 – Other interstitial lung diseases of childhood (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J84.848 – Other interstitial lung diseases of childhood
What it is
This code identifies interstitial lung disease in a child when the condition does not fit a more specific ICD-10-CM category. It covers chronic disorders affecting the lung interstitium and requiring documentation beyond a general lung diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include persistent cough, shortness of breath, exercise intolerance, and abnormal chest imaging consistent with interstitial lung disease.
When to use this code
Use J84.848 when the provider documents an interstitial lung disease of childhood and no more specific code is available. Apply it for pediatric cases described as other, unspecified subtype, or not otherwise classified. Confirm that the record supports a childhood interstitial process rather than an adult-onset or unrelated lung disorder.
Do not use for
Do not use this code for a clearly identified interstitial lung disease with its own specific ICD-10-CM code. Check documentation if the condition is acute infection, asthma, or another non-interstitial pulmonary disorder.
Coding tip
Code only after you verify that the provider documented a childhood interstitial lung disease and that no more specific diagnosis is stated.
