2025 ICD-10-CM code J70.4
Drug-induced interstitial lung disorders, unspecified. Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5).
Medical necessity for the use of J70.4 must be supported by documentation that clearly establishes the diagnosis of drug-induced interstitial lung disease. This typically includes a combination of clinical findings, imaging studies, pulmonary function tests, and a history of exposure to a causative medication. The documentation should demonstrate a causal relationship between the medication and the lung disease.
The clinician is responsible for documenting the diagnosis of drug-induced interstitial lung disease and specifying the causative drug if known. Additional codes should be used to identify the specific drug and any associated adverse effects.
In simple words: This code signifies unspecified interstitial lung disease caused by a drug.Your doctor may use an additional code to specify the drug causing the problem.
Drug-induced interstitial lung disorders, unspecified. Use additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5). Excludes1: interstitial pneumonia NOS (J84.9) lymphoid interstitial pneumonia (J84.2)
Example 1: A patient presents with shortness of breath, cough, and fatigue. After a thorough examination and review of the patient's medication history, which includes amiodarone, the physician diagnoses drug-induced interstitial lung disease, unspecified., A patient undergoing chemotherapy develops progressive dyspnea and pulmonary infiltrates on imaging. The clinical findings suggest drug-induced interstitial lung disease, but the exact medication responsible cannot be definitively determined., A patient with a history of rheumatoid arthritis treated with methotrexate experiences a decline in pulmonary function.The diagnosis is drug-induced interstitial lung disorder, unspecified.
Documentation should include the patient's symptoms, physical exam findings, medication history, pulmonary function tests, imaging studies (e.g. chest X-ray, CT scan), and any other relevant diagnostic tests. If a specific drug is identified as the cause, it should be documented. Any associated adverse effects should also be noted.
