ICD-10 Code J70.2 – Acute drug-induced interstitial lung disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J70.2 – Acute drug-induced interstitial lung disorders
What it is
This code identifies an acute interstitial lung disorder caused by a medication or other drug exposure. Use it when the lung injury is documented as drug-induced and has an acute presentation.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see new respiratory symptoms, imaging evidence of interstitial lung involvement, and a clinician’s attribution to a drug cause.
When to use this code
Use J70.2 when the provider documents an acute interstitial lung disorder due to a specific drug or medication. It fits cases where the lung condition is clearly linked to drug exposure and not to infection or another primary lung disease.
Code the drug-induced lung disorder when it is the confirmed reason for the encounter or a significant documented condition. Check documentation for the causative agent, because the medication may need separate coding if required by your setting.
Do not use for
Do not use this code for chronic drug-related lung disease or for unspecified pulmonary reactions without documented interstitial involvement. If the cause or diagnosis is unclear, check documentation.
Coding tip
Look for explicit provider wording such as “drug-induced” and “acute interstitial lung disorder” before assigning J70.2.
