ICD-10 Code J70.0 – Acute pulmonary manifestations due to radiation (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J70.0 – Acute pulmonary manifestations due to radiation
What it is
J70.0 identifies acute lung injury or inflammation caused by radiation exposure. Use it when the record documents a pulmonary reaction directly linked to radiation therapy or other radiation exposure.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include cough, shortness of breath, chest discomfort, and imaging evidence of inflammatory lung changes after radiation.
When to use this code
Use this code when the provider documents an acute pulmonary manifestation due to radiation, such as radiation pneumonitis or similar acute radiation-related lung injury. Confirm that the cause is radiation, not infection, heart failure, or another lung disorder. If the note is unclear, check documentation before assigning the code.
Do not use for
Do not use J70.0 for chronic radiation lung damage or for nonspecific respiratory symptoms without a documented radiation cause. Do not assign it when another diagnosis better explains the pulmonary findings.
Coding tip
Link the lung condition to radiation explicitly in the provider note before coding J70.0.
