ICD-10 Code J95.84 – Transfusion-related acute lung injury (TRALI) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J95.84 – Transfusion-related acute lung injury (TRALI)
What it is
J95.84 identifies transfusion-related acute lung injury, an acute respiratory complication that occurs after a blood transfusion. Use it when documentation states TRALI or transfusion-associated acute lung injury.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe sudden respiratory distress, hypoxemia, and new bilateral pulmonary infiltrates developing during or soon after transfusion.
When to use this code
Use this code when the clinician documents TRALI as the diagnosis tied to a transfusion event. It is appropriate for cases where acute lung injury is attributed to transfused blood products. If the record only says post-transfusion shortness of breath without TRALI, check documentation.
Do not use for
Do not use it for general transfusion reactions, fluid overload, or respiratory symptoms without a documented TRALI diagnosis. Check documentation if the cause of lung findings is unclear.
Coding tip
Link J95.84 to the transfusion-related event in the record and confirm the provider explicitly identifies TRALI.
