ICD-10 Code E83.111 – Hemochromatosis due to repeated red blood cell transfusions (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.111 – Hemochromatosis due to repeated red blood cell transfusions
What it is
This code identifies iron overload caused by repeated red blood cell transfusions. The condition reflects excess iron accumulation in the body, not inherited hemochromatosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include evidence of iron overload, organ involvement, or a history of chronic transfusion therapy.
When to use this code
Use this code when the provider documents hemochromatosis or iron overload specifically due to repeated transfusions. It fits patients receiving long-term transfusion support, such as for chronic anemias. Code it only when the transfusion cause is clearly stated.
Do not use for
Do not use it for hereditary hemochromatosis or iron overload from other causes. Check documentation if the record only says “iron overload” without linking it to transfusions.
Coding tip
Look for explicit wording such as “due to transfusions” before assigning E83.111.
