ICD-10 Code E83.11 – Hemochromatosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.11 – Hemochromatosis
What it is
Hemochromatosis is a disorder of iron overload in which the body stores too much iron. The excess iron can accumulate in organs and cause damage over time.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include fatigue, skin darkening, joint pain, liver enlargement, or evidence of iron overload on evaluation.
When to use this code
Use E83.11 when the provider documents hemochromatosis or hereditary iron overload as the diagnosis. It is appropriate when the record supports iron accumulation disorder, with or without organ involvement.
Code this when the condition is confirmed or clearly assessed in the note. Check documentation if the record only mentions abnormal iron studies without a diagnosis.
Do not use for
Do not use this code for nonspecific iron deficiency, anemia, or isolated abnormal laboratory results without a diagnosis. Check documentation if the note describes a different iron metabolism disorder.
Coding tip
Confirm whether the provider documented hemochromatosis specifically, rather than just elevated iron levels, before assigning E83.11.
