ICD-10 Code E83.118 – Other hemochromatosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.118 – Other hemochromatosis
What it is
E83.118 identifies hemochromatosis that is not classified elsewhere. Use it for documented iron overload conditions when the record does not support a more specific hereditary or secondary code.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include evidence of iron overload, abnormal iron studies, and organ involvement such as liver, heart, or endocrine complications.
When to use this code
Use this code when the clinician documents “other hemochromatosis” or a similar nonspecific iron overload diagnosis. It also fits cases where the type is not stated, but the chart clearly supports hemochromatosis. If the record identifies a specific cause or genetic form, code that condition instead.
Do not use for
Do not use it for hereditary hemochromatosis, transfusional iron overload, or other separately coded iron metabolism disorders. Check documentation if the cause of iron overload is specified.
Coding tip
Assign E83.118 only when the note clearly supports hemochromatosis and no more specific code is documented.
