ICD-10 Code E83.10 – Disorder of iron metabolism, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.10 – Disorder of iron metabolism, unspecified
What it is
E83.10 identifies a disorder affecting iron metabolism when the specific type is not documented. Use it for a confirmed iron-handling problem, but not for simple abnormal iron studies alone.
Clinical signs
Clinical features vary; refer to documentation. Records may note iron overload, iron deficiency, or another iron-processing abnormality, but the exact pattern is not specified in the diagnosis.
When to use this code
Use this code when the provider documents a disorder of iron metabolism and does not name a more specific condition. It is appropriate when the chart only states an unspecified iron metabolism disorder or similar wording. If the record identifies hemochromatosis, iron deficiency, or another defined diagnosis, code that condition instead.
Do not use for
Do not use E83.10 for isolated abnormal laboratory results without a diagnosis. Do not use it when a more specific iron disorder is documented; check documentation.
Coding tip
Code the most specific iron-related diagnosis available, and use E83.10 only when the provider leaves the disorder unspecified.
