ICD-10 Code E83.19 – Other disorders of iron metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.19 – Other disorders of iron metabolism
What it is
E83.19 identifies disorders of iron handling that do not fit a more specific ICD-10 category. Use it for abnormal iron metabolism when the documentation does not name a distinct hereditary or acquired iron disorder.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records describe abnormal iron studies, iron overload, or iron deficiency patterns tied to a metabolic disorder rather than a simple nutritional problem.
When to use this code
Use E83.19 when the clinician documents a disorder of iron metabolism without a more specific diagnosis. It also fits cases where the chart notes abnormal iron processing, deposition, or storage and no other ICD-10 code is supported.
If the note identifies a specific condition such as hemochromatosis or iron deficiency anemia, code that condition instead. Check documentation for whether the issue is primary, secondary, or part of another disease process.
Do not use for
Do not use this code for routine iron deficiency anemia or documented hemochromatosis. If the record names a different iron-related disorder, choose the more specific code.
Coding tip
Code E83.19 only when the provider clearly documents a nonspecific iron metabolism disorder and no more precise diagnosis is available.
