ICD-10 Code E83.1 – Disorders of iron metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.1 – Disorders of iron metabolism
What it is
E83.1 identifies disorders involving abnormal iron handling in the body. Use it when the record describes an iron metabolism problem, such as abnormal storage or transport, without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Records may describe iron overload, iron deficiency related to metabolism, or other abnormal iron studies tied to a metabolic disorder.
When to use this code
Use E83.1 when the provider documents a disorder of iron metabolism and does not name a more specific condition. It may fit cases discussed as abnormal iron handling, iron accumulation, or inherited/metabolic iron disorders. Check documentation for the exact clinical term before coding.
Do not use for
Do not use this code for routine iron deficiency anemia, blood loss anemia, or isolated abnormal lab results without a documented metabolic disorder. If the chart gives a specific diagnosis, code that condition instead.
Coding tip
Code the most specific iron-related diagnosis documented, and query when the note only says “abnormal iron” or “iron studies abnormal.”
