ICD-10 Code E83 – Disorders of mineral metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83 – Disorders of mineral metabolism
What it is
E83 identifies disorders involving abnormal metabolism of minerals such as iron, copper, calcium, or phosphorus. Use it when the record documents a mineral metabolism disorder without a more specific subtype.
Clinical signs
Clinical features vary by the mineral involved and the organ affected. Documentation may describe abnormal mineral levels, deficiency or excess states, or related systemic findings; if unclear, refer to the chart.
When to use this code
Use E83 when the clinician documents a general disorder of mineral metabolism and does not name a more specific ICD-10 diagnosis. It may also fit when the note describes a mineral imbalance but lacks enough detail for a narrower code. Check documentation if the record names a specific inherited or acquired condition.
Do not use for
Do not use E83 when the chart supports a more specific disorder of iron, copper, calcium, or phosphorus metabolism. Avoid this code for isolated electrolyte problems or unrelated nutritional deficiencies unless the provider links them to mineral metabolism.
Coding tip
Code to the highest documented specificity; if the mineral or exact disorder is named, choose the more specific code instead of E83.
