ICD-10 Code E83.09 – Other disorders of copper metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.09 – Other disorders of copper metabolism
What it is
E83.09 identifies disorders affecting how the body handles copper when the condition does not fit a more specific copper-metabolism diagnosis. Use it for documented abnormalities of copper processing, storage, or balance.
Clinical signs
Clinical features vary; refer to documentation. Findings may reflect abnormal copper accumulation or deficiency, with possible liver, neurologic, or other systemic involvement depending on the underlying disorder.
When to use this code
Use this code when the record clearly states an other, unspecified, or atypical disorder of copper metabolism and no more specific code is documented. It may apply after evaluation of abnormal copper handling, if the provider names the condition but does not identify a different copper-related diagnosis.
Do not use for
Do not use E83.09 if the documentation supports a more specific copper disorder, such as Wilson disease or copper deficiency. Check documentation when the chart only mentions abnormal copper studies without a defined metabolic disorder.
Coding tip
Code the provider’s exact copper-metabolism diagnosis, and query if the record is nonspecific or conflicts with a more specific condition.
