ICD-10 Code E83.0 – Disorders of copper metabolism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.0 – Disorders of copper metabolism
What it is
E83.0 identifies disorders involving abnormal copper handling in the body. Use it when documentation shows a copper metabolism problem, such as impaired absorption, transport, storage, or excretion.
Clinical signs
Clinical features vary; refer to documentation. Findings may include signs of copper overload or deficiency, and in some disorders, liver or neurologic involvement is noted.
When to use this code
Use E83.0 when the provider documents a disorder of copper metabolism without naming a more specific diagnosis. It also fits cases where the chart describes abnormal copper metabolism, copper accumulation, or a related inherited condition. If the record names a specific disease, code that condition instead.
Do not use for
Do not use this code for nonspecific abnormal laboratory results alone unless the provider links them to a copper metabolism disorder. Check documentation if the condition is better classified under a specific genetic, hepatic, or neurologic diagnosis.
Coding tip
Query for the exact copper-related diagnosis when the note is vague, because a more specific code may be available.
