ICD-10 Code E83.00 – Disorder of copper metabolism, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E83.00 – Disorder of copper metabolism, unspecified
What it is
E83.00 identifies an unspecified disorder of copper metabolism. Use it when the record documents a copper handling problem but does not name a specific cause or subtype.
Clinical signs
Clinical features vary; refer to documentation. Copper metabolism disorders may be associated with abnormal copper accumulation or deficiency, and findings often depend on the underlying condition.
When to use this code
Use this code when the provider documents a disorder of copper metabolism without further detail. It may fit incomplete diagnoses, pending workups, or charted copper metabolism abnormalities when the specific disorder is not stated.
Do not infer a more specific copper-related diagnosis from test results alone. Code the documented condition exactly as written unless the record clearly supports a more specific option.
Do not use for
Do not use E83.00 for a confirmed, more specific copper disorder such as a named inherited condition. Check documentation and code the exact diagnosis instead of the unspecified category.
Coding tip
If the note only says “copper metabolism disorder,” this code is appropriate; if a specific disorder is named, choose the more precise code.
