Wilson's disease

This code identifies Wilson's disease, an inherited disorder characterized by excessive copper accumulation in the body's tissues, primarily the liver, brain, and eyes. This genetic defect in copper metabolism leads to a range of symptoms, including hepatic dysfunction, neurological impairment, and Kayser-Fleischer rings.

Assign this code for patients diagnosed with Wilson's disease, confirmed through clinical presentation, laboratory findings (e.g., low ceruloplasmin, elevated urinary copper), and/or genetic testing. It is appropriate for both initial diagnosis and ongoing management of the condition. Documentation should clearly state the diagnosis of Wilson's disease.

• Do not confuse with other metabolic disorders affecting heavy metals; ensure documentation specifically states "Wilson's disease."
• Code any associated manifestations (e.g., cirrhosis, neurological deficits) separately as secondary diagnoses.
• Review genetic testing results or liver biopsy findings if available, as they provide strong supporting documentation.
