ICD10 code of Wilsons disease and ICD9 code

Wilson disease is classified under the ICD-10 code E83.01 for "Wilson's disease" (specifically, disorders of copper metabolism), while the corresponding ICD-9 code is 275.1. These medical billing codes are used internationally to identify Wilson disease for clinical documentation, insurance reimbursement, and health record tracking.

What is the clinical significance of the Wilson disease ICD codes?

The use of specific ICD-10 and ICD-9 codes is essential for patients living with Wilson disease to ensure proper coding for specialized diagnostic tests and long-term pharmacological treatments. Because Wilson disease is a rare genetic disorder characterized by the body's inability to properly excrete copper, leading to toxic accumulation in the liver, brain, and other vital organs, accurate coding helps healthcare providers track disease progression and manage life-long therapy. At DiseaseMaps.org, 161 people with Wilson disease have shared their experiences, highlighting how these diagnostic codes often serve as the first step in formalizing a patient's journey toward specialized care and community support.

How is Wilson disease diagnosed and categorized?

Diagnosis of Wilson disease typically involves a combination of clinical assessment and laboratory testing. Because the condition is progressive, early identification using the correct medical codes is vital for effective management. Physicians generally look for specific markers to confirm the diagnosis:

• Ceruloplasmin levels: Low serum ceruloplasmin is a primary indicator, though not present in all cases.


• 24-hour urinary copper: Elevated copper excretion is a hallmark of the disease.


• Kayser-Fleischer rings: A slit-lamp eye examination often reveals these copper deposits in the cornea, common in patients with neurological symptoms.


• Genetic testing: Analysis of the ATP7B gene, located on chromosome 13, confirms the diagnosis of Wilson disease.

Is Wilson disease hereditary?

Wilson disease is an autosomal recessive genetic disorder, meaning that an individual must inherit two copies of the mutated ATP7B gene—one from each parent—to develop the condition. Parents of a child with Wilson disease are typically asymptomatic carriers. Genetic counseling is strongly recommended for families affected by Wilson disease to understand the 25% recurrence risk for each subsequent pregnancy. Understanding the genetic basis of Wilson disease is crucial for identifying affected siblings or relatives who may be asymptomatic but require early intervention to prevent organ damage.

What is the impact of Wilson disease on the liver and brain?

Wilson disease primarily manifests through hepatic (liver) and neurological dysfunction. The clinical spectrum of Wilson disease is broad; some patients present with liver cirrhosis or hepatitis, while others may experience tremors, dystonia, or psychiatric symptoms due to copper deposition in the basal ganglia of the brain. Because symptoms of Wilson disease can mimic other conditions, maintaining accurate medical records using the correct ICD codes (E83.01) is critical for coordinating care between hepatologists, neurologists, and geneticists.

Next steps

• Consult a hepatologist or a metabolic disease specialist if you suspect symptoms of Wilson disease.


• Request a 24-hour urine copper test and a slit-lamp eye examination as part of your clinical evaluation.


• Connect with the 161 community members at DiseaseMaps.org to share experiences and find resources for managing the daily challenges of Wilson disease.


• Ensure your medical records use the correct ICD-10 code (E83.01) to facilitate insurance coverage for long-term copper-chelating therapies.
