Disorders of copper metabolism

This code represents conditions characterized by an imbalance in the body's copper levels, either due to excessive accumulation or deficient absorption/utilization. These disorders can lead to a range of systemic issues affecting organs such as the liver, brain, and kidneys. The most well-known conditions falling under this category are Wilson's disease and Menkes disease.

Use this code for diagnoses of inherited or acquired conditions where copper metabolism is disrupted. This includes documentation of Wilson's disease, Menkes disease, or other specified disorders of copper transport or storage. Supporting documentation should include genetic testing results, elevated or decreased serum copper/ceruloplasmin levels, liver biopsy findings, or neurological symptoms consistent with copper dysregulation.

• Differentiate between copper excess (e.g., Wilson's disease) and copper deficiency (e.g., Menkes disease) as both fall under this general category.
• Ensure documentation specifies the particular disorder of copper metabolism when possible, as this code is a broad category.
• Consider sequencing this code as a primary diagnosis when the copper metabolism disorder is the main reason for the encounter, or as a secondary diagnosis when it's a comorbidity impacting treatment.
