ICD10 code of Menkes Disease and ICD9 code

Menkes disease is primarily classified under ICD-10 code E83.01 (Copper deficiency) and historically under ICD-9 code 275.0 (Disorders of copper metabolism). Because Menkes disease is a rare, X-linked recessive neurodegenerative disorder, these codes serve as the clinical billing and diagnostic markers used by healthcare providers to track the condition within medical systems.

What is the clinical significance of Menkes disease coding?

In clinical practice, coding for Menkes disease is essential for insurance authorization, specialized care coordination, and epidemiological tracking. Because Menkes disease is a multisystemic disorder caused by mutations in the ATP7A gene, it results in severe copper deficiency throughout the body. While ICD-10 E83.01 is the standard, clinicians often utilize additional codes to document specific manifestations, such as seizures (G40) or developmental delays (F88), to ensure comprehensive management of the patient's complex needs.

How is Menkes disease diagnosed and classified?

The diagnosis of Menkes disease typically occurs in early infancy, often within the first few months of life. Physicians identify the condition through a combination of clinical observation—such as sparse, kinky, or colorless hair (pili torti)—and biochemical testing. Genetic testing for ATP7A mutations remains the gold standard for confirmation. At DiseaseMaps.org, 74 people with Menkes disease have shared their experiences, highlighting the importance of early diagnosis and the challenges families face in navigating the healthcare system for such a rare condition.

What are the primary features of Menkes disease?

Menkes disease is characterized by a systemic failure to transport copper, which is vital for the function of numerous enzymes. This leads to a cascade of neurological and connective tissue symptoms. Common clinical features include:

• Neurological decline: Progressive loss of developmental milestones, hypotonia, and infantile spasms.


• Connective tissue abnormalities: Characteristic "kinky" hair, skin laxity, and vascular complications.


• Biochemical markers: Low serum copper and low serum ceruloplasmin levels.


• Skeletal findings: Wormian bones and metaphyseal spurring often visible on radiographs.

Is Menkes disease hereditary?

Yes, Menkes disease is an X-linked recessive disorder. This means the gene responsible for the condition is located on the X chromosome. Because males only have one X chromosome, they are almost exclusively affected by Menkes disease. Female carriers usually do not show symptoms, though they have a 50% chance of passing the gene mutation to their offspring. Genetic counseling is strongly recommended for families affected by Menkes disease to understand the recurrence risks and available reproductive options.

Next steps

• Consult a specialist: Work with a metabolic geneticist or a pediatric neurologist experienced in copper metabolism disorders.


• Genetic counseling: Meet with a board-certified genetic counselor to discuss familial risk and carrier testing.


• Join a community: Connect with the 74 members at DiseaseMaps.org to share resources and find emotional support from families navigating similar paths.


• Registry participation: Inquire about international patient registries to assist researchers in gathering data on rare variants of Menkes disease.
