ICD10 code of Charcot-Marie-Tooth Disease and ICD9 code

Charcot-Marie-Tooth disease (CMT) is primarily classified under the ICD-10 code G60.0, which refers to hereditary motor and sensory neuropathy. In the older ICD-9-CM classification system, Charcot-Marie-Tooth disease is most commonly coded as 356.1.

What is Charcot-Marie-Tooth disease and how is it classified?

Charcot-Marie-Tooth disease is a group of inherited disorders that cause nerve damage, primarily in the arms and legs. It is characterized by progressive muscle weakness, atrophy, and sensory loss. Because there are many genetic subtypes of Charcot-Marie-Tooth disease, medical coding helps clinicians and researchers track the progression and prevalence of these specific neuropathies. While G60.0 is the standard ICD-10 code, clinicians may also use additional codes to document specific complications such as foot deformities or chronic pain.

What are the primary clinical features of Charcot-Marie-Tooth disease?

The clinical presentation of Charcot-Marie-Tooth disease often begins with distal muscle weakness and sensory changes. Patients frequently experience high arches (pes cavus), hammertoes, and foot drop, which can lead to frequent falls and balance issues. As the condition affects the peripheral nervous system, individuals often report a "burning" sensation in the feet, cold extremities, and chronic fatigue. In some variants of Charcot-Marie-Tooth disease, patients may also face difficulties with swallowing or respiratory muscle weakness, necessitating a multidisciplinary care approach.

How is Charcot-Marie-Tooth disease managed?

Currently, there is no cure for Charcot-Marie-Tooth disease, so management focuses on maintaining mobility and quality of life. At DiseaseMaps.org, our community of 1,193 members highlights the importance of a coordinated care team. Standard management strategies include:

• Physical Therapy: To maintain muscle strength, improve balance, and prevent contractures.


• Orthopedic Intervention: Use of custom bracing (AFOs) to address foot drop and prevent falls.


• Podiatric Care: Specialized footwear or surgical intervention to manage skeletal deformities.


• Pain Management: Medications targeted at neuropathic pain and sensory discomfort.


• Occupational Therapy: Adaptive strategies for daily activities affected by hand weakness.

Is Charcot-Marie-Tooth disease hereditary?

Yes, Charcot-Marie-Tooth disease is a genetic condition. It can be inherited in an autosomal dominant, autosomal recessive, or X-linked pattern depending on the specific gene mutation involved. Genetic counseling is highly recommended for families to understand the inheritance risks for future generations. Because the symptoms of Charcot-Marie-Tooth disease can vary significantly even within the same family, clinical genetic testing is often required to confirm the specific type and prognostic outlook.

Next steps

• Consult with a neurologist specializing in peripheral nerve disorders or clinical neurophysiology.


• Request a referral to a genetic counselor to discuss the specific inheritance pattern of your diagnosis.


• Join the 1,193 members at DiseaseMaps.org to share experiences and find local support groups.


• Maintain a symptom diary to help your care team track the progression of pain, fatigue, and mobility changes.


• Discuss current clinical trials and research opportunities with your physician to stay informed on emerging therapies.
