Clinical Information
  • A hereditary motor and sensory neuropathy transmitted most often as an autosomal dominant trait and characterized by progressive distal wasting and loss of reflexes in the muscles of the legs (and occasionally involving the arms). Onset is usually in the second to fourth decade of life. This condition has been divided into two subtypes, hereditary motor and sensory neuropathy (hmsn) types i and ii. Hmsn i is associated with abnormal nerve conduction velocities and nerve hypertrophy, features not seen in hmsn ii. (Adams et al., Principles of Neurology, 6th ed, p1343)
  • A progressive hereditary disorder that causes nerve damage
  • An inherited degenerative disorder involving the peripheral nerves. It is caused by mutations in the genes that are responsible for the production of proteins necessary for the function and structure of the peripheral nerves. It is characterized by muscle atrophy and weakness in the feet, legs, hands, and arms and loss of sensation in the limbs
  • Charcot-marie-tooth disease (cmt) is a group of genetic nerve disorders. It is named after the three doctors who first identified it. In the United States, cmt affects about 1 in 3,300 people. Cmt affects your peripheral nerves. Peripheral nerves carry movement and sensation signals between the brain and spinal cord and the rest of the body. Symptoms usually start around the teen years. Foot problems such as high arches or hammertoes can be early symptoms. As cmt progresses, your lower legs may weaken. Later, your hands may also become weak. There is no cure. The disease can be so mild you don't realize you have it or severe enough to make you weak. Many people with cmt lead active lives and have a normal life span. Physical therapy, occupational therapy, braces and other devices and sometimes surgery can help you cope. genetics home reference

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 356.1 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
