ICD-10-CM Code G11.8

Other hereditary ataxias

Version 2021 Billable Code

Valid for Submission

G11.8 is a billable code used to specify a medical diagnosis of other hereditary ataxias. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code G11.8 might also be used to specify conditions or terms like abnormal saccadic eye movement, arts syndrome, ataxia pancytopenia syndrome, ataxia, photosensitivity, short stature syndrome, autosomal recessive cerebellar ataxia beauce type, autosomal recessive cerebellar ataxia with saccadic intrusion syndrome, etc

Clinical Information

  • FRIEDREICH ATAXIA-. an autosomal recessive disease usually of childhood onset characterized pathologically by degeneration of the spinocerebellar tracts posterior columns and to a lesser extent the corticospinal tracts. clinical manifestations include gait ataxia pes cavus speech impairment lateral curvature of spine rhythmic head tremor kyphoscoliosis congestive heart failure secondary to a cardiomyopathy and lower extremity weakness. most forms of this condition are associated with a mutation in a gene on chromosome 9 at band q13 which codes for the mitochondrial protein frataxin. from adams et al. principles of neurology 6th ed p1081; n engl j med 1996 oct 17;33516:1169 75 the severity of friedreich ataxia associated with expansion of gaa repeats in the first intron of the frataxin gene correlates with the number of trinucleotide repeats. from durr et al n engl j med 1996 oct 17;33516:1169 75
  • SPINOCEREBELLAR DEGENERATIONS-. a heterogenous group of degenerative syndromes marked by progressive cerebellar dysfunction either in isolation or combined with other neurologic manifestations. sporadic and inherited subtypes occur. inheritance patterns include autosomal dominant autosomal recessive and x linked.

Information for Patients


Cerebellar Disorders

When you play the piano or hit a tennis ball you are activating the cerebellum. The cerebellum is the area of the brain that controls coordination and balance. Problems with the cerebellum include

  • Cancer
  • Genetic disorders
  • Ataxias - failure of muscle control in the arms and legs that result in movement disorders
  • Degeneration - disorders caused by brain cells decreasing in size or wasting away

Treatment of cerebellar disorders depends on the cause. In some cases, there is no cure but treatment may help with symptoms.

Movement Disorders

Movement disorders are neurologic conditions that cause problems with movement, such as

  • Increased movement that can be voluntary (intentional) or involuntary (unintended)
  • Decreased or slow voluntary movement

There are many different movement disorders. Some of the more common types include

  • Ataxia, the loss of muscle coordination
  • Dystonia, in which involuntary contractions of your muscles cause twisting and repetitive movements. The movements can be painful.
  • Huntington's disease, an inherited disease that causes nerve cells in certain parts of the brain to waste away. This includes the nerve cells that help to control voluntary movement.
  • Parkinson's disease, which is disorder that slowly gets worse over time. It causes tremors, slowness of movement, and trouble walking.
  • Tourette syndrome, a condition which causes people to make sudden twitches, movements, or sounds (tics)
  • Tremor and essential tremor, which cause involuntary trembling or shaking movements. The movements may be in one or more parts of your body.

Causes of movement disorders include

  • Genetics
  • Infections
  • Medicines
  • Damage to the brain, spinal cord, or peripheral nerves
  • Metabolic disorders
  • Stroke and vascular diseases
  • Toxins

Treatment varies by disorder. Medicines can cure some disorders. Others get better when an underlying disease is treated. Often, however, there is no cure. In that case, the goal of treatment is to improve symptoms and relieve pain.
