Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G25.5:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Chorea NOS

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
  • chorea NOS with heart involvement I02.0
  • Huntington's chorea G10
  • rheumatic chorea I02
  • Sydenham's chorea I02

Clinical Information

  • CHOREA-. involuntary forcible rapid jerky movements that may be subtle or become confluent markedly altering normal patterns of movement. hypotonia and pendular reflexes are often associated. conditions which feature recurrent or persistent episodes of chorea as a primary manifestation of disease are referred to as choreatic disorders. chorea is also a frequent manifestation of basal ganglia diseases.
  • HUNTINGTON DISEASE-. a familial disorder inherited as an autosomal dominant trait and characterized by the onset of progressive chorea and dementia in the fourth or fifth decade of life. common initial manifestations include paranoia; poor impulse control; depression; hallucinations; and delusions. eventually intellectual impairment; loss of fine motor control; athetosis; and diffuse chorea involving axial and limb musculature develops leading to a vegetative state within 10 15 years of disease onset. the juvenile variant has a more fulminant course including seizures; ataxia; dementia; and chorea. from adams et al. principles of neurology 6th ed pp1060 4
  • CHOREA GRAVIDARUM-. a rare movement disorder developed during pregnancy characterized by involuntary jerky motion chorea and inability to maintain stable position of body parts athetosis. rheumatic fever and collagen vascular disorders are frequently associated with this disease. chorea may vary from mild to severe and occurs in approximately 1 per 2000 to 3000 pregnancies. from md med j 1997 sep;468:436 9
  • TICS-. habitual repeated rapid contraction of certain muscles resulting in stereotyped individualized actions that can be voluntarily suppressed for only brief periods. they often involve the face vocal cords neck and less often the extremities. examples include repetitive throat clearing vocalizations sniffing pursing the lips and excessive blinking. tics tend to be aggravated by emotional stress. when frequent they may interfere with speech and interpersonal relations. conditions which feature frequent and prominent tics as a primary manifestation of disease are referred to as tic disorders. from adams et al. principles of neurology 6th ed pp109 10
  • MYOKYMIA-. successive and rapid contractions of motor units associated with chronic nerve injury. the discharges arise from the peripheral aspects of regenerating nerves and clinically impart a nearly continuous undulation of the body surface overlying the muscle. adams et al. principles of neurology 6th ed p1491
  • NEUROACANTHOCYTOSIS-. an inherited autosomal disorder that is characterized by neurodegeneration; orofacial and buccal dyskinesias; chorea; and thorny looking red cells acanthocytes. this disorder is due to mutations of chorein which is important in protein trafficking and is encoded by vps13a on chromosome 9q21.

Information for Patients

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.
