2020 ICD-10-CM Diagnosis Code G24

Dystonia

    2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
  • G24 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
  • The 2020 edition of ICD-10-CM G24 became effective on October 1, 2019.
  • This is the American ICD-10-CM version of G24 - other international versions of ICD-10 G24 may differ.
Type 2 Excludes
Type 2 Excludes Help
A type 2 excludes note represents "not included here". A type 2 excludes note indicates that the condition excluded is not part of the condition it is excluded from but a patient may have both conditions at the same time. When a type 2 excludes note appears under a code it is acceptable to use both the code (G24) and the excluded code together.

    Diseases of the nervous system
Clinical Information
  • A disease characterized by abnormal involuntary movements of muscles
  • Abnormal involuntary motor processes that occur due to underlying disease processes.
  • Abnormal involuntary movements which primarily affect the extremities, trunk, or jaw that occur as a manifestation of an underlying disease process. Conditions which feature recurrent or persistent episodes of dyskinesia as a primary manifestation of disease may be referred to as dyskinesia syndromes (see movement disorders). Dyskinesias are also a relatively common manifestation of basal ganglia diseases.
  • Acquired and inherited conditions that feature dystonia as a primary manifestation of disease. These disorders are generally divided into generalized dystonias (e.g., dystonia musculorum deformans) and focal dystonias (e.g., writer's cramp). They are also classified by patterns of inheritance and by age of onset.
  • Difficulty moving; distortion or impairment of voluntary movement, as in tic, spasm, or myoclonus.
  • Dystonia is a movement disorder which causes involuntary contractions of your muscles. These contractions result in twisting and repetitive movements. Sometimes they are painful. Dystonia can affect just one muscle, a group of muscles or all of your muscles. Symptoms can include tremors, voice problems or a dragging foot. Symptoms often start in childhood. They can also start in the late teens or early adulthood. Some cases worsen over time. Others are mild. Some people inherit dystonia. Others have it because of another disease. Either way, researchers think that a problem in the part of the brain that handles messages about muscle contractions might cause dystonia. There is no cure. Instead, doctors use medicines, surgery, physical therapy and other treatments to reduce or eliminate muscle spasms and pain. national institute of neurological disorders and stroke
  • Inherited condition that disables body movement due to abnormal muscle contraction and twisting distorted postures.
  • Syndrome dominated by involuntary, sustained or spasmodic, patterned, and repetitive muscle contractions; frequently causing twisting, flexing or extending, and squeezing movements or abnormal postures.
