Version 2023
ICD-10:G23
Short Description:Other degenerative diseases of basal ganglia
Long Description:Other degenerative diseases of basal ganglia
Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Diseases of the nervous system (G00–G99)
    • Extrapyramidal and movement disorders (G20-G26)
      • Other degenerative diseases of basal ganglia (G23)

G23 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of other degenerative diseases of basal ganglia. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Other degenerative diseases of basal ganglia

Non-specific codes like G23 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for other degenerative diseases of basal ganglia:

  • BILLABLE CODE - Use G23.0 for Hallervorden-Spatz disease
  • BILLABLE CODE - Use G23.1 for Progressive supranuclear ophthalmoplegia [Steele-Richardson-Olszewski]
  • BILLABLE CODE - Use G23.2 for Striatonigral degeneration
  • BILLABLE CODE - Use G23.8 for Other specified degenerative diseases of basal ganglia
  • BILLABLE CODE - Use G23.9 for Degenerative disease of basal ganglia, unspecified

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 coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Brain Diseases

The brain is the control center of the body. It controls thoughts, memory, speech, and movement. It regulates the function of many organs. When the brain is healthy, it works quickly and automatically. However, when problems occur, the results can be devastating.

Inflammation in the brain can lead to problems such as vision loss, weakness and paralysis. Loss of brain cells, which happens if you suffer a stroke, can affect your ability to think clearly. Brain tumors can also press on nerves and affect brain function. Some brain diseases are genetic. And we do not know what causes some brain diseases, such as Alzheimer's disease.

The symptoms of brain diseases vary widely depending on the specific problem. In some cases, damage is permanent. In other cases, treatments such as surgery, medicines, or physical therapy can correct the source of the problem or improve symptoms.
