ICD-10-CM Code G32.8

Other specified degenerative disorders of nervous system in diseases classified elsewhere

Version 2021 Non-Billable Code

Not Valid for Submission

G32.8 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of other specified degenerative disorders of nervous system in diseases classified elsewhere. The code is NOT valid for the year 2021 for the submission of HIPAA-covered transactions.

ICD-10:G32.8
Short Description:Oth degeneratv disord of nervous sys in dis classd elswhr
Long Description:Other specified degenerative disorders of nervous system in diseases classified elsewhere

Consider the following ICD-10 codes with a higher level of specificity:

  • G32.81 - Cerebellar ataxia in diseases classified elsewhere
  • G32.89 - Other specified degenerative disorders of nervous system in diseases classified elsewhere

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 G32.8:

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
  • underlying disease, such as:
  • amyloidosis cerebral degeneration E85
  • cerebral degeneration due to hypothyroidism E00.0 E03.9
  • cerebral degeneration due to neoplasm C00 D49
  • cerebral degeneration due to vitamin B deficiency, except thiamine E52 E53

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.
  • superior hemorrhagic polioencephalitis Wernicke's encephalopathy E51.2

Information for Patients


Degenerative Nerve Diseases

Also called: Neurodegenerative diseases

Degenerative nerve diseases affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Many of these diseases are genetic. Sometimes the cause is a medical condition such as alcoholism, a tumor, or a stroke. Other causes may include toxins, chemicals, and viruses. Sometimes the cause is not known.

Degenerative nerve diseases include

  • Alzheimer's disease
  • Amyotrophic lateral sclerosis
  • Friedreich's ataxia
  • Huntington's disease
  • Lewy body disease
  • Parkinson's disease
  • Spinal muscular atrophy

Degenerative nerve diseases can be serious or life-threatening. It depends on the type. Most of them have no cure. Treatments may help improve symptoms, relieve pain, and increase mobility.

  • Progressive multifocal leukoencephalopathy (Medical Encyclopedia)
