G32.8: Other specified degenerative disorders of nervous system in diseases classified elsewhere

Non-billable headerICD-10-CM

G32.8 is a non-billable header ICD-10-CM code for other specified degenerative disorders of nervous system in diseases classified elsewhere. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • superior hemorrhagic polioencephalitis [Wernicke's encephalopathy] (E51.2)

Code first

The underlying condition must be sequenced before this code.

  • underlying disease, such as:
  • amyloidosis cerebral degeneration (E85.-)

  • cerebral degeneration (due to) neoplasm (C00-D49)
  • cerebral degeneration (due to) vitamin B deficiency, except thiamine (E52-E53.-)
