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

G32.8 is the ICD-10-CM diagnosis code for other specified degenerative disorders of nervous system in diseases classified elsewhere. It belongs to category G32 (other degenerative disorders of nervous system in diseases classified elsewhere), block G30-G32 (other degenerative diseases of the nervous system) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within G32, choose G32.8 (Other specified degenerative disorders of nervous system in diseases classified elsewhere) only when documentation doesn't support a more specific option: subacute combined degeneration of spinal cord in diseases classified elsewhere (G32.0).

To report this condition, pick the subcode that matches the documentation: G32.81 (elsewhere) and G32.89 (elsewhere).

Don't report G32.8 together with the conditions in its Excludes1 note: superior hemorrhagic polioencephalitis [Wernicke's encephalopathy] (E51.2).

Code first underlying disease, such as: amyloidosis cerebral degeneration (E85.-), cerebral degeneration (due to) hypothyroidism (E00.0-E03.9), cerebral degeneration (due to) neoplasm (C00-D49) and cerebral degeneration (due to) vitamin B deficiency, except thiamine (E52-E53.-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
