About G32

G32 is the ICD-10-CM diagnosis code for other degenerative disorders of nervous system in diseases classified elsewhere. It belongs to 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.

To report this condition, pick the subcode that matches the documentation: G32.0 (elsewhere) and G32.8 (elsewhere).

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