About G81

G81 is the ICD-10-CM diagnosis code for hemiplegia and hemiparesis. It belongs to block G80-G83 (cerebral palsy and other paralytic syndromes) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G81.0 (hemiplegia), G81.1 (hemiplegia) and G81.9 (unspecified).

Don't report G81 together with the conditions in its Excludes1 note: congenital cerebral palsy (G80.-) and hemiplegia and hemiparesis due to sequela of cerebrovascular disease (I69.05-, I69.15-, I69.25-, I69.35-, I69.85-, I69.95-).

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