About G81.1
G81.1 is the ICD-10-CM diagnosis code for spastic hemiplegia. It belongs to category G81 (hemiplegia and hemiparesis), 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 5 subcodes must be used instead.
Within G81 (hemiplegia and hemiparesis), G81.1 is specifically for spastic hemiplegia. Related codes cover flaccid hemiplegia (G81.0) and hemiplegia, unspecified (G81.9).
To report this condition, pick the subcode that matches the documentation: G81.10 (affecting unspecified side), G81.11 (affecting right dominant side), G81.12 (affecting left dominant side), G81.13 (affecting right nondominant side) and G81.14 (affecting left nondominant side).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
