About G24

G24 is the ICD-10-CM diagnosis code for dystonia. It belongs to block G20-G26 (extrapyramidal and movement disorders) and chapter 6 (diseases of the nervous system). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: G24.0 (dystonia), G24.1 (dystonia), G24.2 (dystonia), G24.3 (torticollis), G24.4 (dystonia), G24.5 (Blepharospasm), G24.8 (dystonia) and G24.9 (unspecified).

The conditions in its Excludes2 note aren't part of G24, but may be coded alongside it if the patient has both: athetoid cerebral palsy (G80.3).

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