About coding orofacial idiopathic dystonia
The ICD-10-CM code for orofacial idiopathic dystonia is G24.4 (Idiopathic orofacial dystonia).
Within G24 (dystonia), G24.4 is specifically for idiopathic orofacial dystonia.

Don't report G24.4 together with the conditions in its Excludes1 note: drug induced orofacial dyskinesia (G24.01).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
