About coding Oromandibular dystonia
The ICD-10-CM code for Oromandibular dystonia is G24.4 (Idiopathic orofacial dystonia). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on G24.4.
Within G24 (dystonia), G24.4 is specifically for idiopathic orofacial dystonia. Related codes cover drug induced dystonia (G24.0), genetic torsion dystonia (G24.1), idiopathic nonfamilial dystonia (G24.2), Spasmodic torticollis (G24.3), Blepharospasm (G24.5), other dystonia (G24.8) and unspecified (G24.9).
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.
