About coding dyskinesia
The ICD-10-CM code for dyskinesia is G24.9 (Dystonia, unspecified). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on G24.9.
Within G24, choose G24.9 (unspecified) only when documentation doesn't support a more specific option: drug induced dystonia (G24.0), genetic torsion dystonia (G24.1), idiopathic nonfamilial dystonia (G24.2), Spasmodic torticollis (G24.3), idiopathic orofacial dystonia (G24.4), Blepharospasm (G24.5) and other dystonia (G24.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
