G24.01 vs G24.4
G24.01 (Drug induced subacute dyskinesia) compared with G24.4 (Idiopathic orofacial dystonia), from the official CMS tabular data. Do not report these codes together: the official tabular list marks them Excludes1.
Can these codes be reported together?
No — do not report together. G24.4 carries an Excludes1 note covering G24.01: “drug induced orofacial dyskinesia (G24.01)”
Sole exception: when the two conditions are documented as unrelated to each other (ICD-10-CM Official Guidelines, Section I.A.12.a).
