What This Code Means
G24.0 is the ICD-10-CM diagnosis code for drug induced dystonia. G24.0 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering extrapyramidal and movement disorders (g20-g26).
Header codes like G24.0 cannot be reported on claims directly; they organize child codes that share clinical context. Coders should select the billable child code that matches the documented presentation and then verify its current source-backed HCC mapping. Do not infer a child code or risk adjustment value from the header alone.
HCC Buddy maintains structured V28 and V24 mapping, source-labeled coefficient references, and MEAT documentation criteria for G24.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
