What This Code Means
G24.3 is the ICD-10-CM diagnosis code for spasmodic torticollis. A condition causing involuntary twisting and turning of the neck, often resulting in the head being pulled to one side or rotated abnormally. G24.3 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).
G24.3 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Document the direction of head deviation and whether symptoms are constant or intermittent.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G24.3 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Document the direction of head deviation and whether symptoms are constant or intermittent
- •Note any associated pain, tremor, or functional limitations affecting daily activities
