Is G25.9 an HCC code?
No. G25.9 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
G25.9 is the ICD-10-CM diagnosis code for extrapyramidal and movement disorder, unspecified. A general category for movement and coordination disorders when the specific type cannot be determined or is not documented. G25.9 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).
G25.9 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.
This is the least specific code in the movement disorder category; query the provider for clarification on the type of movement disorder.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G25.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is the least specific code in the movement disorder category; query the provider for clarification on the type of movement disorder
