Is R25.0 an HCC code?
No. R25.0 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
R25.0 is the ICD-10-CM diagnosis code for abnormal head movements. Involuntary or abnormal movements of the head, such as nodding, shaking, or jerking motions. R25.0 sits in the ICD-10-CM chapter for symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (r00-r99), within the section covering symptoms and signs involving the nervous and musculoskeletal systems (r25-r29).
R25.0 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.
Determine if movements are rhythmic (tremor) or irregular (dystonia, tics) for potential additional coding.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R25.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Determine if movements are rhythmic (tremor) or irregular (dystonia, tics) for potential additional coding
- •Investigate neurological causes such as Parkinson's disease or essential tremor that may require separate codes
