What This Code Means
G25.0 is the ICD-10-CM diagnosis code for essential tremor. A common tremor that occurs when muscles are actively used, such as holding objects or maintaining a posture, without an identified underlying disease. G25.0 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).
G25.0 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.
Confirm this is primary essential tremor and not secondary to medications, hyperthyroidism, or other conditions.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G25.0 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Confirm this is primary essential tremor and not secondary to medications, hyperthyroidism, or other conditions
- •Document affected body parts (hands, head, voice) and severity
Excludes 1, Do NOT code together
- tremor NOS (R25.1)
