What This Code Means
G62.9 is the ICD-10-CM diagnosis code for polyneuropathy, unspecified. Nerve damage affecting multiple nerves where the underlying cause has not been identified or documented. G62.9 sits in the ICD-10-CM chapter for diseases of the nervous system (g00-g99), within the section covering polyneuropathies and other disorders of the peripheral nervous system (g60-g65).
G62.9 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 a default code; use only when the specific type or cause of polyneuropathy cannot be determined.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for G62.9 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •This is a default code; use only when the specific type or cause of polyneuropathy cannot be determined
