What This Code Means
R94.130 is the ICD-10-CM diagnosis code for abnormal response to nerve stimulation, unspecified. Nerve stimulation tests that show abnormal results, but the specific type of abnormality hasn't been identified. R94.130 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 abnormal findings on diagnostic imaging and in function studies, without diagnosis (r90-r94).
R94.130 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.
Use this unspecified code only when the type of nerve stimulation abnormality is not documented.
