R94.130 is a billable, specific ICD-10-CM code for abnormal response to nerve stimulation, unspecified. It is valid for submission on a claim.

Risk adjustment

R94.130 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
