What This Code Means
R94.120 is the ICD-10-CM diagnosis code for abnormal auditory function study. Hearing test results that show abnormal function, indicating possible hearing loss or other auditory problems. R94.120 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).
R94.120 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 code is for abnormal audiometry or hearing test results without a confirmed diagnosis of hearing loss.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R94.120 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
