What This Code Means
R94.128 is the ICD-10-CM diagnosis code for abnormal results of other function studies of ear and other special senses. Test results showing abnormal function of the ear or other sensory organs (taste, smell) that don't fit into more specific categories. R94.128 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).
R94.128 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 catch-all code for abnormal sensory function studies not classified elsewhere.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R94.128 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
