Is R94.110 an HCC code?
No. R94.110 is a billable ICD-10-CM code but does not map to any HCC category in V28, V24, ESRD, or RxHCC.
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
R94.110 is the ICD-10-CM diagnosis code for abnormal electro-oculogram [eog]. An EOG (eye movement test) shows abnormal electrical activity related to eye movements. R94.110 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).
R94.110 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.
EOG measures the electrical potential generated by eye movements; document which eye(s) showed abnormality if applicable.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R94.110 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
