What This Code Means
R94.118 is the ICD-10-CM diagnosis code for abnormal results of other function studies of eye. Test results showing abnormal function of the eye, such as vision or eye movement tests that don't show normal results. R94.118 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).
R94.118 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 code when eye function studies (like visual field or ocular motility tests) are abnormal but the underlying cause hasn't been diagnosed yet.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for R94.118 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Use this code when eye function studies (like visual field or ocular motility tests) are abnormal but the underlying cause hasn't been diagnosed yet
- •Do not use this code if a specific eye disease diagnosis has been established; instead code the diagnosed condition
