Other Eye Disorders – Other Visual Disturbances
VEHSS identifies the annual prevalence of diagnosed Other Visual Disturbances based on the presence of International Classification of Diseases(ICD)-9 and ICD-10 codes in patient claims or electronic health record (EHR) systems. Patients with one or more diagnosis codes associated with a VEHSS subgroup are assigned to that subgroup. Diagnosis codes may be primary or secondary. Only one instance of a diagnosis code is required for assignment to the subgroup. Note that diagnosis codes in claims data are intended for billing purposes. Codes may not be present in cases where diagnosis codes are not required to justify payment. Diagnosed prevalence will also not identify any undiagnosed conditions, will not include patients not covered by the insurer, and will not identify prevalence among patients without a visit in the calendar year of data.
