Plan Sponsors are required to coordinate individual retiree cost data within an application for the purpose of appropriately applying each individual retiree's Cost Threshold and Cost Limit. CMS' RDS Center understands that a situation may arise where individual retirees are associated with more than one Unique Benefit Option Identifier (UBOI) within one of a Plan Sponsor's applications and/or have costs reported by more than one Cost Reporter within the same RDS application. The RDS Program requires Plan Sponsors to coordinate an individual retiree's drug cost data within an application if the retiree is claimed under multiple UBOIs and/or is being claimed by multiple Cost Reporters for the same application.
For more information as well as examples of how to handle coordination of individual retiree cost data, refer to Coordination of Individual Retiree Cost Data.
