MedImpact member data/pharmacy claims linkage issue. The member data carrier specific unique member id (ME107) and pharmacy claims carrier specific unique member id (PC107) cannot be used to link member data to pharmacy claims at this time. The carrier specific unique member ID provided by the system producing the member data does not align with the carrier specific unique member ID on the system producing the pharmacy claim records. Work around: It is possible to use the pharmacy claims for cost and utilization analyses or other analyses that do not require enrollment information. MedImpact is a new submitter therefore this issue is applicable to data requests pulled after July 2020. |
