The Disability Determination Services (DDS) may at times receive a case from the Field
            Office (FO) for processing while another claim type is still pending further FO development
            or has not been identified for application. The DDS receives the subsequent claim
            while the original case is in process at some level. The original case can still be
            at the DDS or at the review component, or cleared to the FO for effectuation. Any
            claim under the same Electronic Disability Collect System (EDCS) filing are members
            of a concurrent case.
         
         “Split samples” occur when all claims filed in a concurrent case do not arrive in
            the quality review case processing system at the same time. Specifically, this arises
            when one or more of the claims in a concurrent case are sampled (i.e., the claim(s)
            that the FO and the adjudicating component processed correctly), but the other non-sample
            claim(s) is still pending in the FO, adjudicating component, or another review component.
            Thus, the claims become split.
         
         EXAMPLES:
         
            - 
               
                  • 
                     The FO does not process the mainframe (i.e., Modernized Claims System (MCS), Modernized
                        Supplemental Security Income Claims System (MSSICS)) or EDCS case transfers for one
                        or more of the concurrent claims in the case; or

                  • 
                     The adjudicating component does not properly process and transfer one or more of the
                        concurrent claims in a case (e.g., the adjudicating component does not clear both
                        claims in a concurrent Title II/Title XVI case at the same time). The review component
                        encounters this situation most often.
