For alleged nonreceipt cases where SSA inputs a B-stop, the Department of the Treasury
                  issues a courtesy replacement check payment. If the original check is subsequently
                  cashed and no automated F-stop occurs on the courtesy replacement check, the Program
                  Service Center (PSC) will enter a manual F-stop action.
               
               The PSC receives a “PREPARE 1184 REACT” alert. The PSC will input a manual F-stop
                  action via the RSDHI using PESP input screens (MSOM RSDHI 002.005) or by using the
                  SSA-4510 Stop Payment Request Input Form (MSOM INTRANETMAMPSCDI 004.003) screen. For
                  PC processing instructions, see SM 00609.001B.2.
