The DISCO program retrieves online earnings, NUMIDENT, and Supplemental Security Record
            data to produce DIB insured status calculations. DISCO determines whether a claimant
            is insured for title II benefits. The Disability Wizard Quality Management Tool (DIBwiz
            QMT) helps to establish proper EODs (Established Onset Dates) and to identify prior
            entitlement and title II (T2) insured status. The FO may use either of these tools
            to assess key technical entitlement issues, such as insured status, earnings, and
            prior filings.
         
         Additional information on DISCO, DIBwiz, and other tools are available on the toolbar.
         When coding foreign QCs in the DISCO program use the number “8”. The number “1” is
            used to code US QCs only.
         
         For each year in which there is a U.S. and or a foreign QC: 
         
            - 
               
                  • 
                     Display a U.S. QC as “1.” 
 
 
- 
               
                  • 
                     Display a foreign QC as “8.” • Display no QC as “N.” 
 
 
- 
               
                  • 
                     Show QCs in proper order. 
 
 
Example: There are US QC’s for the year 1969 through the year 1999 and Foreign
               QC’s for the year 2000 through the second quarter of the year 2019. 
         
         The following alerts have been added to the DISCO program to reflect the use of
               foreign QCs.
         This alert will appear when the Modify QC pattern contains the number (8):
         
            - 
               
                  • 
                     Totalization QCs involved refer to: GN 01703.100 Crediting Foreign Coverage, GN 01703.110 How To Document Insured Status Decisions GN 01701.140 Entitlement to Hospital Insurance (HI) in Totalization Claims.
                      
 
 
This alert will appear when the Modify QC pattern contains the number (8) and MQGE
            is selected:
         
         
            - 
               
                  • 
                     MQGE selected and Totalization QCs potentially involved. Totalization QCs cannot be
                        used to establish premium-free HI refer to: GN 01701.140 Entitlement to Hospital Insurance (HI) in Totalization Claims, GN 01701.135 Totalization Benefits Payable by the United States.
                      
 
 
This alert will appear whenever there is a totalization segment on the MBR:
         
            - 
               
                  • 
                     Totalization data is present on MBR refer to: SM 00510.092 Totalization Data Line.
