Develop each case for your office as shown below:
For those cases that appear to involve duplicate records on which payment has been
made on both records, check all pertinent FO records/files or contact the individual(s)
or representative payee to confirm that the two records pertain to the same individual.
Terminate the incorrect record using payment status code T20 (see SM 01305.001O.27.)
and include the correct SSN in the Multiple Social Security Number (M1) field. On
the correct record input the incorrect SSN from the T20 record in the (M1) field (see
SM 01301.665). Develop any overpayment.
NOTE: If the SSN on the T20 record was also issued to the individual through the enumeration
process, input the SSN to the MA field as well as the M1 field.
