If the beneficiary’s record reflects an uncashed payment within the past 12 months,
SSA sends a notice to the beneficiary inquiring if the check was received and cashed.
If the beneficiary does not respond or indicates a cashed payment, take no further
action. SSA technicians will reissue payments or inquiry responses indicating payments
were not received and cashed see, Beneficiary/Recipient Contacts SSA Concerning a
Limited Payability Notice (Title II) GN 02401.905.
Treasury cancels the check in the 13th or 14th month and returns the credit back to
SSA in the 15th month after issue date of the check. This credit appears on the Payment
History Update System (PHUS) record in the form of an EVNT-169 UNNEG CK (Unnegotiated
check). See, Unnegotiated Check Events SM 00545.300.
