The Processing Center (PC) must initiate an SSA-e4345, Record of Manual Title II Offset
Computation, to the field office (FO) to request a recomputation of the title II offset
when either of the following title II postentitlement (PE) events occurs:
The month of entitlement to title II benefits changes to an earlier month, which changes
the beginning date of the offset period; or,
We lower the title II benefit used in a prior offset computation, which results in
a title II overpayment.
NOTE: Whenever a processing error results in an incorrect offset computation, a recomputation
of the offset is necessary. For more information about when to do a recomputation,
see SM 01320.400. For information about recomputing windfall offset when the title
II date of entitlement (DOE) changes, see GN 02610.050B.
