A case may involve a Clerical Error and a Processing Error. As a result, part of the
case is subject to the rules of administrative finality and part of the case is not.
Depending on the details of each case, see GN 04010.010A through GN 04010.010D to determine necessary actions.
EXAMPLE: The CS made an incorrect computation of the primary insurance amount, determined a RIB of $106.50, and put
that incorrect amount on the award form; the correct amount is $98.50. In processing the case, the BA incorrectly paid a monthly rate of $102.50.
If the affirmative action in writing is within four years of the date of the notice of the initial determination (GN 04010.010C, step 4, first bullet) SSA can reopen and correct the CS's incorrect determination
from $106.50 to $98.50 based on Clerical Error. If SSA does not conclude its investigation
and revise its determination within six months after the investigation began (i.e.,
the affirmative action in writing date), then SSA must show it diligently pursued
the investigation since the correction is unfavorable to the beneficiary, per GN 04001.060.
If the affirmative action in writing is after four years from the date of the notice of the initial determination SSA cannot reopen and correct the CS's incorrect determination of $106.50
to $98.50 because the correction would be unfavorable to the beneficiary (i.e., the
claimant would receive less money). Therefore, $106.50 is the benefit amount SSA is
legally required to pay. Even though SSA cannot fix the CS's error in this scenario,
SSA can still correct the BA's Processing Error (GN 04010.010D) and increase the $102.50 to $106.50, effective with the first month of entitlement.
This principle applies regardless of whether the notice showed a correct or incorrect
