The Act requires a distinction between the "past-due benefits" amount for authorizing
            the fee under the fee agreement and the "past-due benefits payable" amount for notice
            purposes. The terms are not interchangeable.
         
         The first check we send to a claimant may include payment(s) for months after the
            month of effectuation and may include benefits or payments excluded from the definition
            of past-due benefits (see GN 03940.007B.). In these situations, the "past-due benefits" amount for calculating the fee under
            the fee agreement will differ from the "past-due benefits payable" amount (i.e., the
            amount of the retroactive payment the claimant receives).
         
         The following priority of payment order applies in Title XVI claims, and the Title
            XVI portion of concurrent Titles II and XVI claims, when there are past-due benefits
            and direct payment of a representative’s fee to either the representative or the entity
            if there is a valid assignment, as per GN 03920.021:
         
         
            - 
               
                  • 
                     We reimburse the State if IAR is involved. 
 
 
- 
               
                  • 
                     We pay the representative’s fee, to the extent that the withheld past-due benefits
                        permit, if the claimant’s appointed representative and the entity if there is a valid
                        assignment are eligible for direct payment and the representative has not waived a
                        fee or direct payment. In concurrent Titles II and XVI claims, we calculate the 25
                        percent amount available for possible direct payment after determining the amount
                        of Title XVI past-due benefits owed had the Title II benefits been paid timely. See
                        GN 02610.053, How to Process Title II Offset Cases When a Representative Fee Is Involved – Action
                        to Apply Offset.

                     If there is an outstanding prior overpayment, we recover the overpayment to the extent
                        possible.
