Social Security has published a final rule in the Federal Register. Here is Social Security's summary:
These rules amend our title II regulations to explicitly provide that we apply an underpayment due an individual to reduce an overpayment to that individual in certain cases. Our title XVI regulations already state this policy. Additionally, these rules reflect our procedures for collecting overpayments when a payment of more than the correct amount is made to a representative payee on behalf of a beneficiary after the beneficiary's death. These rules clarify that we collect overpayments in this situation from only the representative payee or his estate but not from the representative payee's spouse or from the spouse's estate.
