20 CFR §416.575

1. (a)We will begin collecting the overpayment balance by cross-program recovery from your current monthly title II and title VIII benefits no sooner than 30 calendar days after the date of the notice described in § 416.574. If within that 30-day period you pay us the full overpayment balance stated in the notice, we will not begin cross-program recovery.
2. (b)If within that 30-day period you ask us to review our determination that you still owe us this overpayment balance, we will not begin cross-program recovery from your current monthly benefits before we review the matter and notify you of our decision in writing.
3. (c)If within that 30-day period you ask us to withhold a different amount from your current monthly benefits than the amount stated in the notice, we will not begin cross-program recovery until we determine the amount we will withhold. This paragraph does not apply when § 416.573(d) applies.
4. (d)If within that 30-day period you ask us to waive recovery of the overpayment balance, we will not begin cross-program recovery from your current monthly benefits before we review the matter and notify you of our decision in writing. See §§ 416.550 through 416.556.
