Section 411.555 - Can the EN keep the milestone and outcome payments even if the beneficiary does not achieve all outcome months?(a) Yes. The EN (or State VR agency acting as an EN) can keep each milestone and outcome payment for which the EN (or State VR agency acting as an EN) is eligible, even though the title II beneficiary does not achieve all 36 outcome months or the title XVI beneficiary does not achieve all 60 outcome months.(b) Except as provided in paragraph (c) of this section, payments which we make or deny to an EN (or a State VR agency acting as an EN) may be subject to adjustment (including recovery, as appropriate) if we determine that more or less than the correct amount was paid. This may happen, for example, because we determine that the payment determination was in error or because of an allocation of payment under § 411.560 .(c) If we determine that an overpayment or underpayment to an EN has occurred, we will notify the EN (or State VR agency acting as an EN) of the adjustment. We will not seek an adjustment if a determination or decision about a beneficiary's right to benefits causes an overpayment to the EN. Any dispute which the EN (or State VR agency) has regarding the adjustment may be resolved under the rules in § 411.590(a) and (b) .
