42 CFR § 405.972 - Withdrawal or dismissal of a request for reconsideration or review of a contractor's dismissal of a request for redetermination.
(a) Withdrawing a request. An appellant that files a request for reconsideration may withdraw its request by filing a written and signed request for withdrawal. The request for withdrawal must -
(2) Be received in the QIC's mailroom before the reconsideration is issued.
(3) When the party fails to file the reconsideration request in accordance with the timeframes established in § 405.962, or fails to file the request for review of a contractor's dismissal of a redetermination request in accordance with the timeframes established in § 405.974(b)(1);
(i) The beneficiary's surviving spouse or estate has no remaining financial interest in the case. In deciding this issue, the QIC considers if the surviving spouse or estate remains liable for the services for which payment was denied or a Medicare contractor held the beneficiary liable for subsequent similar services under the limitation on liability provisions based on the denial of payment for services at issue;
(ii) No other individual or entity with a financial interest in the case wishes to pursue the appeal; and
(5) When a party filing for the reconsideration submits a written request of withdrawal to the QIC and satisfies the criteria set forth in paragraph (a) of this section before the reconsideration has been issued; or
(6) When the contractor has not issued a redetermination on the initial determination for which a reconsideration is sought.
(c) Notice of dismissal. A QIC mails or otherwise transmits written notice of the dismissal of the reconsideration request to the parties at their last known addresses. The notice states that there is a right to request that the contractor vacate the dismissal action. The appeal will proceed with respect to any other parties that have filed a timely request for reconsideration.
(e) Effect of dismissal. The dismissal of a request for reconsideration is binding unless it is modified or reversed by an ALJ or attorney adjudicator under § 405.1004 or vacated under paragraph (d) of this section. The dismissal of a request for review of a contractor's dismissal of a redetermination request is binding and not subject to further review unless vacated under paragraph (d) of this section.
