(a) General rule. The contractor mails, or otherwise transmits, written notice of the redetermination or dismissal to the parties to the redetermination at their last known addresses within 60 calendar days of the date the contractor receives a timely filed request for redetermination. (b) Exceptions. (1) If a contractor grants an appellant's request for an extension of the 120-day filing deadline made in accordance with §405.942(b), the 60-day decision-making time frame begins on the date the contractor receives the late-filed request for redetermination, or when the request for an extension is granted, whichever is later. (2) If a contractor receives from multiple parties timely requests for redetermination of a claim determination, consistent with §405.944(c), the contractor must issue a redetermination or dismissal within 60 days of the latest filed request.
