Whether the appeal remained live after the insurer's reconsideration decision of 1 May 2012.
The insurer validly reconsidered its earlier decision within the time allowed by Art. 53 para. 3 LPGA, and its new decision fully granted the appellant's request, so the case became moot.
An insurer may reconsider a decision or objection decision until its response is sent to the appellate authority. Since the respondent exercised that power within the extended response deadline and approved reimbursement, the appeal no longer had an object.
