Reconsideration is a level of appeal in Medicare appeals processes. In Original Medicare (Part A and B), reconsideration is the second level, where your appeal is reviewed by a Qualified Independent Contractor (QIC). In Medicare Advantage, there are two reconsideration phases: the plan first reviews its denial of coverage or payment, and if it upholds the initial decision, the second level is reconsideration by the Independent Review Entity (IRE). In Part D plans, reconsideration is also the second level of appeal, conducted by the IRE.
