The beneficiary or their representative may request an appeal on any service processed for them. Providers and Suppliers may appeal services for which assignment was accepted. For unassigned claims, providers/suppliers may act as the beneficiary's representative if the beneficiary signs an authorization statement (such as form CMS-1696). In addition, providers/suppliers may request a redetermination on an unassigned claim if Medicare B denied the service as not reasonable and necessary or the provider/supplier billed in excess of the Limiting Charge and the provider/supplier is required to refund any fees collected from the beneficiary.
