An Advance Beneficiary Notice (ABN) is a notice a provider should give you before you receive a service if, based on Medicare coverage rules, your provider has reason to believe Medicare will not pay for the service. The ABN allows you to decide whether to get the care in question and to accept financial responsibility for the service (pay for the service out-of-pocket) if Medicare denies payment.
