A Remittance Advice (RA) is a notice of payments and adjustments sent to providers, billers, and suppliers. After a claim has been received and processed, a Medicare contractor produces the RA, which may serve as a companion to a claim payment(s) or as an explanation when there is no payment.
Remittance Advice should include some or all of the following information: 1  Payer Paid Amount: the dollar amount paid by the payer. 2  Approved Amount: the approved amount equals the amount for the total claim that was approved by the payer. 3  Allowed Amount: the allowed amount equals the amount for the total claim that was allowed by the payer.
