What N571 means

Some payments are not made claim by claim. Certain incentive, bonus, or program payments are pooled and paid periodically by a separate payer or contractor. N571 tells you this service falls into that category: the amount will be paid quarterly by someone else, so it will not appear on this remittance.

What to do

Post the remittance as-is, and move the deferred amount to a tracked receivable rather than writing it off.
Note the expected paying entity and quarter.
Match quarterly payments to the claims they cover when they arrive. An ERA analysis helps spot deferred amounts that never got paid.

N571 FAQ

Should I write this amount off?

No. Leave it open and track it until the quarterly payment arrives from the other payer or contractor.

Who sends the quarterly payment?

The remittance or the payer's program guidance should identify it. If it doesn't, call the payer that issued N571.

What if the quarterly payment never arrives?

Contact the payer that sent N571 with the claim details and ask how to follow up with the paying entity.
