What N618 means

N618 tells you this claim isn’t finished. The patient owes premiums, and the payer has promised to reprocess the claim on its own once they are paid. It is common with CARC 257 or 277 during Marketplace grace periods.

What to do

Don’t resubmit. Resending can trigger a duplicate claim denial.
Tell the patient that paying the premium will let the claim be paid.
Set a follow-up date after the grace period ends and watch your remittances for the reprocessed claim.
Bill the patient according to your policy only if the claim is finally denied.

N618 FAQ

Do I need to resubmit?

No. The alert says reprocessing is automatic once premiums are paid. Resubmitting may create a duplicate.

How will I know it was reprocessed?

A later remittance will show the claim again with a new outcome. Check your ERA for it after the patient reports paying.

What if the patient never pays?

The claim will stay unpaid or be denied. Follow your financial policy for billing the patient.
