N547 Remark Code: Claim Was Already Voided

N547 means a refund request, submitted as a void or cancel using claim frequency type code 8, was already processed for this claim. The payer will not process another void, and later corrections to the original claim cannot be applied because it has been cancelled.

What N547 means

A void claim, also called a cancel and identified with frequency type code 8, tells the payer to reverse a claim it previously processed. Any payment on the original is taken back, typically through a recoupment on a later remittance. X12 calls this a refund request in the remark’s wording.

N547 says that has already happened for this claim. The payer is rejecting a later transaction that conflicts with it, most often a second void or a corrected claim (frequency code 7) that points to the claim already cancelled.

Common causes

  • A void was sent twice, for example once electronically and once on paper.
  • A corrected claim was sent after the void, referencing the cancelled claim number.
  • Staff sent a void and then a refund check for the same overpayment.
  • A billing system automatically regenerated a void during reprocessing.

How to fix it

  1. Review the claim history on the payer’s portal or remittances: when the void processed and whether funds were recouped.
  2. Stop duplicate refunds. If you also mailed a refund check, contact the payer to reconcile.
  3. Submit a new original claim if services still need to be billed, since there is no active claim left to correct.
  4. Watch filing limits for the new claim, and keep proof of the original submission dates.
  5. Update your account to reflect the void and any recoupment.

How to prevent it

Use one method, electronic void or refund check, per overpayment, and record which was used. The duplicate claims guide covers how resubmission and frequency codes interact.

N547 FAQ

What is frequency code 8?

Claim frequency code 8 means void or cancel of a prior claim. On a CMS-1500 it is reported in box 22 with the original claim number, and electronically in the claim frequency field.

I need to bill the services again. What should I send?

Since the original was voided, submit a new original claim for the services, not a replacement. Check the payer's instructions and filing limits.

Why was my second void rejected?

The claim was already cancelled, so there is nothing left to void. If you are trying to return money, confirm whether the first void already recouped it.
