What N572 means

For certain procedures, a payer may require extra, non-payable reporting codes on the claim, typically to capture data like the patient’s functional status or a quality measure. Each reporting code needs modifiers that add detail. N572 says those reporting lines, or their modifiers, were missing, so the procedure itself will not be paid until they are there.

It most often accompanies CARC 16 or CARC 4. The app’s curated combination with CARC B7 describes a different problem, a provider not certified for the procedure, so when you see CO-B7 with N572 verify credentialing as well.

Common causes

  • The reporting line was left off because the charge entry template did not prompt for it.
  • The reporting code was sent without its modifiers, or with modifiers that do not fit the code.
  • Reporting was sent only at the start of care when the payer also requires it at set intervals or at discharge.

How to fix it

  1. Check the payer’s policy for which reporting codes and modifiers the procedure requires.
  2. Confirm the documentation supports the reported status or measure.
  3. Submit a corrected claim with resubmission code 7 in box 22, adding the reporting lines and modifiers in box 24D.
  4. If CARC B7 is also present, check the rendering provider’s credentialing with the payer and resolve that before refiling. See provider enrollment denials.

How to prevent it

Tie the reporting requirement to the procedure in your billing system so the claim cannot be released without the reporting lines. Claims Validator can check claims before submission so missing required lines are caught early.

Codes that may appear with N572

  • CO-16 (Claim/service lacks information or has submission/billing error(s).): The claim lacks information; N572 names the missing reporting codes and modifiers.
  • CO-4 (The procedure code is inconsistent with the modifier used.): The procedure code is inconsistent with the modifiers used.
  • CO-B7 (This provider was not certified/eligible to be paid for this procedure/service on this date of service.): Some payers pair N572 with a provider eligibility denial for the procedure; check both issues.
  • N566 (Alert: This procedure code requires functional reporting.): The alert version: future claims for this procedure need functional reporting.
  • N565 (Alert: This non-payable reporting code requires a modifier.): The alert that a reporting code needs a modifier.
  • CO-246 (This non-payable code is for required reporting only.): Non-payable reporting codes are for required reporting only.

N572 FAQ

How is N572 different from N566?

N566 is a warning about future claims. N572 means this claim is not being paid until the reporting codes and modifiers are added.

What reporting codes are needed?

It depends on the payer and service. N572 was introduced with Medicare's therapy functional reporting, which used non-payable G-codes and severity modifiers, but other payers can apply it to their own reporting requirements.

Do I add the reporting code as a new line?

Usually yes, as a separate zero or nominal charge line on the same claim, with the required modifiers. Follow the payer's instructions for charge amounts.
