What N562 means

In NOA-based bundled payment pilots, the Notice of Admission and the claims that follow it must come from the same provider. The payer matches them using the provider number. N562 says the number on your claim is different from the number on the NOA it already processed, so it cannot attach the claim to the episode.

Think of it as a linking failure rather than a coverage decision. It usually appears alongside CARC 16 (submission or billing error).

Common causes

  • Different billing entities. The NOA was filed under one organization’s number and the claim under another, for example after a merger or a change of ownership.
  • A facility with multiple numbers filed the NOA under one location and the claim under another.
  • Keying errors on either document.
  • Enrollment changes between the NOA date and the claim date.

How to fix it

  1. Pull the processed NOA and the claim, and compare the provider identifiers.
  2. Decide which one is wrong. If the claim is wrong, correct it. If the NOA is wrong, ask the payer how to correct or cancel it.
  3. Resubmit the claim with the matching provider number. Use a replacement claim (resubmission code 7) if the original was processed, unless the payer asks for a new claim.
  4. Confirm the link by checking the next remittance for the episode.

How to prevent it

Assign one owner for each episode who files both the NOA and the claims under the same provider number. After any ownership or enrollment change, audit open episodes before claims go out. See provider enrollment denials for related identifier issues.

Codes that may appear with N562

  • CO-16 (Claim/service lacks information or has submission/billing error(s).): The claim has a submission or billing error; N562 names the provider number mismatch with the NOA.
  • CO-132 (Prearranged demonstration project adjustment.): Demonstration project adjustment, used in bundled payment pilots.
  • N560 (The pilot program requires an interim or final claim within 60 days of the Notice of Admission.): No interim or final claim arrived within 60 days of the NOA.
  • N568 (Alert: Initial payment based on the Notice of Admission (NOA) under the Bundled Payment Model IV initiative.): Initial payment was based on the NOA under a bundled payment model.
  • N521 (Mismatch between the submitted provider information and the provider information stored in our system.): A general mismatch between submitted provider information and the payer's records.

N562 FAQ

Which provider number must match?

The identifier the payer uses to link claims to the NOA, typically the billing provider's NPI or the payer-assigned provider number used on the notice. Compare both documents field by field.

What if the NOA itself was wrong?

Ask the payer how to correct or cancel the notice. Changing only the claim will not help if the NOA carries the wrong number.

Will fixing the number restore payment?

It allows the claim to link to the episode. Payment still depends on the program's other rules.
