What is it?
Box 22 is used to list the Original Reference Number for resubmitted/corrected claims. When resubmitting a claim, enter the appropriate frequency code:
- 6 - Corrected Claim
- 7 - Replacement of Prior Claim
- 8 - Void/Cancel Prior Claim
The Original Reference Number is assigned by the destination payer or receiver to indicate a previously submitted claim or encounter. This is also known as the Claim Reference Number or ICN.
This box is not intended for use with original claim submissions.
