Where on the HCFA / CMS 1500 do you put resubmission codes?
Box 22 is where resubmission
codes are entered on the CMS-1500 form. This box is also where the Original
Reference Number of the previously submitted claim is entered.
Elaboration:
- Box 22:
Resubmission Code/Original Ref. No.
This field is specifically
designed to indicate whether a claim is a resubmission, correction, or
replacement of a prior claim and to include the original claim number.
When resubmitting a claim,
enter the appropriate code on the left-hand side of Box 22. Common codes
include:
6: Corrected Claim
7: Replacement of Prior
Claim
8: Void/Cancel of Prior
Claim
- Original
Reference Number:
Box 22 should also include
the original claim number assigned by the insurance payer. This helps the payer
identify the original claim and properly process the resubmission or
correction.
Below is an example of a
resubmission code for a corrected claim, along with the original claim number
assigned by the insurance payer
