Void claims now appear on remittance advice with original claims

In June 2024, we changed how we process your void claims (claims submitted to cancel a previous claim) to align with industry standards, for both UB-04 and HCFA-1500 claim forms.

Previously, we would close the void claim, and you would see just one claim adjustment on your remittance advice (RA) for the original claim’s payment recovery. Now, you’ll see adjustments for both the void claim and original claim as follows:

RA type	Adjustment codes you'll see
Paper RA	Void claim (denial): K49 – Claim has been cancelled or voided Original claim (payment recovery): OX6 – Charge billed in error
Electronic RA	Void claim (denial): CARC 18 – Exact duplicate claim/service Original claim (payment recovery): CARC 16 (Claim/service lacks information or has submission/billing error(s)) and RARC M79 (Missing/incomplete/invalid charge)

Please note, we won’t process appeals on void claim denials.
