System Issue Resolved for Electronic Void/Replace Block-Billed Claims

December 9, 2020

The Department of Health Care Services (DHCS) announced in November 2020 that outpatient and medical providers were receiving a Computer Media Claims (CMC) reject error message “001” (CMC replacement/void claim cannot be billed with multiple claims), when submitting a block-billed or from-through electronic claim and using frequency code “7” (replacement of prior claim) or claim frequency code “8” (void) on previously paid claims. The system issue has now been resolved.
