CO-B15 Denial Code: Required qualifying service not received
This service requires that a qualifying service/procedure be received and covered, and it was not identified on this claim.
Why CO-B15 happens
- ●Add-on code billed without its primary procedure
- ●Qualifying service billed on a separate claim or by another provider
How to fix a CO-B15 denial
- 1
Bill the add-on code on the same claim as its primary code
- 2
Resubmit with a corrected claim linking the qualifying service
How to prevent it
Edit for add-on code/primary code pairing in claim scrubbing.
