CO-115 Denial Code: Procedure postponed, canceled, or delayed
The claim reflects a service that didn't happen as billed — the payer's records (often from auth or facility reporting) show postponement or cancellation.
Why CO-115 happens
- ●Charges released for a canceled procedure
- ●Modifier for discontinued procedure (73/74/53) missing when partially performed
How to fix a CO-115 denial
- 1
If partially performed, rebill with the correct discontinued-procedure modifier and op note
- 2
If not performed at all, void the claim
How to prevent it
Charge-capture reconciliation against the OR/procedure schedule before claims release.
