CO-134 Denial Code: Technical fees removed from charges
The payer stripped the technical component — the mirror of CO-89; the TC belongs on a different claim or wasn't payable to you.
Why CO-134 happens
- ●Global service billed where only the professional component was payable
- ●TC payable to the facility, not the practitioner
