CO-5 Denial Code: Procedure code inconsistent with place of service
The procedure code/type of bill is inconsistent with the place of service.
Why CO-5 happens
- ●Facility-only code billed with an office POS (or vice versa)
- ●Wrong POS code keyed on the claim
- ●Telehealth service without the telehealth POS/modifier
How to fix a CO-5 denial
- 1
Verify where the service was actually rendered
- 2
Correct the POS code or the procedure code to match
- 3
Resubmit as a corrected claim
How to prevent it
Add POS-to-CPT compatibility edits in claim scrubbing.
