CO-151 Denial Code: Payment adjusted — frequency of services
Payer deems the information submitted does not support this many/frequency of services.
Why CO-151 happens
- ●Units exceed Medically Unlikely Edits (MUE) limits
- ●Service billed more often than policy frequency allows
- ●Units keyed incorrectly
How to fix a CO-151 denial
- 1
Verify units against documentation and MUE limits
- 2
Correct unit errors and resubmit
- 3
Appeal with documentation if the frequency was medically necessary
How to prevent it
Add MUE and frequency edits to claim scrubbing rules.
