Denial Code CO-151: Description, Meaning and How to Fix It
The billed frequency or quantity exceeds what the payer allows or the documentation supports.
Official description
Payment adjusted because the payer deems the information submitted does not support this many/frequency of services.
Common cause
Units/frequency billed exceed payer limits or documentation.
How to fix it
Verify units against documentation and payer frequency limits, correct if needed, and appeal with records if the frequency was justified.
