CO-169 Denial Code: Alternate benefit provided
The payer paid under a different (usually cheaper) benefit than billed — classic in dental (amalgam rate for composite) and DME (standard vs deluxe).
Why CO-169 happens
- ●Plan's alternate-benefit clause substitutes the least-costly adequate treatment
How to fix a CO-169 denial
- 1
Bill the patient the difference if plan terms and your contract allow — verify first
- 2
Appeal with clinical justification if the billed service was the only appropriate option
How to prevent it
Discuss alternate-benefit clauses and cost differences with patients before treatment.
