CO 97 denial code dental

On a dental remittance, code CO 97 means: The payer considers this service's value included in the payment for another service already adjudicated — a bundling adjustment. depends: check the facts first. Split by cause: a policy-stated bundle (buildup-into-crown without pre-op evidence of separate necessity) is close to unwinnable after the fact. A bundling edit misapplied to genuinely distinct services on different teeth or dates is winnable with charting that shows the separation.
