Denial Codes / CARC 109
Denial Code CARC 109: Claim Not Covered by This Payer or Contractor
CARC 109 means this payer or contractor is not responsible for the claim, usually because it went to the wrong payer, the wrong plan, or in the wrong coordination-of-benefits order. It is fully recoverable, because the money is real and simply needs to reach the correct payer.
What this denial means
The payer is saying it is not the responsible party for this claim, so it will not adjudicate it. It is a routing denial, not a coverage decision.
Why it happens
The claim went to the wrong payer entirely, to a terminated plan, or to a secondary payer before the primary processed it. Coordination-of-benefits order errors are the most common cause: the claim reached a real payer, just not the one responsible first.
The appeal angle that works
Identify the correct responsible payer and the right coordination-of-benefits order, then submit to the correct payer, attaching the primary’s explanation of benefits if this is a secondary claim. There is nothing to appeal with the wrong payer; the recovery is routing the claim to the right one before any filing deadline lapses.
Questions
What does it mean when a claim is not covered by this payer?
It means the claim reached the wrong payer or the wrong plan, or went out of coordination-of-benefits order. The service may be perfectly payable; it just needs to go to the responsible payer, with the primary’s explanation of benefits attached if it is a secondary claim.
