CO-147 fires when the payer has no negotiated rate on file for the provider or the service. The contract may have lapsed, may never have been loaded, or may not include the service billed.
What CO-147 means
Rate loading is an operational step separate from signing, and it fails quietly. A newly contracted provider whose rates were never loaded, a renewal that lapsed at a term boundary, or a service added to the practice that the existing schedule does not price all produce it. Nothing on the claim can fix it, and every claim will deny identically until the schedule is corrected — which makes provider relations, not appeals, the right destination.
Why CO-147 fires
- A newly contracted provider's rates were never loaded.
- The contract term lapsed and was not renewed in the system.
- The service is outside the schedule the contract loaded.
- A rate change was agreed and not implemented.
