What Does CO-P11 Mean?

When paired with Group Code CO, the P&C claim cannot be finalized due to litigation. This is not appealable through normal channels. Redirect to health insurance.

CARC P11 is closely related to P10 but has a subtle distinction: while P10 indicates payment was reduced to zero, P11 specifically indicates the P&C claim disposition itself is pending because of litigation. The medical claim is in limbo because the underlying P&C claim has not been resolved due to ongoing legal proceedings — liability may still be in dispute, a previous determination is being appealed, or the P&C case itself is being litigated.

The practical effect is the same as P10: the carrier cannot process the medical claim until the legal matter is resolved. Redirect billing to health insurance in the interim.
