CO-45Contractual Adjustment
Charges exceed the allowed amount
What this code means
Your provider billed more than what your insurer has agreed to pay for this service. If your provider is in-network, you cannot be billed for the difference.
What to do next
If your provider is in-network, you owe only your plan cost-sharing. You are not responsible for the difference between billed and allowed amounts. Contact your insurer if the provider attempts to bill you for the balance.
