Check my letter freeWhat CO-45 means
The charge is above the amount the plan agreed to pay the provider. It is not a denial.
CO means contractual obligation: under its contract, the provider is usually responsible for this amount, so an in-network provider generally should not bill you for it.
What to do
An in-network provider generally cannot bill you for this difference. If you get a bill for it, ask the provider to remove it.
