Denial code · Contractual Obligation (CO)
CO-50 denial code
The payer says this service is not needed for this person's health in this case.
What the code means
Official meaning: These are non-covered services because this is not deemed a 'medical necessity' by the payer.
In plain words: The payer says this service is not needed for this person's health in this case.
The usual fix
Check the payer's rules for when this service counts as needed. If the record shows it was needed, send the record with an appeal where the payer allows that.
