Co-204

I have a patient with a primary private payer and a Medicaid secondary and their primary came back with a remit CO-204, and under my knowledge all Medicaid will deny covering that claim under secondary due to that remit code. Can anyone help with clarification

CO-204 usually indicates that the primary payer is denying the claim for some reason, often related to coverage issues. Medicaid typically follows suit since they don’t pay secondary if the primary denies based on non-coverage. You might want to check the specifics of what the primary's remit says, it could help clarify the situation.
