A wrong-payer denial is a claim denied because a different payer is responsible, often a behavioral-health company that administers the plan's mental health benefits.

Why it happens

Many health plans carve out behavioral health to a separate administrator. Claims sent to the medical plan come back denied, and the practice has a limited time to send them to the right one.
