Which function do ZPICs NOT perform?

ZPICs, or Zone Program Integrity Contractors, are tasked mainly with protecting Medicare funds and ensuring that healthcare providers comply with regulations. Their responsibilities include investigating potential fraud and abuse, as well as proactive identification of fraudulent activities within their designated service areas.

The function of proactively identifying fraud incidents outside their service area does not fall under ZPICs' responsibilities. Each ZPIC only operates within the boundaries of their specific jurisdiction to effectively identify and address issues relevant to that area. This localized focus allows them to effectively investigate and manage fraud cases pertinent to the providers they oversee.

In contrast, taking action on fraudulent cases and conducting audits of healthcare providers within their service area are fundamental duties of ZPICs. Additionally, they are responsible for actively monitoring and seeking out fraud incidents where they have jurisdiction. Thus, the correct choice recognizes that ZPICs do not extend their operational scope to proactive identification of fraud incidents outside their designated areas.
