What is Pecos?

PECOS stands for Provider Enrollment, Chain, and Ownership System. It is an online system maintained by the Centers for Medicare & Medicaid Services (CMS) that allows healthcare providers and suppliers to enroll, update, and manage their Medicare enrollment information. PECOS is essential for providers who want to bill Medicare for services and helps streamline the enrollment process. It also helps CMS track the ownership and control information of providers and suppliers to prevent fraud and abuse.
