PECOS Search

What is PECOS?

PECOS stands for the Provider Enrollment and Chain/Ownership System. It was created by CMS as an electronic portal for Medicare enrollment of physicians, non-physician practitioners, and provider and supplier organizations.

Even though some providers are enrolled in Medicare, their enrollment records might not be in PECOS. If they have not sent in a Medicare application to report any changes to their Medicare enrollment information within the past 5 years, they probably do not have an enrollment record in PECOS.
