Medicare Provider-Supplier Enrollment
This section is designed to provide Medicare enrollment information for providers, physicians, non-physician practitioners, and other suppliers. Please review the downloadable fact sheets below to learn more about Medicare provider and supplier enrollment.
CMS has established Internet-based Provider Enrollment, Chain and Ownership System (PECOS) as an alternative to the paper (CMS-855) enrollment process. Internet-based PECOS will allow physicians, non-physician practitioners and provider and supplier organizations to enroll, make a change in their Medicare enrollment, view their Medicare enrollment information on file with Medicare, or check on status of a Medicare enrollment application via the Internet. For more information about the Internet-based PECOS, please select the "Internet-based PECOS" link to the left.
For information regarding DMEPOS accreditation, Competitive Acquisition and surety bond information, please select the "DMEPOS Enrollment" link to the left.
