Internet-based Provider Enrollment, Chain and Ownership System for DMEPOS Suppliers

DMEPOS suppliers can use Internet-based PECOS to enroll, make a change in their enrollment record, view their Medicare enrollment information on file with Medicare and check on the status of a Medicare enrollment application via the Internet.

Using Internet-based PECOS
Before you begin to use Internet-based PECOS, you:

  • Should review the document titled, 'Internet-based PECOS -- Getting Started Guide for Suppliers of DMEPOS' to obtain access to Internet-based PECOS
  • Must obtain and designate a unique National Provider Identifier for each business/practice location that you are enrolling or have enrolled with the National Supplier Clearinghouse (NSC). Note: There is an exception for sole proprietorships.
  • Enter the 'legal business name' for the supplier of DMEPOS as it shown on the IRS documentation and on the National Plan and Provider Enumeration System (NPPES). Both PECOS and NPPES require the submission of the 'legal business name'.

Finalizing Submission and Responding to Development Request
After submitting an enrollment application via Internet-based PECOS, you:

  • Must either E-sign certification statements and upload other documents requiring a signature or print, sign and date (blue ink recommend) the certification statement(s) and mail the certification statement(s) and supporting documentation to the NSC within seven days. The NSC will not begin to process your enrollment application until it receives a signed and dated certification statement.  
  • May be asked to make corrections or submit additional documents by the NSC. In order for your application to be processed, you must submit this information promptly.

Pending paper enrollment application: If a DMEPOS supplier has a pending paper enrollment application, the supplier should not submit an Internet-based PECOS enrollment application for the same enrollment or change of information.

More information:  For more information about Internet-based PECOS, including contact information for the External User Services (EUS) help desk, go to CMS' website and select the 'Internet-based PECOS' tab on the left side of screen. The EUS help desk provides assistance to providers and suppliers if they encounter an application navigation or systems problem with Internet-based PECOS.
