Internet-based PECOS

The CMS Provider Enrollment, Chain and Ownership System (PECOS) supports the Medicare Provider and Supplier enrollment process by allowing registered users to securely and electronically submit and manage Medicare enrollment information.

Why should I use Internet-based PECOS to submit my application versus paper? 

  • Faster than paper
  • Tailored application process means you only supply information relevant to your application
  • Control over your enrollment information
  • Easy to check the information for accuracy and update
  • Less time and money spent in completing the application
