Provider Medicare Enrollment: The PECOS System


The Provider Enrollment, Chain and Ownership System (PECOS) is an alternative to paper applications when health care providers and suppliers want to enroll in Medicare.

Through PECOS you are able to:

  • Submit and track the status of your Medicare enrollment applications
  • View and update information
  • Complete the enrollment revalidation
  • Withdraw from the Medicare program

PECOS has many advantages over the paper Medicare enrollment application. The process is faster and paperless, including an electronic signature feature. Using the PECOS system gives you more control over your enrollment information and allows you to update and check your information easily.

Note: Even if you are enrolled in Medicare, PECOS may not have a record of your enrollment. This could happen if you have not submitted a Medicare application to report changes to your enrollment information since 2003.
