What Is the Provider Enrollment and Chain/Ownership System?


Quick Answer

The Provider Enrollment and Chain/Ownership System is an electronic method for medical providers and suppliers to enroll as Medicare providers. Known as PECOS, the system allows medical providers and suppliers to complete and submit enrollment applications, view, update and print enrollment information, complete the revalidation process, voluntarily withdraw from the Medicare program and track the status of a submitted Medicare enrollment application. PECOS is also used to communicate whether the applicant's enrollment has been accepted or denied.

PECOS is completely paperless and includes electronic signature and digital document features. It is faster than paper-based enrollment, and features a tailored application process that requires the applicant to submit only information relevant to enrollment, thereby enabling the applicant to maintain greater control over information released to Medicare. Using PECOS also makes it easier to verify and update information, and is less costly in terms of time and administrative costs.

In order to use the system, the provider or supplier must have an Employer Identification Number, which is the same number assigned to them by the IRS as a Taxpayer Identification Number.

The provider or supplier must designate an Authorized Official to submit the applicant’s enrollment application under PECOS and communicate with Medicare on enrollment and revalidation matters.The AO may in turn designate an employee as a surrogate to handle these duties.
