External User Service Links
The Centers for Medicare & Medicaid Services (CMS) has setup the External User Services (EUS) help desk. As part of quality customer support, the support site is a dedicated on-line resource to support users of several CMS systems listed below.

Provider Enrollment, Chain, and Ownership System (PECOS)
PECOS supports the Medicare Provider and Supplier enrollment process by allowing registered users to securely and electronically submit and manage Medicare enrollment information.https://pecos.cms.hhs.gov
Identity Management System (IDM)
Identity Management System (IDM) has been established to provide our Business Partners a means to apply for and receive a single User ID they can use to access many CMS applications.Provider Statistical and Reimbursement System (PS&R)
The Provider and Statistical Reimbursement (PS&R) System is a key tool for institutional healthcare providers, Fiscal Intermediaries (FIs), Medicare Administrative Contractors (MACs) and CMS. The system accumulates statistical and reimbursement data applicable to the processed and finalized Medicare Part A claims. This data is summarized in various reports, which are used by providers to prepare Medicare cost reports, and by FIs and MACs during the audit and settlement process. Access to the PS&R website is gained through IDM account creation, used to request application roles. Access to the Medicare Cost Report e-Filer website is also gained through the IDM system and PS&R application.https://home.idm.cms.gov/
