Three Ways to Protect Your Medicare Enrollment Information

Protect your enrollment information from Medicare fraud with these three steps:

• Keep your Medicare Provider Enrollment, Chain, and Ownership System (PECOS) user ID and password secure and don’t share with others. Only an individual provider, Authorized or Delegated Official of an organizational provider, or Authorized Surrogate may view and update your enrollment information. Each individual gets their own credentials through the Identity & Access Management (I&A) System to access PECOS.
• Log in to PECOS and review your enrollment information periodically to ensure it's accurate, current, and there are no unauthorized changes.
• Report suspicious information (for example, information you didn’t submit) to your Medicare Administrative Contractor's (PDF) provider enrollment division.
