IACS Overview

Individuals Authorized Access to the CMS Computer Services (IACS) has been established to provide our Business Partners a means to apply for and receive a single UserID they can use to access many CMS applications. On this website you'll find information about the applications your IACS UserID can be used with, how to register for an IACS UserID, how to login to IACS, how to login to your application, and information about the Help Desks that support your applications. Your organization or CMS contact can help you with the information that you may need for registration such as application name, application role, Organization Legal Business Name, Taxpayer Identification Number or other information specific to your application. Not every CMS application requires the same information so it is important to get the specifics directly from your organization or CMS contact.
