Due to scheduled maintenance, the Internet-based Provider Enrollment, Chain and Ownership System (PECOS) will be unavailable Monday, March 29, 2010, through Monday, April 5, 2010. Please note that the TrailBlazer Provider Enrollment Helpline will be unable to assist with PECOS-related inquiries during this time. If you would like to enroll or make a change to your existing Medicare enrollment record:
- Use Internet-based PECOS prior to March 29, 2010, or after April 5, 2010. For more information about Internet-based PECOS, see the appropriate “Getting Started” guide available in the Downloads section on the CMS Medicare Provider-Supplier Enrollment Web page. There are “Getting Started” guides for physicians and non-physician practitioners and for provider and supplier organizations.
- Complete and submit the paper Medicare provider enrollment application(s) (CMS-855) along with any required supporting documentation and mail the application(s) to the Medicare contractor. The CMS-855 forms are downloadable from the CMS Forms Web page.
Physicians and NPPs who have not enrolled or updated their Medicare enrollment since November 2003 will need to complete an initial enrollment application. Internet-based PECOS does not contain information for physicians and NPPs enrolled before November 2003 who have not updated their enrollment record.
