Q15. Is there additional information that provider or supplier organization needs to send to the Medicare contractor other than the electronically submitted application?

Yes. The signed and dated 2-page Certification Statement must be mailed to the Medicare contractor. In addition, a provider or supplier organization may need to submit certain supporting documentation, such as a copy of the CP-575 that was issued by the Internal Revenue Service. When the user submits the Medicare enrollment application for the provider or supplier organization, he or she will see the “Mailing Instructions, Print/Save Materials” page. This page lists the Certification Statement and the supporting documentation required to be mailed to the Medicare contractor in order to complete the enrollment action. Note: The signed and dated 2- page Certification Statement must be mailed to the Medicare contractor immediately, but no later than 7 days after submitting the application over the Internet. The Medicare contractor will not process an application submitted using Internet-based PECOS until it receives the signed and dated Certification Statement. The effective date of filing of an Internet-based PECOS enrollment application is the date the signed and dated Certification Statement is
received by the Medicare contractor for an enrollment application that has been successfully submitted to the Medicare contractor via Internet-based PECOS. The signature must be an original signature (not copied or stamped); we recommend that blue ink be used.


Q17. How will I know if I have successfully submitted the enrollment application for the provider or supplier organization?

Once the application has been electronically submitted in Internet-based PECOS, the “Submission Receipt” page appears. This page informs the user that the Internet application has been submitted to the Medicare contractor for processing. The “Submission Receipt” page reminds the user that the Certification Statement must be signed and dated by the Authorized
Official of the provider or supplier organization, and that the Certification Statement and the supporting documentation must be mailed to the Medicare contractor. Internet-based PECOS sends a notification reminder to each e-mail address listed in the Contact Person information section of the application. Note: The signed and dated 2-page Certification Statement must be mailed to the Medicare contractor immediately, but no later than 7 days after submitting the
application over the Internet. The Medicare contractor will not process an application submitted using Internet-based PECOS until it receives the signed and dated Certification Statement. The effective date of filing of an Internet-based PECOS enrollment application isthe date the signed and dated Certification Statement is received by the Medicare contractor
for an enrollment application that has been successfully submitted to the Medicare contractor via Internet-based PECOS. The signature must be an original signature (not copied or stamped); we recommend that blue ink be used.

Q18. I received an “invalid address” error. How do I resolve this error?
An “invalid address” error indicates that the address entered by the user in Internet-based PECOS was inconsistent with the United States Postal Service addresses. This page allows the user to continue by either saving the address that he or she entered, or by selecting the address that Internet-based PECOS is presenting.

Q19. What is the Special Payments address?
Because Medicare claims payments will be made by electronic funds transfer, the Special Payments address should indicate where all other payment information (e.g., paper remittance notices, special payments) should be sent.

Q20. Should I keep a copy of the enrollment application that I submit via Internet-based PECOS?

Yes. The user can print a copy for the provider or supplier organization’s records when using Internet-based PECOS. If the user submits the enrollment application to the Medicare contractor using Internet-based PECOS, do not send a paper copy of the enrollment application to the
Medicare contractor.

Q21. Will I be timed out when using Internet-based PECOS?
As a security feature, you may be timed out if you are inactive (that is, you do not hit any keys) for a period of 15 consecutive minutes. If you are in the process of completing an application in Internet-based PECOS and find you need to tend to something else, you should save your work.

If you do not save your work and are timed out, you will have to start over again.

Q22. How do I change my PECOS password?

You may change your PECOS password by going to PECOS at https://pecos.cms.hhs.gov, logging on, and following the instructions on the screens.
Note: CMS recommends that PECOS users change their PECOS passwords at least once a year. User IDs cannot be changed.

Q23. Who do I contact if I cannot remember the password I established to use for PECOS?
You should contact the CMS EUS Help Desk at 1-866-484-8049 or send an e-mail to EUSSupport@cgi.com for assistance.

Q24. How long does it take to change a PECOS password?
In most cases, a password change can be made in less than 5 minutes.

Q25. Can I change my PECOS User ID?
For security reasons, you cannot change your PECOS User ID.
