How will I be contacted during the processing of my application?

During the processing of your Medicare Enrollment Application, many questions may arise where the analyst needs to contact a knowledgeable individual who can assist them in getting the answer or documentation needed to complete processing.

Section 11 of the CMS-855S should be completed with the name, phone number and email address of an individual who is available to the analyst to answer any questions. Often this section is left blank and the analyst only has the name of the authorized official who is not always available. Not being able to contact someone for the required information can result in extended processing times.

Also, please be aware this individual can only be contacted during the processing of the application. Once processing is complete only individuals listed on the supplier file may receive or be contacted for additional information.
