I Am Not Yet Enrolled in Medicare

You can only begin set up with EDI if you are a participating provider in the Medicare program. If you have not submitted an application to enroll in Medicare, please visit our Enrollment section of the site for guidelines.

If you have a pending enrollment application you will need to wait until the application is finalized and you receive final approval from CMS before you can set up EDI functions.

Providers with pending enrollment applications can check their application status.
