New provider roadmap: Provider enrollment 

Provider enrollment is the process of credentialing a provider and supplier to determine eligibility for enrollment into the Medicare program. Providers and suppliers must be enrolled in Medicare to render services to beneficiaries and receive reimbursement. 

Step 1: Choose submission method

There are three ways to submit your provider enrollment application(s):

Step 2: Complete application and supporting documentation

If you choose to submit your application online through PECOS, the application process will start by asking a few questions about your specific enrollment or business structure scenario. Your responses to the questions will automatically determine the required sections to be completed on the enrollment form.

There are multiple CMS Medicare enrollment applications. Your required application(s) will vary depending on your enrollment/business structure scenario. To learn which paper application(s) are required, access our:

This tool will ask specific questions regarding your potential enrollment and in turn will specify which application(s) need completed.

We also have tutorials on our website to assist with filling out application(s). The tutorials review each section of the application.

Step 3: Submit application and track status

The next step is submitting your application and supporting documentation. 

If you're completing your application via PECOS, make sure to select “complete submission”
